OVER CURRENT PROTECTION
The VKC03 offers 3 watts of output power from a package in an IC compatible 24pin DIP
configuration without derating to 71潞C ambient temperature. 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. A safety designed meet to
EN60950 and UL1950. All models are particularly suited to telecommunications,
industrial, mobile telecom and test equipment applications.
