Power Supplies
Dedicated power supplies convert building AC power into the regulated DC voltages that security cameras, access control locks, and other low-voltage devices require. Properly sized and installed power supplies prevent the voltage drops, noise, and overloading that cause unreliable device behavior.

Altronix AL600ULMX
The Altronix AL600ULMX is a 5-output Class 2 multi-output power supply / charger — 115 VAC input, 12 / 24 VDC selectable, 6 A total continuous current, individually-protected outputs. Lighter-duty companion to the ACM access power controllers when the project just needs distributed clean power without per-output fail-safe / fail-secure switching. The Chicago choice for CCTV multi-camera deployments and access control sites where the panel handles fail-mode switching and the AL600ULMX just delivers stable distributed power.
Altronix
Altronix ALTV1224DC2
The Altronix ALTV1224DC2 is a 16-output CCTV camera and accessory power supply — converts 115 VAC / 50-60 Hz into 12 VDC or 24 VDC distributed across 16 fuse-protected outputs (3.5 A per output, 6 A total). Filtered and electronically regulated. BC300 enclosure. The Chicago choice for mid-size CCTV deployments where 16 cameras / accessories need distributed regulated DC power from one centralized box.
Altronix
Altronix SMP3ET
The Altronix SMP3ET is a compact single-output power supply / charger — converts 115 VAC into a selectable 6 VDC or 12 VDC output at 2.5 A continuous, with built-in charger for sealed lead-acid / gel batteries and automatic switchover to standby battery on AC failure. Filtered and electronically regulated, with short-circuit and thermal overload protection. The Chicago choice for compact single-device installations — small access panels, low-current cameras, intercom auxiliary power.
