Railway Quarter-Brick QBR Series
Ultra-Wide Input (14-160V)
Up to 50 Watts DC-DC Converter
PRODUCT OVERVIEW
This QBR railway series offers up to 50 watts of output power housed in an industry
standard quarter-brick package. This QBR series features wide input voltage range
from 14 to 160VDC (72 Volts nominal), high efficiency isolation of 3000VDC and
provide a precise regulated voltage output.
All QBR models operate over the temperature range of – 40°C to +100°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 89%, 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.
