The primary switched MTM Power modules PMAS/PCMAS15 have been designed as universal compact power supplies with AC and DC wide input ranges for worldwide application and allow an efficient, cost-saving solution for different tasks where low power is needed. The modules have smallest dimensions of 50.8 x 50.8 x 20.0 mm (PMAS) and 84.0 x 51.0 x 22.0 mm (PCMAS). The power supplies are vacuum encapsulated, prepared for applications in Class 1 and/or 2 and comply to the Low Voltage Directives as well as to the up-to-date EN standards as regards CE conformity. Further features are rugged design, SMD-technology, automatic 100 % final test and 100-%-burn-in-test. The series PMAS/PCMAS15 offers 15 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).
