Small Module Power Supply (WRA1205D-5W)

WRA/B 2~5series converter is a kind of isolation DC-DC converter with thin exterior, wide input voltage range, 2w-4w output. The input voltage divided into 4.5~9.0V, 9~18V, 18~36V and 36~72VDC; There are single output and dual output. The converter is widely applied to the industrial computers, automatic control, test instruments, and other occasions that need anti-interference power supply.
