500 W 36 V Server Power Supply

This unit is a 500 watt AC-DC switching supply built into a desktop chassis for server and industrial equipment. It delivers a fixed 36 volt output at up to 21 amps with active power factor correction. The metal enclosure relies on natural air cooling for silent operation in test, measurement or telecom racks. It suits engineers who need a compact, single-output source with remote control and monitoring.

Sustained Load Behaviour

Efficiency reaches 90 percent thanks to zero-voltage switching that cuts internal losses during continuous operation. The converter is rated for ambient temperatures from minus 30 to plus 65 degrees Celsius while maintaining full output. Built-in protections against short circuit, overload, over-voltage and over-temperature shut the unit down before components degrade. The supplier advises against running the transformer above its rated current for extended periods to preserve service life.

36 Volt Fixed Output Constraint

The supply provides only a 36 volt DC rail; it cannot be adjusted to 24 or 48 volts despite those models existing in the same series. Remote sensing compensates for cable drop, and a DC-OK signal plus remote on/off allow integration into automated test systems. Buyers who need a different voltage or multiple output rails must select another model.

Questions about this item

How much heat and noise does the 500 W 36 V unit produce when running continuously?

The metal enclosure uses natural air cooling with no fan, so it runs silently; efficiency reaches 90 % to limit waste heat.

What external connections are needed before the chassis can deliver power?

An AC mains supply with inrush-current limiting and PFC is required, plus wiring for the remote switch, DC-OK signal and remote-sensing terminals.

Will the -30 °C to +65 °C operating range protect older test gear I keep in the same rack?

Yes, the supply maintains output across that full temperature span and includes short-circuit, overload, over-voltage and over-temperature safeguards.
