Altronix AL400ULX Power Supply / Charger — 12 / 24 VDC, 4A / 3A | Vidimost Chicago

Altronix AL400ULX Power Supply / Charger

The Altronix AL400ULX is a single-output Class 2 power supply / charger — the workhorse Altronix unit Vidimost installs at Chicago commercial properties for single-output access control, burglar alarm, fire protective signaling, and nurse call equipment power. Converts 115 VAC / 60 Hz into either 12 VDC @ 4 A or 24 VDC @ 3 A (selectable), with a built-in charger for sealed lead-acid / gel batteries that automatically switches to backup power on AC loss.

What’s Confirmed by the Official Altronix Spec

These specifications come directly from Altronix’s published AL400ULX product page and datasheet:

• Input: 115 VAC, 60 Hz, 3.5 A; input fuse 3.5 A / 250 V
• Output (selectable): 12 VDC @ 4 A or 24 VDC @ 3 A; Class 2 rated, power-limited, electronically regulated
• Output voltage ranges (UL 603): 12 VDC at 11.5–13 VDC; 24 VDC at 23–26 VDC
• Battery charger: built-in for sealed lead-acid or gel batteries; max 0.7 A charge current; automatic switchover on AC loss
• Enclosure: 13 in W × 13.5 in H × 3.25 in D (330 × 343 × 83 mm); indoor wall-mount; 1/2 in and 3/4 in combination knockouts
• UL listings: UL 294 (Access Control), UL 603 (Burglar Alarm), UL 1481 (Fire Protective Signaling), UL 1069 (Nurse Call Equipment)

When AL400ULX Fits — Single-Output Access / Burg / Fire

The AL400ULX is the right pick when:

• The opening needs a single regulated 12 or 24 VDC output (one electric strike, one maglock, one access control panel)
• The project benefits from field-selectable voltage so the same Vidimost stock SKU covers both 12 and 24 VDC requirements
• Battery backup is required (the built-in charger handles sealed lead-acid / gel batteries directly)
• The installation must satisfy UL 294 (access control), UL 603 (burg), UL 1481 (fire), or UL 1069 (nurse call)

For multi-output applications where the project needs separate fused / PTC outputs for multiple devices, step up to:

• Altronix AL400ULACMCB — 8 PTC outputs at 4 A total
• Altronix AL600ULACM — 8 fused-relay outputs at 6 A total
• Altronix AL600ULMX — 5 individually-protected outputs at 6 A total

Where the Altronix AL400ULX Wins in Chicago

• Commercial single-output access control for one electric strike or maglock
• Burglar alarm system power with battery backup
• Fire protective signaling auxiliary power
• Nurse call equipment power at healthcare clinics
• Standalone single-door access control panel power
• Power for individual electric strikes, magnetic locks, magnetic door holders
