  • 7-year warranty reflects long-term reliability

LED Switching Power Supply

The NShi HLG-240H-42 delivers a constant 42V output at 5.72A with a 240W rating. Built-in active PFC and up to 94% efficiency suit LED lighting and street lighting installations. IP67 and IP65 rated enclosures allow indoor or outdoor mounting. Output current is adjustable via internal potentiometer on A-Type models.

Replaces older non-PFC drivers

This unit supersedes supplies lacking active power factor correction or surge immunity rated to 4kV under IEC61000-4-5. The jump is worth it when installations demand Class I Division 2 hazardous-location compliance or timer dimming functions. Multiple model variants cover adjustable voltage, 3-in-1 dimming and terminal-block wiring needs.

Check your setup before ordering

Verify the AC mains voltage does not exceed 305VAC and that the enclosure type matches the required IP rating. Confirm the load stays within the 240W limit and that wiring method suits the chosen A, B, C or Blank-Type variant. Ensure local regulations accept the 7-year warranty terms for the intended application.

Questions about this item

What IP rating does the HLG-240H-42 need for outdoor mounting?

The HLG-240H-42 carries IP67 and IP65 ratings, making it suitable for outdoor installations where water and dust ingress protection are required.

Which wiring step is most often missed when installing the HLG-240H-42?

Connecting the dimming control wires for the 3-in-1 function (1~10VDC, PWM signal, or resistance) is the step most often overlooked during installation.

How often should the HLG-240H-42 be inspected for dust buildup on its convection surfaces?

Inspect the convection-cooled chassis annually and clean any accumulated dust to maintain the 94% efficiency rating and thermal performance over the 7-year design life.
