Maintain dependable DC power for access control panels, signal equipment, and other security hardware with the Altronix AL175UL. Built as a power-limited supply/charger, it converts 120 V AC input into selectable 12 VDC or 24 VDC output, giving integrators flexibility across mixed-voltage deployments. Two individually PTC-protected outputs help isolate faults and support cleaner system design in environments where uptime and compliance matter. This model is designed for installations that need UL Listing for Access Control and an interface with Fire Alarm Control Panels. That makes it a practical fit for facilities where electrical code, inspection requirements, and documentation are part of the purchase decision. The wall-mount form factor simplifies placement in equipment rooms, closets, and security enclosures where space is limited but service access still matters. For teams standardizing on trusted infrastructure components, the AL175UL offers the kind of predictable behavior that reduces troubleshooting time and supports long-term maintenance planning. Its lifetime warranty and RoHS compliance further reinforce its value in regulated environments where reliability and procurement confidence carry real weight.
