Series Description

The GAIA Converter Hold up device HUGD-300 provides a state-of-the-art solution to the problem of maintaining electronic system in operation during input bus drop-out. Usually this approach uses very large capacitors because they are only charged at the voltage at which power fails. The GAIA Converter HUGD-300 module provides an alternative solution to reduce the amount of capacitance needed by charging the hold up capacitor at a high voltage value (adjustable from 31 to 80 VDC). It includes also a reverse polarity protection.
