2:1 Wide Voltage Input 1KV Isolated Regulated Short Circuit Protected Output Power Module: WRA/WRB Series

        WRA series dual output and WRB series single output DC-DC module power supply, is (2:1) wide voltage input, 1KVDC isolated regulated output type, DIP24 Pin metal shielded package, Output power: 2W-5W. Output has a self-recovery overload and short-circuit protection, the voltage will not rise when no load.

     Typical applications of DC-DC power modules (modular power supply), voltage polarity conversion, selection of external filter capacitors, overload and short-circuit protection circuits and series-parallel use are described in detail. Correct use can extend the service life of the product to avoid interference, overheating, self-excitation, poor start-up and other phenomena and irreparable damage.
