The AC/DC converters (48 VDC) we have developed for the communications and broadcasting device market are mainly used as power supplies for communication devices such as servers, routers, and switching devices for communication carriers. They take AC power input from the system and output DC at voltages suitable for various loading devices. They are mainly ?48 VDC output/ 6 A to 4800 A class custom products.

■Overview

This is a load voltage compensating unit, using the booster converter method, inserted serially between a DC power unit (with storage battery) and the load unit.? When receiving power normally, it halts voltage-raising and supplies the input power from the DC power unit directly to the load device through bypass diodes.? When a power outage causes storage battery discharge and lowers input voltage, the unit starts voltage-raising, responding to the drop in input voltage by raising the unit's voltage as high as 10 V; the raised voltage is added to the input voltage, and the output voltage is controlled within a specific range.? Also, there are monitoring and control functions.
