The DR1P5 series offer 1.5 watts of output power from a package in an IC compatible 24

pin DIP configuration without derating to 71ºC ambient temperature and pin to pin

compatible to MKC03 series. DR1P5 series have input voltage of 4.5-5.5, 10.8-13.2 and

21.6-26.4VDC. DR1P5 features 500VDC of isolation voltage. A safety designed meet to

EN60950-1 and UL60950-1. All models are particularly suited to telecommunications,

industrial, mobile telecom and test equipment applications.
