The primary switched MTM Power modules PMAS/PCMAS24 have been designed as universal compact power supplies with AC and DC wide input ranges for worldwide application and comprise an efficient, cost-effective solution for different tasks where medium-ranged power is needed. The devices offer 24W constant output power and are available with 5, 12, 15, 24 and 48V output voltage.

The 24 and 48V output voltages are optionally available as Limited Power Source acc. to UL1310 NEC Class II. The dimensions of the cases are 76.0x50.7x22.7mm (PMAS) or 110.0x 50.8x23.0mm (PCMAS) resp.

The power supplies are vacuum encapsulated (EP 1 987 708, U.S. Patent No. 8,821,778 B2), prepared for applications in Class 1 and/or 2 and comply with 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, 100%-burn-in-test and automatic 100% final test.

The PMAS/PCMAS24 series is short circuit protected, needs no ground load, is designed for PCB mounting (PMAS) or chassis mounting (PCMAS) and has a reduced stand-by power. The modules have CB Scheme and are VDE as well as UL/cUL approved.
