Seco-Larm EAP-1D1Q 12/24 VDC, 1 Amp, 1 Output Access Control Power Supply

The SECO-LARM EAP-1D1Q power supply is a versatile solution for powering access control devices in commercial or institutional entrances. It accepts 110-240 VAC input power and provides a filtered, electronically-regulated DC output selectable between 12 V or 24 V. The unit can deliver a total of 1 A at 12 V or 24 V output.

Built-in supervision relays monitor both AC power failure and low backup battery condition; these relays can be configured with a selectable end-of-line resistor and delay timer to integrate with building alarms. The enclosure has room for a backup battery (one 7Ah or two 4Ah) to keep output running if AC fails, and it will automatically switch to the battery source.

Installation is simplified by the rugged steel case with removable cover, multiple knockouts, status LEDs for AC input and DC output, and an adjustable output voltage range (12-13 V or 23-25 V) to compensate for voltage drop. It includes over-current and short-circuit protection to shut down in fault conditions.

This power supply is ideal for access control systems where a single zone or output is needed, such as one door or one strike/trip unit, and where supervision and backup power support are required.
