System integrators and panel builders rarely fail because they lack a power supply. They lose time when the standard 1.8-meter AC power cord that ships with every instrument creates a tangled mess behind the rack. Custom rack configurations require specific lengths to reach vertically mounted PDUs. Standard black cables make circuit tracing a nightmare. And for medical devices, a generic cord simply cannot meet the stringent leakage current and grounding requirements of IEC 60601‑1.
TPS Elektronik’s custom AC power cord service addresses these everyday but critical procurement gaps. Whether you need a short 30 cm jumper for a densely packed data center rack, a color‑coded cord set for rapid field service identification, or a hospital‑grade power cord with full regulatory documentation, TPS delivers OEM assemblies manufactured to your exact specification.
1. Why standard power cords fail in integrated systems
An off‑the‑shelf AC power cord is a one‑size‑fits‑all solution for a world that demands precise fit. In a 42U data center rack, a 2.5‑meter cord from a server to a vertical PDU leaves 1.5 meters of excess that must be coiled, zip‑tied, and managed. That excess blocks airflow, accumulates dust, and adds unnecessary weight to the cable management arm. Conversely, a cord that is just 10 cm too short forces the system integrator to mount a PDU in a suboptimal position, sacrificing valuable rack units.
Color is another standard failure point. A rack with twenty identical black power cords hides the one that needs to be disconnected during a maintenance window. Color‑coded cords — blue for primary power, red for redundant, yellow for bypass — eliminate this operational risk. TPS manufactures power cords with custom jacket colors, including RAL‑matched colors for brand consistency across OEM equipment fleets.
The connector choice is equally critical. A standard C13 appliance coupler works fine for office equipment, but in a factory automation cell, vibration loosens unprotected connectors. A locking C13 connector, a Schuko plug with a specific national approval mark, or a hard‑wired terminal block on one end may be required. TPS configures every cord with the exact connector combination the application requires. This level of customization is a natural extension of the full cable assembly capabilities described in our guide to EMS cable assembly, tested and documented.
2. TPS custom AC power cord service: build‑to‑print and engineer‑to‑spec
TPS Elektronik’s custom AC power cord service operates on two models. If the customer has a complete specification — cord length, wire gauge (AWG), jacket color, plug type, and any special overmolding or labeling requirements — TPS builds to print. The engineering team reviews the specification for compliance with the relevant national and international standards (such as IEC 60227 or UL 62), and production proceeds with full electrical testing of every cord.
If the customer knows the application but not the exact specification, TPS engineers can recommend the appropriate cord construction. This includes selecting the correct conductor cross‑section for the rated current and ambient temperature, specifying shielded versus unshielded construction for EMC‑sensitive environments, and choosing jacket materials (PVC, rubber, or halogen‑free compounds) that meet fire safety and environmental requirements. For specialized connector types such as BNC or SMA, refer to our technical guides on BNC connectors and SMA connector types.
Every cord undergoes a 100 % electrical safety test: continuity, polarity, and hipot (high‑potential) testing at the voltage appropriate for the cord’s rating and intended market. Test documentation is provided with each shipment, eliminating the need for the customer to retest incoming power cords. This testing protocol is part of the broader quality system described in our guide to tested and documented cable assembly.
3. Medical‑grade power cords and IEC 60601‑1 compliance
Medical electrical equipment subject to IEC 60601‑1 imposes requirements on the detachable power cord that go beyond standard commercial cords. The cord set must maintain reliable protective earth continuity even under mechanical stress. Leakage current must be strictly limited, and the plug and connector must carry the appropriate medical approvals — such as the green dot hospital‑grade marking in North America, or the EN 60601‑1 recognized component mark in Europe.
TPS manufactures medical‑grade AC power cords that meet these requirements. Every cord in a medical lot is individually tested and documented, supporting the medical device manufacturer’s obligation to maintain a traceable device history record. The cord jacket is typically a medical‑grade PVC or halogen‑free compound with resistance to cleaning agents and disinfectants commonly used in healthcare environments. For a broader discussion on medical‑grade cable assemblies, including fiber optic options, see our EMS fiber optic cable assemblies service page.
4. Application examples: data center, industrial, and medical
TPS custom AC power cords are deployed across three primary application domains:
- Data center racks: Short‑run 0.3 m to 0.6 m C13‑to‑C14 jumper cords for server‑to‑PDU connections, with color‑coded jackets for A‑feed and B‑feed identification. Angled connectors reduce the protrusion from the server face, improving airflow. Custom labeling includes sequential serial numbers for asset tracking.
- Industrial automation: Heavy‑duty power cords with rubber jackets for resistance to cutting oils and mechanical abrasion. Shielded construction reduces radiated emissions that could interfere with sensitive sensor circuits. Locking connectors or screw‑lock terminations prevent accidental disconnection in vibrating environments.
- Medical equipment: Hospital‑grade cord sets with green‑dot plugs, medical‑grade IEC C13 connectors, and full test documentation for every cord. Jacket materials that withstand aggressive cleaning protocols. Custom lengths that eliminate loops and tangles in crowded clinical workspaces.
These applications share a common requirement: the power cord must not be an afterthought. By partnering with TPS for custom cord assembly, system integrators and OEMs can turn the power cord into a designed component of the system, not a last‑minute purchase from the nearest hardware store.

TPS supports both prototype quantities and series production. The service is designed to be flexible, accommodating small pilot runs as well as large OEM annual contracts. Contact TPS with your specific volume requirements for a tailored quotation.
Can TPS provide power cords with specific national plug approvals?
Yes. TPS sources approved plugs for major markets including Europe (Schuko, CEE 7/7), North America (NEMA 5‑15, hospital‑grade), UK (BS 1363), and others. The appropriate approval marks are part of the cord assembly documentation.
Does TPS manufacture shielded AC power cords?
