TPS030-130W Pro Series DIN Rail Power Supply: 12V/24V IP30 Selection for RFQ-Ready Control Cabinets

Why the Pro Series is a BoFu fit for control cabinet projects

BoFu users usually arrive with a concrete project scope. They may already know the load voltage, cabinet envelope and quantity range, but they still need a supplier that can support selection, documentation and delivery. The TPS030-130W Pro Series is designed for exactly this stage: it is not an abstract power concept, but a selectable DIN rail range with defined 12V and 24V models, four power classes and clearly published electrical, mechanical and environmental data.

For a system integrator, the value is design clarity. A single series can cover smaller I/O loads, sensor supply, control relays, LED-related equipment and higher auxiliary DC loads without changing the installation concept. For a panel builder, the value is cabinet discipline: DIN rail mounting on TS35/7.5 or TS35/15, vertical installation, PC-110(+) UL94V-0 case material and compact width steps help simplify layout drawings and BOM comparison. For procurement, the value is a short model list, consistent technical structure and the ability to request alternatives or project support from TPS. For electrical engineers, the value is predictable input range, hold-up time, leakage current, ripple/noise data and derating behavior.

TPS Elektronik positions DIN rail power supplies as part of a broader DIN rail power supply portfolio, including compact GP Series units, the high-efficiency Pro Series and higher-power Peak DR+ units. This matters in RFQ discussions because many projects do not stop at one PSU. A cabinet may need compact auxiliary power in one area, high-efficiency 24V supply in another and power-boost capability for a separate branch. TPS can support the product selection path and, where the standard catalog is not enough, discuss equivalent solutions, integration requirements or project-level sourcing.

Model map: 30W to 130W, 12V and 24V

The Pro Series gives RFQ teams a clean selection ladder. Choose the output voltage first, calculate the continuous current with a practical reserve, then confirm cabinet width and ripple/noise limits. The 12V versions provide adjustable 12-15V output, while the 24V versions provide adjustable 24-28V output. All models use a nominal 90-264VAC or 120-370VDC input range, so the same series can be considered for many global control cabinet scenarios.

If the load is close to the maximum current, do not select only by nominal wattage. Check ambient temperature, continuous operation time, inrush behavior of downstream loads and the reserve required by your customer specification. For early supplier screening, share the load list with TPS and ask whether the TPS100-DR24Pro, TPS130-DR24Pro or another 12V/24V model is the best fit for the cabinet.

For a complete product discussion or multi-cabinet RFQ, use the TPS DIN rail contact path so that selection, availability, documentation and equivalent solution options can be reviewed together.

Electrical selection criteria that normally decide the RFQ

Input range, efficiency and cabinet heat

A global B2B project often needs one technical platform that can serve different mains environments. The TPS030-130W Pro Series supports 90-264VAC input or 120-370VDC input automatically, with 47-63Hz frequency. This makes it easier for engineering teams to discuss common cabinet platforms across markets, while still confirming the final installation conditions and local approvals during the RFQ.

Efficiency is listed as greater than 93% at 230VAC under maximum load with convection cooling. In a dense control cabinet, this is not only an energy number; it affects heat accumulation, component spacing and long-term reliability. Because the series is convection cooled, the layout should preserve airflow and avoid placing major heat sources immediately against the supply. The datasheet derating curves show full use up to 50°C ambient, then decreasing available output up to 70°C. For electrical engineers, this means load current must be checked against the actual cabinet temperature, not only against room temperature.

Hold-up time, inrush current and ripple/noise

The specification lists 20ms hold-up time at full load and 230VAC, 40A inrush current at cold start and leakage current of 0.2mA max at 265VAC/60Hz. These figures are important when the power supply is part of a larger cabinet with protection devices, upstream switching and multiple power supplies. They help define whether additional coordination is needed in the branch circuit or cabinet design.

Ripple/noise values differ by model and output voltage. For example, the 30W 12V and 70W 12V versions are listed with 120mV, while the 130W 24V version is listed with 200mV. In most industrial automation supplies, this is reviewed together with downstream electronics. If sensitive sensors, communication modules or analog measurement circuits are connected, the RFQ should include those loads so TPS can help verify whether the selected Pro model is sufficient or whether filtering, layout changes or another solution path should be considered.

Installation, cabinet layout and integration notes

In RFQ review, installation details are often more important than they first appear. A technically suitable DIN rail power supply can still delay a cabinet if the rail space, terminal access or airflow assumptions are wrong. The TPS030-130W Pro Series is intended for mounting on DIN rail TS35/7.5 or TS35/15 in a vertical orientation. The N, L and DC terminals accept cable in AWG26-14, corresponding to 0.15-2.5mm², with 300VAC rating. The front-side indicators provide DC-OK and DC-LOW status, helping commissioning teams identify supply state without opening the wiring logic.

The mechanical ladder is simple: the 30W model uses 91 x 23 x 60mm, the 70W model uses 91 x 53 x 60mm, the 100W model uses 91 x 71 x 60mm and the 130W model uses 91 x 90 x 60mm. This predictable width growth supports cabinet planning. Panel builders can reserve the right rail length early and avoid late redesign when the project moves from schematic to production. If the BOM must remain flexible between a 70W and 100W supply, for example, rail space and wire routing should be reviewed before quote release.

TPS can support this integration phase by reviewing the target voltage, load list, cabinet environment and product variant. For projects that need a compact 24V option, the TPS070-DR24Pro may be sufficient; for higher control loads, the TPS130-DR24Pro may be the better starting point. If the project requires a different performance profile, TPS can also discuss an equivalent or adjacent DIN rail solution instead of forcing a single model into an unsuitable application.

Compliance, reliability and procurement risk reduction

Procurement teams do not only buy wattage. They buy risk reduction. The Pro Series datasheet lists CE compliance with the Low Voltage Directive 2014/35/EU and EMC Directive 2014/30/EU. It also references LED safety certification EN61347-2-13 and design targets including IEC/EN/CSA/EN60601-1, EN62368-1, EN55011 Class A and EN55032 Class A. For medical or safety-related applications, the exact system-level compliance path should always be reviewed with project documentation, because the final cabinet or machine approval depends on more than the power supply alone.

Reliability data is also relevant for supplier screening. The datasheet lists operating temperature from -20°C to +50°C ambient, with derating from 50°C to 70°C, storage temperature from -40°C to +85°C, non-condensing operating humidity from 20-90%RH, altitude up to 3000m and MTBF demonstrated above 350,000 hours according to MIL-HDBK-217F at 25°C. The listed 3kVAC input-output withstand voltage for 60 seconds and 5-year warranty give purchasing and engineering teams additional parameters for risk comparison.

For a project buyer, this information shortens the supplier qualification conversation. Instead of asking only for unit price, the RFQ can ask TPS for the exact product model, datasheet, compliance notes, lead time, packaging, replacement options and documentation format. This is especially valuable for global B2B customers who need consistent products across multiple cabinet builds or regional variants.

Application fit and related TPS solution paths

The TPS030-130W Pro Series is well aligned with building automation, alarm and safety, LED lighting, environmental control systems, industrial automation equipment and medical equipment. These applications often need stable 12V or 24V auxiliary DC power in limited cabinet space. They also need a supplier that can understand installation conditions, not just ship a box.

If the project is more cost-sensitive and the load is modest, compare with the TPS GP Series compact switching power supply. If the project has larger transient demand or higher power levels, review the Peak DR+ 170% power boost discussion or the TPS100-320W Peak DR+ DIN rail power supply range. For test benches or lab supply needs rather than cabinet DIN rail installation, TPS also offers programmable DC options such as EA-PS 3200-02 C and EA-PSI 9000 DT. For energy storage, cell formation or regenerative test environments, TPS can support bidirectional power module discussions such as AC/DC bidirectional power modules for 14V cell formation or 750V bidirectional power module applications.

This related-solution view is important for RFQ conversion. A customer may initially ask for a 24V DIN rail power supply, but the real project may include a cabinet PSU, a test supply, a regenerative load and engineering support. TPS has the product and solution capability to discuss the broader power architecture, support equivalent selection and help global B2B teams turn a specification into a workable purchasing path.

RFQ checklist for faster quotation and project confirmation

A good RFQ does not need to be long, but it should remove avoidable uncertainty. When contacting TPS, include the target output voltage, continuous load current, peak current or start-up loads, ambient temperature inside the cabinet, required certifications, cabinet rail space, expected annual quantity, delivery schedule and any customer-specific documentation requirements. If you are replacing an existing supply, provide the existing electrical parameters and installation constraints rather than focusing on the old brand name. TPS can then evaluate the technical requirement and propose a suitable Pro Series model or an equivalent TPS-supported solution.

What each role should confirm before release

• System integrators: confirm load topology, reserve margin, downstream sensitivity and commissioning expectations.
• Panel builders: confirm DIN rail space, vertical mounting, wire size, terminal access and cabinet thermal conditions.
• Procurement: confirm model number, quantity breaks, delivery plan, documentation needs and long-term availability expectations.
• Electrical engineers: confirm input range, output adjustment, ripple/noise, hold-up time, inrush current, leakage current and derating.

For immediate product selection, review the TPS030-DR12Pro, TPS030-DR24Pro, TPS070-DR12Pro, TPS070-DR24Pro, TPS100-DR12Pro, TPS100-DR24Pro, TPS130-DR12Pro and TPS130-DR24Pro. For a quotation, supplier evaluation or project-level recommendation, contact TPS through the DIN rail power supply page.

Whether you need a single 30W DIN rail power supply, a 130W 24V cabinet supply or a coordinated product package for multiple automation cabinets, TPS can support product selection, equivalent solution review, documentation and project coordination for global B2B customers.

FAQ

Should I choose a 12V or 24V Pro Series model?

Choose the voltage required by the connected loads. 12V models cover 12-15V adjustment, while 24V models cover 24-28V adjustment. In automation cabinets, 24V is common for controls and I/O, but 12V may be required for specific subsystems, LED equipment or electronics.

How much power margin should be included in the RFQ?

Use continuous current, peak current, ambient temperature and derating to define margin. If the cabinet may operate above 50°C, review the derating curve before selecting a nominal wattage. TPS can help evaluate the load list during supplier selection.

Can the Pro Series support regulated or safety-sensitive systems?

The datasheet lists CE compliance with Low Voltage and EMC Directives, LED safety certification EN61347-2-13 and several design-to standards. The final system approval depends on the complete cabinet or device, so include compliance requirements in the RFQ.

Can TPS support equivalent replacement projects?

Yes. Provide the required voltage, current, space, terminal arrangement, compliance needs and operating conditions. TPS can review whether a Pro Series product or another TPS-supported DIN rail solution is technically appropriate.

Where should I send a project RFQ?

Use the TPS DIN rail power supply page for RFQ and solution consultation. Include the load list, target model, annual quantity and project timeline to speed up the response.
