The Delta PMR 240W Series is a compact panel mount AC/DC power supply range designed for industrial and household applications where low-profile installation, reliable performance and wide operating temperature capability are required. The series accepts a universal 90-264Vac input range, or 127-375Vdc input, and is available in 12Vdc, 24Vdc, 36Vdc and 48Vdc single output models. Built-in active PFC, convection cooling and a 30mm low-profile enclosed chassis make the PMR series well suited to installations with limited space.

PMR 240W models operate from -40°C to +70°C, with power de-rating above 50°C and below 100Vac. The series includes adjustable output voltage, DC OK LED indication, terminal block connection, and protection functions for overvoltage, overload/overcurrent, overtemperature and short circuit. Certifications and compliance listed in the datasheet include EN 62368-1, EN 60335-1, EN 61558-1/-2-16, UL 62368-1, CAN/CSA C22.2 No. 62368-1, IEC 62368-1, CE and UKCA.
