Rectangular metal power supply unit with built-in cooling fan and terminal connections

Mean Well

Mean Well HRP-600-3.3 3.3V 120A 396W Power Supply

SKU CH-Z36B-0PX90

Delivers 3.3 V at 120 A with active PFC and constant-current protection

  • TypeAT
  • Delivers stable 3.3V output at 120A for high-current applications
  • Active PFC function improves power factor and reduces harmonic distortion
  • Constant current limiting circuit protects against overload conditions
  • Remote sense function compensates for voltage drop across long cables
  • 100% full load burn-in test verifies reliability before deployment

Industrial 3.3 V rail for high-current systems

This single-output power supply delivers a steady 3.3 V at up to 120 A for a total of 396 W. It is built for industrial equipment, test rigs and distributed-power architectures that need a clean low-voltage source with active power-factor correction.

Forced-air cooling with built-in protections

A built-in DC fan provides forced-air cooling while the unit runs. Protections cover short circuit, overload, over-voltage and over-temperature, and a constant-current limiting circuit keeps output in check. No-load draw stays below 0.75 W, and the active PFC function helps maintain efficient mains usage.

Remote sense and current-sharing for sustained loads

Under continuous load the remote-sense function compensates for voltage drop across long cables, and the DC OK signal reports status in real time. The HRPG-600 series also supports current sharing on 24 V, 36 V and 48 V models, while the 5 V standby output and remote on/off control simplify system integration. A 100 % full-load burn-in test is performed before shipment.

Questions about this item

How do I wire the remote sense terminals on this 3.3 V 120 A supply, and what mistake causes voltage drop?

Connect the sense pins directly at the load, not at the supply output, so the unit compensates for cable losses.

Which part will likely need replacement first during continuous 396 W operation?

The built-in DC fan is the only moving component and typically wears out before the electronic circuitry.

At what load does the constant-current limiting circuit activate on this 120 A model?

The circuit limits output once the current reaches 120 A, preventing overload while maintaining regulation.
