SKU CH-V4ZK-GJXFM MPN JWS150-28/A

Delivers 28 V at up to 5.5 A from a universal 85–265 V input with 3000 Vdc isolation

  • Delivers 28 V at 5.5 A for stable single-rail power
  • Wide 85 to 265 V input suits global mains supplies
  • 3000 Vdc isolation protects sensitive downstream circuits
  • 47 to 63 Hz input frequency covers standard line frequencies
  • Seven-pin connector simplifies integration into existing designs

Industrial Single-Output Supply

The TDK JWS150-28/A is a 28 V switching power supply rated for 5.5 A continuous output. It accepts a universal AC input from 85 to 265 V at 47 to 63 Hz, making it suitable for global industrial equipment and test bench applications.

Isolated Single-Rail Architecture

A minimum isolation voltage of 3000 Vdc separates the single output from the mains input, protecting sensitive downstream electronics. The seven-pin connector provides the sole interface for power delivery without additional control or monitoring pins.

150 W Continuous Headroom

The unit delivers up to 150 W to loads such as motor drives, LED arrays or PLC systems that operate within the 5.5 A limit. It is not suited for applications requiring multiple voltage rails, higher current peaks or redundant parallel operation.

Questions about this item

What maintenance will the single 28 V output need over time?

The unit has no user-serviceable parts; keep ventilation clear and verify the 3000 Vdc isolation during periodic safety checks.

What limit appears first when the supply runs continuously at 5.5 A?

The 150 W maximum output power caps sustained load; exceeding 5.5 A triggers overload protection.

How much heat and noise does the JWS150-28/A produce during all-day operation?

Convection cooling with no fan means silent running; waste heat stays within the 85–265 V input design envelope.
