The primary switched MTM Power modules PMAS/PCMAS48 have been designed as a universal compact power supply with AC and DC wide input ranges for worldwide application. The dimensions of the PMAS case are only 90.5 x 65.5 x 33.5 mm and of the PCMAS case only 120.0 x 65.0 x 33.0 mm. This allows an efficient, cost-saving solution for different tasks where low power is needed. The power supplies are vacuum encapsulated and comply with the Low Voltage Directives as well as the up-to-date EN standards as regards CE conformity. Further features are rugged design, SMD-technology, 100-%-burn-in-test and automatic 100 % final test. The series PMAS/PCMAS48 offers 48 W constant output wattage, is short circuit protected, needs no ground load and has a reduced stand-by power. The modules are designed for PCB mounting (PMAS) or chassis mounting (PCMAS).
