General Description
The new PMT series of panel mount power supplies is the latest offering from one of the world’s largest power supply manufacturers and
solution providers - Delta. PMT-48V350W1A☐☐ offers a nominal output voltage of 48V with a wide operating temperature range from 10°C to +70°C 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, Delta’s 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 100Vac
to 132Vac & 200Vac to 264Vac.
