Devlin Switching Power Supply, PSU-F803-010-RS, 27.6V dc, 5.5A, 152W, 1 Output, 88 → 264V ac Input Voltage

Heavy duty wall mounting battery backed power supply units incorporating a switched mode power supply module that provides a regulated DC output plus a separate connection to the sealed lead acid battery. In the event of mains power failure the DC output is automatically maintained by the battery, while during normal working the battery is kept fully charged by an integrated trickle-charger. Suitable for use in security, access control, remote monitoring and similar applications.

Switched Mode technology provides high efficiency and low power dissipation, with a trickle charger to maintain the battery whilst AC is present
Short circuit, over-load and over-voltage protection whilst on AC power, plus battery protection against over discharge and reverse polarity
Optional secondary power supply can be installed (powered from the main DC output) for multi-voltage installations, see stk no. 537-5191
Rugged powder coated steel enclosure with sufficient space to contain 2x12Vdc 24Ah sealed lead acid batteries
