Selectable 12/24VDC power supply and battery charger

The Altronix SMP7 is a board-level power supply/charger for compatible access-control, security, and surveillance equipment requiring regulated DC power.

Key specifications

• Selectable 12VDC or 24VDC output
• 6A maximum supply current
• 24VAC or 28VAC transformer input
• Filtered, electronically regulated output
• Short-circuit and thermal-overload protection
• Built-in charger for sealed lead-acid or gel batteries with up to 0.7A charge current

Board only: Transformer, enclosure, batteries, distribution modules, and field wiring are sold separately. Confirm whether supervision is required; the standard SMP7 should not be described as the supervised SMP7PM model.

Calculate continuous load, lock inrush, voltage drop, auxiliary loads, battery capacity, and required standby time before installation. Use listed equipment and code-compliant egress and fire-alarm release arrangements where the supply serves locking hardware.
