SCP-50 Series - 50W AC-DC Single Output Security Power Supply



SCP-50 Series are a range of 50W AC-DC single output enclosed switching CCTV/Security power supplies, offering universal input voltage of 85 ~ 264VAC with energy saving concept and constant voltage output design. The SCP series are designed to have both terminal block and wires for output connection, which provides more flexibility to the installation; Other built-in functions include battery voltage detection, battery temperature compensation (by external NTC thermistor), battery polarity protection (by fuse), and protections for short circuit, overload, and over voltage.
