SECO-LARM’s access control power supply features an enclosure large enough to fit two 12V/12Ah batteries, AC power failure supervision relay and battery failure/low battery supervision relay. It also has a DC power failure supervision relay (EAP-5D5Q only), auxiliary output relay. Adjustable voltage range compensates for voltage drop, and it has a built-in backup battery charger (battery not included), along with a selectable 2.2k Ω end-of-line resistor for AC failure and battery failure supervision relays via DIP switch. It offers a selectable delay timer (five seconds, five minutes, five hours) for AC failure supervision relay via DIP switch, LED status indicator for AC input, DC output and channel outputs. Operating input voltage is 110~240 VAC; it has a field-selectable 12 or 24 VDC output, total continuous output current: 5A@12VDC, 2.5A@24VDC. Also, individually fused power outputs (PTC-type fuses) are rated at 1.1A. It features failsafe or fail‑secure modes (EAP-5D5Q only), and its AC input fuse is rated at 3.15A. A heavy duty steel case has ventilation holes, a removable steel cover for easy access to power connections, a 6-ft. power cord and battery leads.
