Introduction
The MDR Power Supply Series supports inrush current protection of 30 A at 115 VAC and 60 A at 230 VAC. The series has an operating temperature range of -20 to 70°C, which ensures suitability for operating in harsh environments. In addition, the MDR Series has passed a 100% full load burn-in test, is UL/CUL listed, TÜV/CB certified, and CE marked. There are also models available with output ratings from 40 W to 60 W with 24 VDC output.
