PRODUCT OVERVIEW
The QBR railway series offers 60 watts of output power housed in an industry
standard quarter-brick package with high power density. This QBR series features
wide input voltage range (4:1) from 43 to 160VDC (110 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 +105°C. The
modules offer Input under voltage lock out (UVLO), and are fully protected against
output overvoltage 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 series provides efficiency up to 92% with low No-Load power consumption.
The QBR series 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.
