MTM Power has released primary-switched modules for vertical and horizontal mounting in rail applications. The PMAS5-S and PMAS-L primary-switched modules have been designed as a universal compact power supply 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 PMAS5-S/-L series offers 5W constant output and products are available with the single output voltages of 3.3VDC; 5VDC; 12VDC; 15VDC and 24VDC. The series is short-circuit protected, needs no ground load and has a reduced stand-by power.

With smallest dimensions of only 42mm x 30.1mm x 18.2mm (width by height by depth) and due to the vertical mounting the series PMAS5-S modules are extremely space-saving. The dimensions of the horizontal version (series PMAS5-L) are 42.6mm x 32.6mm x 17mm (width by height by depth). The modules are characterised by a compact and rugged design.

The power supplies are designed for PCB mounting and are vacuum encapsulated. They are prepared for applications in Class 1 and/or 2 and comply with the low voltage directive as well as the up-to-date EN standards as regards CE conformity. Furthermore the modules have a CB scheme and are VDE as well as UL/cUL approved.

The basis for the very high quality standard of the series is SMD-technology, 100%-burn-in test and an automatic 100% final test.
