The WPAX220 series is a high reliability 250W VME power supply especially designed for high end industrial, medical and rolling stock applications. The specified MTBF is over 200,000 hours at an ambient temperature of 45 degrees celcius. Its very low radiated emissions make it well suited for data-acquisition systems. Low losses means this power supply can operate between 0 and 50°C without fan and without derating. Standard features include a long hold up time of 40ms, power fail signal, active PFC to meet the EN61000-3-2, multiple output, low ripple and noise are integrated in the design.
