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.
