HUGD-50中文资料50 Watt Power Hold-Up数据手册Gaia规格书

描述 Description

The Gaia Converter Hold up device HUGD-50 provides a state-of-the-art solution to the problem of maintaining electronic system operational during input bus drop-out for 50ms, 200ms or more. The HUGD-50 module provides an alternative solution to reduce the amount of capacitance needed by charging the hold up capacitor at a high voltage (typically 38V) while limiting the input current.
The HUGD-50 is connected between the line source and DC/DC modules. If an EMI filter and /or a pre-regulator are used, the HUGD-50 is connected between them and the converters. Basically the HUGD-50 charges the external capacitor to 38V while powering the DC/DC converters. If the power fails, the HUGD-50 generates a signal and the converters are powered from the external capacitor. The HUGD-50 can be used either with 16-40V or 9-36V input voltage DC/DC converters since the «power fail voltage» is externally adjustable by the user between 8.8V and 15.3V
