  • TypeAT
  • Delivers stable 5 V at 90 A for high-current loads
  • Active PFC corrects power factor across the full input range
  • Constant current limiting protects against overload and short circuits
  • Remote sense compensates voltage drop over long cable runs
  • 100 % full-load burn-in test validates reliability before shipment

Industrial 5 V Power Supply

The Mean Well HRPG-450-5 is a 450 W switching power supply that delivers 5 V at up to 90 A. It accepts a universal AC input and includes active power factor correction, constant current limiting, remote sense, a DC OK signal and a 5 V 0.3 A standby output with remote on/off control. Forced-air cooling and a 1U low-profile enclosure suit rack or cabinet installation.

Suited For Single-Voltage Industrial Loads

This unit fits applications that need a single high-current 5 V rail such as LED arrays, electrochemical processes, test fixtures or legacy AT-style equipment. It will not suit builds that require multiple output voltages, dual-redundant hot-swap modules or current-sharing across parallel units.

Key Specification: 5 V / 90 A Output

The defining figure is the 5 V rail rated at 90 A, providing the full 450 W from one voltage. Confirm that the load draws at or below this current and that no auxiliary rails are needed before selecting this supply.

Questions about this item

What rack space does the 1U low-profile HRPG-450-5 need?

The 1U low-profile design fits a single rack unit in standard enclosures.

How do I wire the remote sense and remote ON/OFF on this supply?

Connect the remote sense leads to the load terminals to compensate for voltage drop, and use the remote ON/OFF pins with the 5V/0.3A standby output for control.

When should I expect to replace the built-in DC fan in the HRPG-450-5?

The forced-air fan is the only moving part; plan replacement when airflow drops or noise rises, typically after several years of continuous operation.
