Delta Electronics has extended its the PMH series of panel mount power supply with 24V 91.2W output certified to NEC Class 2. The PMH-24V100WCNS accepts universal input from 85VAC to 264VAC in a full corrosion resistant aluminium body. Power will not de-rate across the entire input voltage range, providing full power even if the input voltage drops below the nominal voltage.

The highly efficient convection cooling construction can operate from -30 to 70°C and at a no-load power consumption less than 0.3W @ 115VAC and 0.5W @ 230VAC.

The NEC Class 2 model is specifically designed for household electrical appliances with safety approvals to pollution degree 3 as well as including IEC/EN 60335-1, IEC/EN 61558-2-16, IEC/EN/UL 60950-1 (with NEC Class 2).
