The FlatPAC-EN measures 9.2 × 5.0 × 1.4 inches, and provides up to 500 watts of output power from one to four isolated outputs. For EN compliance, the FlatPAC-EN can provide up to 425 watts. It can be configured with any of Vicor's 300 V DC input DC/DC converters in full-, half-, or quarter-brick sizes. Accepting inputs of 90 - 132 and 180 - 264 V AC at 47 - 63 Hz, the FlatPAC-EN uses a microprocessor-controlled autoranging function. Featuring passive harmonic current attenuation, FlatPAC-EN generates low EMI, simplifying noise filtering and contributing to its high power density.
