DESCRIPTION

The DHW50 series is the latest generation of high performance DC/DC converters

setting a new standard concerning power density. These converters offer 50 Watts of

continuous output power in a 2.0” x 1.0” x 0.43” encapsulated, shielded metal package.

All models have a 2:1 wide input voltage range and a precisely regulated single output.

Advanced circuit topology provides a very high efficiency up to 92% and an operating

temperature range of -40°C to +80°C. Further features include remote on/off, trimmable

output voltage, under voltage lockout as well as over load, over voltage, short circuit,

and over temperature protection. These converters are RoHS compliant and are ideal

for use in battery operated equipment, instrumentation, distributed power architectures

in communication and industrial electronics and many other space critical applications.
