DA391: 12V 4A DC Steel-cased power supply with integrated UPS
This simple range of multi-purpose metal-cased power supplies provides 4A of 13.7VDC via individually fused outputs, for 12V DC equipment. The enclosure can also house a 7Ah VRLA battery, which the power supply will automatically charge while mains power is present and use in the event of mains power loss.
Integrated UPS battery back-up
A 7Ah VRLA battery can be placed in the mild steel enclosure and connected to the battery terminals of the PCB. This power supply will automatically float-charge the battery to capacity as required and provide continuous, uninterrupted power to the output from the battery if mains power is unavailable. Batteries are not included. This unit can be used with or without batteries fitted.
