Datasheet

The PMH series of panel-mount power supplies from Delta Electronics is available at Luso Electronics. The series offers units with three distinct power ratings of 50, 100 and 200W, specifically designed for electrical appliances such as coffee machines, vending machines and general use in households.

The PMH-24V50WCAA, PMH-24V100WCAA and PMH-24V200WCBA are the respective 50, 100 and 200W units, and come with a number of approvals for both safety and EMC.

Safety approvals for units within the series include IEC/EN60335-1, IEC/EN61558-1 and IEC/EN61558-2-16; EMC approvals include EN55014-1 and EN55014-2 for appliances without an extra EMI filter required.

All the supplies feature a universal 85 to 264V AC input voltage and a nominal 24V voltage output.

The 50 and 100W units deliver full power operation between ambient temperatures of –20 to +50°C at altitudes up to 5000m, whereas the 200W unit offer full power operation from –20 to +45°C.

The series features a range of connector options for all three units, including terminal block, IP20, front face and harness types.

All three units are available in full corrosion-resistant aluminium casing with consistent width and depth dimensions of 97 x 38mm, and lengths of 98, 158 and 190mm for the 50, 100 and 200W units, respectively.

Finally, all the units offer a high MTBF of greater than 700,000 hours, as per Telcordia SR-332.
