General Description
The new PMT series of panel mount power supplies is the latest offering from one of the worlds largest power supply manufacturers and
solution providers - Delta. The product offers a wide operating temperature range from -10C to +70C and can withstand shock and
vibration requirements (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. This versatile series has three different connector options (Terminal Block, Front
Face and Harness) and can also be converted into L Frame (PML) type of power supplies to satisfy different application needs.
