FAQ
What is the maximum current this PSU can deliver?
The HAY-PSU24V1ASMSP can deliver a maximum of 1A continuous current at 24VDC output voltage.
Can this power supply be used outdoors?
No, this unit is not suitable for outdoor installation. It is designed for indoor use only with an operating temperature range of -10°C to +40°C.
What happens if there is an overload or short circuit?
The PSU features full electronics protection that will shutdown the output until the overload or short circuit condition is removed. The red fault LED will indicate this condition.
How do I know if the power supply is working correctly?
During normal operation, the green LED indicates mains power is present and the unit should output 24-27VDC across the DC-OUT terminals. The red fault LED should be off during normal operation.
Can I control the output remotely?
Yes, you can control the output using either the local SW terminals or by connecting an external 24VDC supply to the 24V EXT terminals. The relay input can be configured for either NO or NC operation.
What type of fuse should I use if the output fuse blows?
You must use a quick blow fuse rated at the power supplying rating. Some equipment like electro-magnetic locks can draw excessive current on power-up, so ensure the fuse is appropriately rated.
