PMT-48V350W1A offers a nominal output voltage of 48 V with a wide operating temperature range from - 10C to +70C and can withstand shock and vibration (in accordance to IEC 60068-2-27 and IEC 60068-2-6 respectively). In addition to features like overvoltage and overload protections, Deltas PMT series of panel mount power supplies is unlike many other brands in the same price level. The PMT series is designed for cost competitive markets without compromising the quality of the components and product specifications. The series of products has an expected life time of 10 years and will have no output power de-rating from 100 Vac to 132 Vac & 200 Vac to 264 Vac.
