Read MoreThe Delta PMT2 50W Series is a range of compact, high-reliability panel mount power supplies designed for industrial control, and automation applications where space, safety, and long service life are critical.
With an ultra-slim 29 mm low-profile design and universal AC input (90–264 Vac), the PMT2 series integrates easily into space-constrained control panels and enclosures. Multiple regulated DC output voltage options provide flexibility across a wide range of system requirements.
Built for demanding environments, PMT2 power supplies operate from -30°C to +70°C with fanless convection cooling, reducing maintenance and improving reliability. Ultra-low no-load power consumption (<0.3 W) helps minimise heat and energy waste inside panels.
Certified to IEC/EN/UL 62368-1 and additional global safety and EMC standards, the PMT2 50W Series delivers dependable, compliant power backed by Powerbox Australia’s local support and expertise.
