The VKC03 offers 3 watts of output power from a package in an IC compatible 24pin DIP
configuration. VKC03 series have 4:1 wide input voltage of 9~36 and 18~75VDC. The
VKC03 features 1600VDC of isolation, short-circuit protection and as well as five sided
shielding. All models are particularly suited to telecommunications, industrial, mobile
telecom and test equipment applications.
