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 76.0×50.7×22.7mm (PMAS) or 110.0x 50.8×23.0mm (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.
