  • Chassis TypeDesktop
  • Universal AC input from 90 to 305VAC
  • Up to 96% efficiency reduces energy waste
  • Fanless convection cooling for silent operation
  • IP65 or IP68 rating suits harsh environments
  • Wide -55 to +70°C operating temperature range

Industrial power supply for harsh environments

The NShi HEP-320-24 delivers 24V at 13.34A for a total of 320.16W. It accepts a universal AC input range of 90~305VAC with built-in active PFC. The unit suits industrial systems that need reliable DC power in difficult conditions.

Sustained load with convection cooling

A fanless design relies on free air convection to manage heat across a -55~+70¡ãC operating range. High efficiency up to 96% reduces waste heat during continuous operation. Protections against short circuit, overload, over voltage and over temperature maintain stability under prolonged demand.

Sealed desktop chassis for daily exposure

The desktop chassis meets 6kV surge immunity and withstands 10G vibration for mounting in high-shock locations. IP65-rated A-Type models allow internal voltage and current adjustment; IP68-rated Blank-Type models fix those outputs. Both operate up to 5000 metres altitude in high dust, moisture, salt or outdoor settings.

Questions about this item

How much heat and noise does the fanless HEP-320-24 produce when running continuously?

The unit uses a fanless design cooled by free air convection, so it generates no fan noise. High efficiency up to 96% reduces waste heat, and it operates across a -55°C to +70°C range without active cooling.

What AC supply must already be present for the 90~305VAC input to work?

A standard mains supply anywhere from 90 VAC to 305 VAC is required. The built-in active PFC function ensures compatibility across this wide universal input range without manual voltage selection.

Will the IP65-rated A-Type version fit alongside older industrial gear that expects a fixed-output supply?

The A-Type model lets you adjust output voltage and current via internal potentiometers, while the optional Blank-Type is IP68 rated with fixed output. Choose the variant that matches the voltage and current expectations of your existing equipment.
