Mean Well HRPG-450-48 48V 9.5A 456W Power Supply

SKU CH-1MHM-2RE12

Delivers 48V at 9.5A with active PFC, constant current limiting and remote sense for reliable industrial power

  • TypeAT
  • Active PFC improves power factor efficiency
  • Constant current limiting protects against overload damage
  • Remote sense compensates for voltage drop
  • 100% burn-in test ensures reliable operation
  • Low no-load draw cuts idle energy waste

Industrial 48V Power Supply

The Mean Well HRPG-450-48 is a 456W single-output unit built for industrial and automation systems that require a stable 48V rail at up to 9.5A. It fits 1U low-profile enclosures and uses forced-air cooling from an integrated DC fan. Active PFC and universal AC input allow operation across global mains voltages without manual switching.

Universal Input and Protection Limits

The supply accepts a full-range AC input and can withstand a 300VAC surge for five seconds. Built-in protections cover short circuit, overload, over-voltage and over-temperature conditions. A constant current limiting circuit engages at 100% rated load, while no-load consumption stays below 0.5W. Remote sense compensates for voltage drop across long cable runs.

456W Output Capacity Decides Fit

The 456W rating at 48V 9.5A is the single figure that determines whether this unit meets your load requirement. Systems needing more power must consider the 600W variants, while lower-power builds can use the 300W or 450W models. Current sharing is only available on the 600W versions at 24V, 36V or 48V outputs.

商品問答

Which voltage and current rating should I select for a 48 V 9.5 A requirement?

The HRPG-450-48 delivers exactly 48 V at 9.5 A for 456 W continuous output, so choose this model when your load needs that voltage and current.

What does the 456 W rating mean once the unit is installed in a system?

It means the supply can provide up to 456 W continuously at full load, with built‑in active PFC and constant‑current limiting protecting connected equipment.

What input standard does the supply accept and what surge level does it withstand?

It accepts universal AC input across the full range and can withstand a 300 VAC surge for 5 seconds without damage.
