Mean Well

Mean Well HRP-75-7.5 7.5V 10A 75W Power Supply

SKU CH-R9WK-X26A5

Delivers 7.5 V at 10 A with 75 W output, active PFC and full-range AC input

  • TypeProprietary Power Supply
  • Built-in active PFC function improves power efficiency
  • Constant current limiting circuit protects against overload damage
  • 100% full load burn-in test ensures reliability before shipment
  • 300VAC surge withstand for 5 seconds handles input spikes
  • Universal AC input full range supports global voltage standards

Industrial 7.5 V Power Unit

This Mean Well HRP-75-7.5 delivers a fixed 7.5 V output at 10 A for a total of 75 W. It suits engineers and technicians who need a regulated DC source for test benches, embedded controllers or custom industrial rigs. The proprietary form factor fits dedicated chassis rather than standard ATX bays. Buyers who want a modular PC power supply with multiple rails should look elsewhere.

Continuous Convection Operation

Active power factor correction keeps the input current clean across a universal AC range and the unit withstands a 300 VAC surge for five seconds. Cooling relies on free air convection, so output stays stable during prolonged full-load runs without fan noise. Constant current limiting and over-temperature protection prevent shutdown cycles when the load is sustained. The supply passes a 100 percent burn-in at full load before shipping.

Open-Frame Integration Steps

Mount the open-frame chassis on standoffs with adequate airflow clearance; no forced-air ducting is required. Connect AC mains to the input terminals and the 7.5 V load to the output terminals, observing polarity. Remote sense terminals are not fitted on this 75 W model, so voltage drop in long cables cannot be compensated. Verify that the enclosure provides the optional over-temperature protection if the installation demands it.

Questions sur cet article

How much heat will the HRP-75-7.5 generate when running at 75 W continuously?

It uses free-air convection cooling with no fan, so silent operation is assured; the unit is rated for 100 % full-load burn-in.

What AC input does the HRP-75-7.5 require to deliver 7.5 V at 10 A?

Universal AC input covers the full range, and the supply withstands a 300 VAC surge for 5 seconds.

Will the HRP-75-7.5 safely power legacy equipment that draws variable current?

Built-in constant current limiting and protections for short circuit, overload, over voltage and over temperature protect older loads.
