QBR SERIES Quarter-Brick
Up to 100 Watts DC-DC Converter
PRODUCT OVERVIEW
This QBR railway series offers up to 100 watts of output power housed in an
industry standard quarter-brick package with high power density. This QBR series
features wide input voltage range from 66 to 160VDC (110 Volts nominal), high
efficiency isolation of 2250VDC and provide a precise regulated voltage output.
All QBR 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 QBR series provides efficiency up to 93%, meet industrial standard and is the
best choice for railway system, industrial, distributed power architectures,
telecommunications, and mobile applications.
Please contact DATEL if your application requires different output voltage or any
other special feature.
