DIN Rail Power Centre with monitoring, output control and battery support
This DIN rail-mounting power supply unit features SPCO relay monitoring contacts, output controls and battery support. This unit will seamlessly switch from mains power to battery power in the event of a mains power failure. If this occurs, the unit will also change-over SPCO relay contacts for switching or signalling to other equipment that the mains power has failed. When mains power is restored, the unit will change-over the monitoring relay contacts and automatically re-charge the connected VRLA battery.
During prolonged mains power failure, if the connected VRLA battery is nearing depletion, the Low volt
SPCO relay contact will change-over to switch or signal to other equipment that the battery power is nearly depleted.
Deep discharge protection:
VRLA batteries can be damaged by complete discharge, which reducesthe life span and capacity of the battery. This power supply features deep-discharge protection and will automatically disconnect the battery before deep-discharge occurs. The battery is automatically re-connected for charging when mains power is available.
Output one (O/P1) provides a continuous power output regardless of the output control status. Output two (O/P2) can be switched on or off by the output control terminals. The output control enable
terminals will enable the output when closed-circuit and will disable (turn off) the output when open-circuit.
Restart function:
A PCB link jumper controls whether this function is enabled or disabled. When the jumper is fitted, the restart function is disabled. When the link jumper is removed, the restart function is enabled, and O/P2 will not re-enable when switched-output enable has been open-circuit and then closed-circuit, until restart
contacts have a momentary closed-circuit to confirm re-enable of the output.
Battery start:
Each module has a Battery start
button, this will enable the outputs from battery power without mains power connected.

Zintec-coated mild steel DIN Rail-mounting enclosures
These zinc-coated mild steel enclosures include DIN rail-mounting clips and have DIN-rail-clip mounting points on three sides. This allows installers to orientate and position the module in relation to the DIN-rail as required.
90V to 270V AC @ 47Hz to 63Hz
Designed to operate on standard mains power voltages world-wide this unit can accept a wide range mains-input of between 90V to 270V AC @ 47Hz to 63Hz.
