Power Supplies — Engineering-Grade Power Distribution for Commercial Deployments
This category covers 193 working models of power supplies sourced manufacturer-direct or through channel-direct US distribution. Build the rest of your system around the architectural choices below — compatibility, environmental rating, and lifecycle decisions made here propagate through every downstream component you specify.
What to Look For
Voltage and amperage requirements come from the connected load. Cameras and access-control hardware typically use 12VDC or 24VAC; PoE-powered devices need a PoE injector or switch instead of a traditional supply. Sum the steady-state current draw across all devices on the supply, then add 25-30% headroom for inrush and growth. Undersized supplies fail quickly under sustained load.
Linear, switching, and PoE supplies have different efficiency, noise, and form-factor characteristics. Switching supplies are smaller and cooler-running but introduce switching noise that can affect audio circuits. Linear supplies run quieter electrically but generate more heat and weigh more. PoE injectors and switches are standard for IP cameras and access readers — pick by port count, power budget, and management capability.
Output redundancy and battery backup are the distinguishing features at the high end. Multi-output supplies with individually-fused outputs isolate device failures so one shorted camera doesn't take down the rest. Battery-backed supplies maintain operation during AC failure — code-mandated on most access-control and emergency systems. Sizing the battery for actual runtime requirement is more important than headline Ah capacity.
Enclosure type, mounting, and certification matter for code compliance and field reliability. NEMA-rated enclosures for outdoor/wet locations; lockable enclosures for tamper-resistant installs. UL 294 listing for access-control supplies; UL 1481 for fire-alarm supplies. Verify the AHJ's listing requirements before ordering — many jurisdictions reject non-listed supplies in commercial life-safety installs.

Frequently Asked Questions
Do I need a battery backup on my power supply?
For access control on egress doors, fire alarm systems, and most security-monitored installations — yes, code requires it. Battery backup runtime is typically 4 hours minimum for access control (24 hours for fire alarm). For surveillance cameras alone, battery backup is optional but recommended; a 30-minute UPS bridge handles most utility-power glitches and prevents reboot cycles that affect recorded video continuity.
What size power supply do I need for 8 PoE cameras?
If using a PoE switch, sum the per-camera PoE class budget: 8 cameras at 802.3at (PoE+, 30W max) need a switch with at least 240W total PoE budget. Add 20-30% headroom. Many 8-port PoE+ switches advertise 130W total budget — undersized for full-load 802.3at use. For 802.3bt (PoE++, 60-90W) devices like multi-imagers or large PTZs, plan even more aggressively.
Can I mix 12VDC and 24VAC devices on one supply?
Multi-output supplies (Altronix AL600ULPD8, LifeSafety FPO75) provide both 12VDC and 24VAC outputs from a single chassis, each individually fused. Mixing the two on a single output is not safe — voltage and waveform are incompatible. For larger sites, separate dedicated supplies per voltage simplify troubleshooting and isolate failures.
How do I calculate voltage drop on long cable runs?
Voltage drop depends on conductor gauge, current draw, and cable length. For 12VDC at 2A over 100 feet, 18 AWG drops roughly 1V (5%) — borderline acceptable. 16 AWG drops half that. For runs over 100 feet at sustained current, use a 24V supply at the source and step down at the device, or move to PoE which tolerates longer runs at typical commercial distances.
What's the difference between a power supply and a PoE injector?
A traditional power supply delivers DC (or AC) to a device through a dedicated power cable. A PoE injector adds DC power to the unused pairs of an Ethernet cable, so the device receives both power and data on the same Cat5e/Cat6. PoE simplifies installation and is the dominant choice for IP cameras and modern access readers. Traditional supplies are still preferred for high-current devices like maglocks and analog camera installations.
