Frequently Asked Questions

• Can I parallel two units for more current?

  Yes. You can connect up to 2 units in parallel to increase output power.

• What happens if the output is shorted?

  The unit shuts down electronically and restarts automatically after the fault is removed.

• Is this power supply suitable for a 24 V battery backup?

  Yes, but you need an external buffer module (sold separately) for battery bridging.

• How do I adjust the output voltage?

  Use the built-in potentiometer to set the voltage between 24 V and 28 V.

• What is the max ambient temperature for full 20 A?

  You can draw 20 A up to 45 °C. Above that, derate by 5 % per Kelvin.

• Does it have a remote on/off control?

  No. It starts automatically when AC power is applied.

• Is the unit protected against reverse polarity?

  No. Ensure correct polarity at the output terminals.

• What type of circuit breaker should I use?

  Use a 10 A type C miniature circuit breaker (or Siemens 3RV2411 series).

• Can I use this in a humid environment?

  Yes, up to 95 % humidity (non-condensing) as per climate class 3K3.

• How long is the warranty?

  We offer a 12-month warranty against manufacturing defects.

Selection Guide

• • Check your total load current – choose 20 A for medium to large systems.
  • Consider ambient temperature – derate if above 45 °C.

• Verify input voltage – the unit auto-selects 120 V or 230 V AC.
• Need more power? Parallel two units (max 2).
• For marine or harsh environments, DNV approval adds confidence.
