DC Power Supplies

The following Range of PSUs provide either a 12VDC (13.7) or a 24VDC (27.4) output. The changing of output voltage is controlled by a simple selector plug.

These units provide two separate output terminals and can house and charge two 12V 7Ah VRLA batteries. Typical uses are for powering door access controllers, electric releases and maglocks.

They are equipped with separate SPCO (Single Pole Change Over) contacts for 'MAINS FAIL' monitoring.

There is also an undedicated SPCO 'universal' relay that can be driven from a 12V or 24V DC supply. A typical use for this relay would be interfacing a fire panel with the power supply to de-power maglocks in the event of a fire condition.
