Important Note
The output voltage can be adjusted between 21.6V and 26.4V DC. Check the connected device voltage requirement before adjusting the output. Full rated output is available under the operating conditions specified in the manufacturer datasheet. Output load must be reduced at high ambient temperatures and at low AC input voltages.
Safety Warning
Disconnect the mains power before installation or wiring. Verify Live, Neutral, and Protective Earth connections before powering the unit.This product contains exposed mains-voltage terminals and should be installed inside a suitable electrical enclosure by a qualified person.Do not touch the terminals while the power supply is energized.Maintain adequate ventilation around the unit and do not cover the ventilation openings.
