The Cosel FETA7000ST-144 is a high-power AC/DC converter designed to deliver a nominal output of 144V DC at 52A, providing up to 7488W of power. It accepts a wide AC input range of 170V to 264V at 50/60Hz, with derating required at lower input voltages. The converter achieves a typical efficiency of 91.5% at full load and a power factor of 0.98, contributing to energy-efficient operation.
Electrical specifications include a line regulation of 192mV maximum and a load regulation of 480mV maximum. Ripple and ripple noise are limited to 360mVp-p and 480mVp-p respectively over the 0 to +50C temperature range. The unit also features a maximum drift of 192mV and a temperature regulation of 480mV. Inrush current is limited to 60A maximum at 200VAC input, and leakage current is 0.85mA maximum per IEC62368-1.
This converter is suitable for applications requiring a stable, high-voltage DC power source from an AC mains supply. Its robust electrical characteristics make it appropriate for industrial, telecommunications, and other demanding power systems where reliability and performance are critical.
