TECHNICAL DATASHEET PMT Panel Mount Power Supply 12 V 50 W 1 Phase / PMT-12V50W1A PMT Highlights & Features Universal AC input voltage range Power will not de-rate from input voltage 90 Vac to 264 Vac High MTBF > 700,000 hrs per Telcordia SR-332 Short Circuit / Overvoltage / Overload / Over Temperature Protections Versatile connector options (Terminal Block, Front Face, Harness) Safety Standards CB Certified for worldwide use Model Number: PMT-12V50W1A Unit Weight: 0.23 kg (0.51 lb) Dimensions (L x W x H): 98 x 98 x 38 mm (3.86 x 3.86 x 1.50 inch) 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 first range of PMT products will offer a nominal output voltage of 12V with 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 and will have no output power de-rating from 90 Vac to 264 Vac. This versatile series has three different connector options (Terminal Block, Front Face and Harness) and can also be converted into L Frame (PML) or Open Frame (PMB) type of power supplies to satisfy different application needs.
