Altronix AL400ULACMCB — 8 PTC Outputs Access Power Controller / Power Supply (12/24 VDC @ 4A)

Altronix AL400ULACMCB Access Power Controller

The Altronix AL400ULACMCB is a multi-output access power controller with a built-in power supply / charger — converts a single 115 VAC input into eight independently-controlled 12 / 24 VDC fail-safe / fail-secure outputs, perfect for Chicago commercial properties powering 4–8 doors from a single panel. Each output is PTC-protected (auto-resettable, 2.5 A) and has individually-selectable Fire Alarm disconnect (latching or non-latching) — satisfying NFPA 101 / IBC interlock requirements for maglock and electric-strike installations.

What’s Confirmed by the Official Altronix Spec

These specifications come directly from Altronix’s published AL400ULACMCB product page:

• Input: 115 VAC, 60 Hz
• Outputs: 8 independently-controlled fail-safe / fail-secure outputs
• Output voltage: 12 VDC or 24 VDC selectable
• Total output current: 4 A @ 12 VDC or 3 A @ 24 VDC
• Output protection: Class 2 PTC, auto-resettable, rated 2.5 A per output
• Fire alarm disconnect: latching or non-latching, individually selectable per output
• Battery backup: supports up to two 18 Ah / 12 VDC sealed lead-acid batteries
• Built-in features: filtered + electronically regulated outputs; short-circuit and thermal overload protection
• Compatible devices: magnetic locks, electric strikes, magnetic door holders

When AL400ULACMCB Fits — Multi-Door Access Control Power

The AL400ULACMCB earns its place when the project requires:

• Multiple doors (typically 4–8) powered from a single centralized panel
• Fire-alarm interlock wired into the power circuit so the doors release on fire alarm (code requirement for maglocks per NFPA 101)
• Auto-resettable PTC protection so a temporary short on one door doesn’t blow a fuse and doesn’t require a service call to replace
• Battery backup with extended runtime (two 18 Ah / 12 VDC batteries)

AL400ULACMCB vs. Other Altronix Multi-Output

Model	Outputs	Total Current	Protection
AL400ULACMCB (this page)	8 outputs	4 A @ 12 VDC / 3 A @ 24 VDC	PTC auto-resettable
AL600ULACM	8 outputs	6 A @ 12 / 24 VDC	Fused (3.5 A per output, 10 A main)
AL600ULMX	5 outputs	6 A @ 12 / 24 VDC	Individually protected per output
AL400ULX	1 output	4 A @ 12 VDC / 3 A @ 24 VDC	Single Class 2 output

For projects that need higher total current (6 A) and prefer fused-relay outputs, step up to the AL600ULACM. For single-output single-door applications, the AL400ULX is more economical.
