DHW50

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.

Notes & safety
Notes: 1. Transient recovery time is measured to within 1% error band for a step change in output load from 75% to 100%.
2. We recommend protecting the converter by a slow blow fuse in the input supply line.
3. To order the converter with a heatsink, please add the suffix “HS” to the model number. (Ex: DHW24S12-50HS)
4. Do not exceed maximum power specification when adjusting the output voltage.
5. The DHW50 series can meet EN61000-4-4 & EN61000-4-5 by adding a capacitor across the input pins. Capacitor: 330uF/100V
6. Other input and output voltages may be available; please call factory for ordering details.
Due to advances in technology, specifications subject to change without notice.
