Mean Well RSP-500-5 5V 90A Power Supply

The Mean Well RSP-500-5 delivers a single 5V output rated at 90A for 450W continuous power. It suits industrial equipment, test benches or custom DC systems that need a stable low-voltage rail. The built-in active PFC function corrects the input current waveform across the full universal AC range. This unit is not for builders who need multiple output voltages or a standard ATX form factor for a PC chassis.

Sustained Load Behaviour

Forced air cooling from the built-in DC fan maintains temperatures during continuous 450W operation. Protection circuits cover short circuit, overload, over voltage and over temperature conditions to keep the supply running safely under prolonged stress. A fan alarm on the related RSP-750 model signals airflow loss before thermal limits are reached. The supply is not for silent environments where any fan noise is unacceptable.

Build and Connectivity

The 1U low-profile enclosure fits standard rack shelves where vertical space is limited. Remote sense terminals compensate for voltage drop across long load cables, and an ON/OFF control input allows external sequencing. An LED indicator confirms power-on status at a glance. The unit is not for installations that require modular cabling or tool-less mounting brackets.

أسئلة حول هذا المنتج

How loud is the built-in DC fan when the RSP-500-5 runs continuously at 450 W?

The unit uses forced-air cooling from an internal DC fan; Mean Well does not publish a decibel figure for this model.

Which connectors or cables must I already have to wire the 5 V 90 A output into my system?

The supply provides screw-terminal blocks for the main 5 V output and for the remote-sense / ON-OFF control lines; you supply the mating lugs or wires.

Will the active PFC and 1U form factor fit alongside legacy AT-style chassis hardware I still use?

Yes — the RSP-500-5 is an AT-type supply with universal AC input and a 1U low-profile chassis, so it mounts in standard AT cut-outs without modification.
