PSC-160B-C is a 160W 27.6V 3.8A AC/DC PCB type security power supply with 6x3 footprint, converted by the optional L-bracket and cover to be an enclosed unit. The unit has a universal input range between 90VAC and 264VAC and incorporates a built-in PFC function. In addition to the primary output there is a 27.6V 2A charger output that provides the backup power supply application required by access and security systems. PSC-160B-C delivers up to 90% high efficiency and can operate with air convection at temperatures of -30C through to 70C. This power supply is designed with thorough alarm features, including AC OK and battery low signalling; there is also a relay contact provided to facilitate user system design for the signals. Typical applications for PSC-160B include central monitoring systems, access control, security and alarm systems, emergency lighting and UPS systems.
