Why choose it

High efficiency and active power factor correction reduce energy waste and harmonic load on the mains. The wide input voltage range allows operation from both single-phase AC and DC supplies, increasing flexibility in diverse installations.

Ideal use cases

• Powering sensors, relays, and controllers in industrial cabinets
• Building automation and HVAC control panels
• Compact machinery and OEM equipment

Good to know

The output voltage is adjustable to compensate for voltage drops in long cable runs. The plastic housing provides double insulation (protection class II) without requiring a protective earth connection.
