QB SERIES Quarter-Brick
Wide Input Range 180 to 425 Volts
Up to 150 Watts DC-DC Converter
PRODUCT OVERVIEW
This QB series offers up to 150 watts of output power and is housed in
an industry standard quarter-brick package with high power density.
This QB series features wide input voltage range from 180 to 425 VDC
(300 Volts nominal), high efficiency, isolation of 3000 VAC and provide a
precise regulated voltage output.
All QB models operate over the temperature range of – 40°C to +105°C.
The modules 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. The output voltage can be trimmed to the required voltage
and the product includes Remote On/Off function.
This QB series provides efficiency up to 89%, meet industrial standard
and is the best choice for military, industrial, distributed power
architectures, telecommunications, and mobile applications.
