Astrodyne's DH series of ultracompact (125.4-by-50.8mm) open-frame dc/dc converters offers up to 50W at currents up to 25A for telecom and distributed power applications.

The converters are available in single, dual, and triple versions and deliver 1.2Vdc to 100Vdc from an 18V to 75V input. All provide remote sensing with an output trim function.

This series guarantees line/load regulation to 0.1 percent, with ripple and noise performance as low as 35mV. Efficiency is as high as 89 percent. Standard features include protection circuitry for input undervoltage lockout, output overvoltage, and overtemperature. Hiccup mode circuitry handles overload conditions. Input-to-output isolation is >1.5kVdc.

The DH series is priced at $29 in OEM quantities. Delivery is stock to two weeks.
