Datel 150W QB Series Of DC-DC Converters

QB series 150 watt ¼ brick DC-DC converters

>DATEL Inc. has announced the introduction of a new Quarter Brick (QB) series that can deliver up to 150 watts of power. This new line of high power density DC-DC converters from DATEL is the preferred choice for military, industrial, distributed power architectures, telecommunications, and mobile applications.

>Offering a wide 9-36V or 18-75V input range, this QB series delivers efficiencies up to 92%. The standard output voltages are 5, 12, 24, 28 and 48 volts that can be trimmed to a required voltage. These converters offer Input Under-Voltage Lock-Out (UVLO), and are fully protected against output overvoltage and over temperature conditions. All models have internal over current and continuous short circuit protection.

This QB series is offered in the standard Quarter-Brick footprint and operates over the extended temperature of -40ºC to +105ºC. It features a positive or negative On/Off Control function and 2250VDC of isolation. In addition, DATEL can supply the proper Heat Sinks for these converters.
