DESCRIPTION
The DH50 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.
Size: 2.00 x 1.22 x 0.71 inches (50.8 x 31.0 x 18.0 mm)

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. The DH50 series can meet EN55022 Class A with external capacitors in parallel with the input pins.
• 12Vin Models: 22µF/25V 1210 MLCC
• 24Vin Models: 3.3µF/50V 1210 MLCC
• 48Vin Models: 2.2µF/100V 1210 MLCC
4. To meet EN61000-4-4 & EN61000-4-5 an external capacitor across the input pins is required. Suggested capacitor: CHEMI-CON KY
330µF/100V
5. Do not exceed maximum power specifications when adjusting the output voltage.
6. To order the converter with a heatsink, please add the suffix “HS” to the model number. (Ex: DH12S12-50HS).
Due to advances in technology, specifications subject to change without notice.
