SKU CH-DJJM-R4B5Z

A 48V 7A server power supply with active PFC, constant current limiting and remote sense for 336W output

  • Chassis TypeDesktop
  • Active PFC improves power efficiency
  • Constant current limiting protects against overload
  • Remote sense maintains accurate voltage delivery
  • 100% burn-in test validates full-load reliability
  • Five-year warranty backs long-term operation

48V 336W Server Chassis Power Supply

The NShi HRPG-300-48 is a desktop-format server chassis power supply delivering 48 volts at 7 amps for 336 watts of continuous output. It suits integrators building 1U rack systems or industrial equipment that require a regulated 48V DC source with active power-factor correction.

Universal AC Input With 300VAC Surge Tolerance

The unit accepts a full-range AC input and can withstand a 300VAC surge for five seconds, protecting downstream hardware during line disturbances. Active PFC keeps harmonic distortion low, while no-load consumption stays below 0.5 watts. Forced-air cooling via the built-in DC fan sets the practical thermal limit for continuous full-load operation.

1U Low Profile With Remote Management Features

A 1U low-profile enclosure allows dense rack mounting without exceeding standard height allowances. Built-in remote sense compensates for voltage drop across long cable runs, and a DC OK signal plus remote on/off control enable monitoring and sequenced startup. Constant-current limiting, short-circuit, overload, over-voltage and over-temperature protections maintain safe operation under fault conditions.

Highlights

  • Active PFC improves power efficiency
  • Constant current limiting protects against overload
  • Remote sense maintains accurate voltage delivery
  • 100% burn-in test validates full-load reliability
  • Five-year warranty backs long-term operation
