35W Single-Output Security Power Supply and Battery Charger
Mean Well Enterprises Co. Ltd. PSC series, which targets security applications includes an additional charger output with a relatively small current to provide charging for a back-up battery. Like other PSC series, PSC-35 is able to be offered in either the PCB type (84.6 x 50.8 x 24mm) or the enclosed type (with L-bracket and cover, 86.4 x 59.6 x 30mm) configuration for different application requirements.
PSC-35 series accepts the input from 90Vac through 264Vac; at the output end, 13.8Vdc (adjustable from 12- to 15-Vdc) and 27.6Vdc (adjustable from 24- to 29-Vdc) are provided, respectively, to fulfill the most frequently-used voltage demand for security applications, 12Vdc and 24Vdc. The working efficiency of this series is up to 86% and the entire series can operate between -30 and +70 degrees under free air convection.
PSC-35 series is designed with complete protection functions, including short circuit protection, overload protection, over voltage protection, battery low protection, and battery reverse polarity protection (by fuse). It also provides the alarm function, via TTL signal output, for AC OK and battery low. Moreover, PSC-35 series is complied with international certificates such as UL, CUL, TUV, CB, and CE. Suitable applications include security systems, emergency lighting systems, alarm systems, DC UPS systems, central monitoring systems, access systems, and etc.
