Compact single output power supplies designed to over up to 300W

Powersolve has a series of compact, single output AC/DC converters designed to provide up to 300W across a wide operating temperature range of -30C to +85C. The seven model PSY300 series power supplies are open PCB units with a 3” x 5” footprint. Operating from a wide 90VAC to 264VAC input range with active PFC, models in the series provide output voltages from 12VDC to 54VDC with output currents from 3.7A to 16.67A convection cooled and from 5.55A to 25A with fan cooling. A 12V, 0.3A fan supply is a standard feature. The company can also supply models with output voltages from 9V to 57VDC, still within the safety approvals, but subject to minimum order quantities. The units are efficient (up to 92%) and feature a no load power consumption figure of 0.25W without fan and the integral LED power indicator. They are protected against short circuit, over current, over voltage and over temperature and feature remote sense and power fail signal. The series meet all relevant EMI radiated and conducted standards and have a number of safety approvals including CE, CB EN60950-1 and UL/cUL60950-1.
