The Schlage 505ULAC is a 505 Series Power Supply designed for access control applications, converting 110VAC/60Hz input to a power-limited DC output. Its primary function is to provide a stable and regulated power source, with field-selectable output voltages of either 13.8 VDC @ 1.0A or 27.6 VDC @ 1.0A nominal. This power supply is intended for operation in a controlled indoor environment.
The 505ULAC features a printed circuit board (PCB) that manages power conversion and monitoring. It includes three indicator LEDs to provide real-time status updates: a red LED for DC output presence (on DC+ and DC- terminals), and two green LEDs near the supervision terminal block. One green LED indicates a connected battery, while the other signifies the presence of AC line voltage. The supervision terminal block offers connections for two relays, each with Common, N.O., and N.C. contacts, rated at 1A @ 28VDC. A key safety feature is the Emergency Interface Relay (EIR), which is standard to the power supply. The EIR's purpose is to cut power to fail-safe locks in emergency situations, ensuring compliance with safety protocols. When using the EIR relay circuit to supply power to fail-safe locks, such as electromagnetic locks, power must come from connector J6, terminals: -OUT & +OUT. The relay output reflects the condition of the EIR relay for signal or control, rated 5A @ 30VDC.
