Altronix T3M7724LCK1DQ Dual-Voltage Power Supply with Battery Backup
Overview
The Altronix T3M7724LCK1DQ is a large-format, dual-voltage power supply and battery management enclosure designed for commercial and enterprise security installations that demand sustained output under load — and can't afford a gap in power during an outage. Running on 115VAC/60Hz input, the unit simultaneously delivers regulated 12VDC and 24VDC output to support mixed-voltage device populations in a single enclosure, eliminating the need for separate supplies at each voltage tier. With a combined output of up to 10A at 24VDC and 6A continuous at 12VDC, this is a supply sized for serious multi-device installations, not single-camera drops.
Altronix power distribution products are a long-standing choice in the access control and surveillance camera integration space. Browse the full Altronix catalog for the complete line of power supplies, distribution boxes, and accessories.
Key Features
- Dual-Voltage Output (12VDC and 24VDC): Supports both 12V and 24V device loads from a single enclosure — practical when your installation mixes 12V cameras with 24V locks, readers, or controllers. No second supply, no second conduit run for AC.
- 10A @ 24VDC / 6A @ 12VDC Continuous Output: The 24VDC rail at 10A continuous is the primary workhorse for high-current device strings. The 12VDC rail at 6A continuous handles a secondary device population. Plan your load budgets before wiring — running either rail at the continuous ceiling under worst-case temperature is the spec to size against, not the peak.
- 4 × 12VDC/12AH Battery Capacity: Four sealed lead-acid batteries at 12AH each give you substantial standby runtime depending on the connected load. At lower system draws, this translates to hours of backup — enough to bridge most utility interruptions without generator involvement. Batteries are housed internally, keeping the installation footprint consolidated.
- 115VAC / 60Hz Input, 4.2A Max Draw: Standard North American single-phase power input with a 5A/250V input fuse for overcurrent protection. The 4.2A maximum draw fits a standard 20A branch circuit comfortably even when sharing with other low-current devices.
- Operating Temperature 0°C to 49°C: Rated for environments up to 49°C (approximately 120°F), which covers most interior mechanical rooms, closets, and IDF/MDF spaces. Not rated for outdoor or uncontrolled environments — if your install is in an unconditioned space that exceeds 49°C in summer, account for that in placement.
- CE European Conformity: CE marking confirms the unit meets applicable European safety and electromagnetic compatibility directives — relevant if the installation spans facilities in EU jurisdictions or if purchasing policy requires CE-listed power equipment.
