Frequently asked questions
What does universal AC input mean for my connection?
It means the supply accepts a wide range of mains voltages without a manual switch. Check the label on the unit for its exact input range before connecting it to your mains supply.
Does the built-in fan need attention during operation?
The fan is controlled by the unit and runs for cooling. Keep the ventilation openings clear of dust and obstructions so the supply can dissipate heat at full load.
