    Product info sheet for the SECO-LARM Enforcer EAP-5D1Q Access Control Power Supply (1 output, 5A@12VDC / 2.5A@24VDC), and the EAP-5D1MQ — the PC board only, sold separately from the EAP-5D1Q enclosure kit.

    Features

    • AC power failure supervision relay and battery failure supervision relay.
    • Selectable 2.2K-ohm End-of-Line (EOL) resistor for both AC failure and battery failure supervision relays.
    • Selectable delay timer (5 sec, 5 min, 5 hours) for the AC failure supervision relay.
    • LED overload indicator with automatic shutdown for short-circuit protection.
    • Fuse-protected AC input.
    • Built-in back-up battery charger; automatically switches to back-up battery if AC fails.
    • Individual AC input and DC output LED status indicators.

    Power

    • Field-selectable for 12VDC or 24VDC output via DIP switch.
    • Operating input voltage: 110–240 VAC.
    • Adjustable voltage range to compensate for voltage drop: 11–15 VDC or 23–26 VDC (set via VR1 rotary knob).
    • Supply current: 5A @12VDC, 2.5A @24VDC.
    • AC input fuse rating: 3.15A (glass fuse).
    • DC output overload sensing with red LED indicator and automatic shutdown on short circuit.

    Enclosure (EAP-5D1Q)

    • Heavy-duty steel case with removable steel cover for easy access.
    • Ventilation holes to prevent heat build-up.
    • Room for two 7AH backup batteries inside the enclosure.
    • 6-foot power cord and battery leads included.
    • Dimensions: 12-3/16" x 12-7/16" x 3-9/16".
    • Knock-out on the cover for an optional cam lock.

    Connections & Controls

    • 110–240 VAC input with fuse and AC input LED status indicator.
    • Battery failure & low battery supervision relay output — wire to an audio/visual warning device (e.g., SECO-LARM SL-126A power supply annunciator).
    • AC failure supervision relay output — wire to an audio/visual warning device, with selectable delay timer DIP switch and End-of-Line (EOL) 2.2KΩ resistor DIP switch.
    • Battery presence and low battery monitor DIP switch.
    • DC output terminal block with DC output LED status indicator.
    • Back-up battery terminal (12VDC battery, optional, not included) with polarity (− / +) marked.
    • DIP switch for 12 or 24 VDC output selection, alongside the VR1 rotary knob for fine voltage adjustment.
