High Efficiency DIN Rail Power Supply for Energy Sensitive Applications

Why Efficiency Matters in DIN Rail Power Supplies

In industrial control panels, every watt lost as heat directly impacts cabinet temperature, component lifetime, and energy costs. A high efficiency DIN rail power supply reduces wasted energy, allowing smaller enclosures, lower cooling requirements, and higher system reliability.

Conventional power supplies often operate at 80–85% efficiency, meaning 15–20% of input power is dissipated as heat. TPS‑DR Series achieves up to 93% efficiency (depending on model and load), making it a true energy efficient power supply for modern automation.

For procurement and engineering teams, choosing a green power supply DIN rail</strong> model also aligns with corporate sustainability goals and helps meet energy regulations such as ErP Lot 9.

Technical Highlights of TPS‑DR High Efficiency Series

The TPS‑DR Series is built around a resonant (LLC) topology that delivers high efficiency across a wide load range. Key features include:

• Ultra slim DIN rail power supply design – widths as narrow as 23 mm (for 30 W models) save valuable panel space.
• Isolated DIN rail power supply with reinforced insulation (4000 Vac) for safety and SELV compliance.
• DIN rail  with PFC – active power factor correction (PFC) ensures compliance with EN 61000‑3‑2 and reduces input current harmonics.
• Wide input range (85–264 Vac / 120–370 Vdc) makes it an international power supply DIN rail suitable for global installations.
• Low heat dissipation power supply design minimizes temperature rise inside enclosures.

All models meet SELV power supply DIN rail requirements (EN 62368‑1) and are certified for industrial control panels (UL 508, cUL).

SKU Selection: Power Ratings and Voltages

The TPS‑DR Series is available in common industrial voltages (12 V, 24 V, 48 V) and power ratings from 10 W to 100 W, with peak power capability for motor or capacitive loads.

• DIN rail power supply 24V – 10 W (ultra compact, ideal for sensors and small controllers)
• 30 W DIN rail power supply (for PLCs, HMIs, and small I/O systems)
• 60 W DIN rail power supply</strong> (for mid‑range automation)
• 100 W DIN rail power supply</strong> (for larger control panels and multiple loads)
• 12 V variants for embedded systems: 10 W, 30 W, 60 W, 100 W
• High‑power DIN rail models: 100 W (12 V) and 100 W (24 V) with 150 W peak (up to 4 s).
• 150 W DIN rail (12 V) for demanding applications.

For applications requiring temporary power boost, the TPS100‑DR+ series offers up to 320 W peak power.

Low Heat Dissipation and Thermal Integration

Thanks to high efficiency (up to 93%), the TPS‑DR Series generates significantly less heat than conventional designs. This translates directly to lower internal cabinet temperatures and reduced cooling requirements.

Key thermal advantages:

• Natural convection cooling sufficient for most ratings (no fans needed).
• Low heat dissipation power supply – less than 5 W wasted power at full load for a 100 W unit.
• Compact size (<23 mm width for 30 W models) allows dense packing without thermal issues.

For panel builders, this means fewer derating concerns and simpler thermal validation. The installation and wiring guide provides practical advice on spacing and airflow.

Global Compliance: PFC, SELV, and International Approvals

When your equipment ships worldwide, you need a power supply that meets diverse regulatory requirements. The TPS‑DR Series is designed as a true international power supply DIN rail</strong>:

• Active <strong>PFC (Power Factor Correction) compliant with EN 61000‑3‑2.
• SELV (Safety Extra Low Voltage) per IEC 62368‑1 and UL 508.
• Reinforced isolation (4000 Vac) suitable for industrial environments.
• EMC compliance: CISPR 32 / EN 55032 Class B (conducted and radiated emissions).
• CE, RoHS, and UKCA markings.

These certifications simplify your system approval process and reduce time‑to‑market.

Typical Applications for Energy‑Sensitive Environments

Thanks to its high efficiency and compact size, the TPS‑DR Series is widely used in:

• Industrial automation – PLCs, HMI panels, I/O modules (PRO series for demanding environments).
• Building automation – HVAC controls, lighting systems, access control.
• Medical equipment – <strong>medical DIN rail power supply</strong> variants (2 MOPP, low leakage current) available on request.
• Test and measurement – <strong>PLC power supply DIN rail</strong&gt; for reliable 24 V rails.
• <strong>Renewable energy – inverters, monitoring systems.

For critical syste

ms, the compact DIN rail power supply</strong> design ensures easy integration even in retrofitting projects.

Installation Tips for Panel Builders</h2>

To get the mo

st out of your high efficiency DIN rail power supply&lt;/strong>, follow these best practices: <ul>

• Use the supplie

d DIN rail clips to mount on TS35 (35 mm) rail.

• Observe minimum spacing (typically 20 mm above/below) to allow convection cooling.
• Wire input and output with appropriate gauge (24–12 AWG) and torque to manufacturer specifications.
• Separate AC and DC wiring to reduce EMI coupling.
• For peak‑load applications, consider the TPS100‑DR+ with 170% power boost to avoid oversizing the PSU.

Detailed instructions are available in the DIN rail installation and wiring guide.
