The primary switched MTM Power modules PMAS5-S 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 series PMAS5-S offers 5 W constant output wattage and they are available with the single output voltages of 3,3; 05; 12; 15, 24 and 48 VDC. With smallest dimensions of only 42,0 x 30,1 x 18,2 mm (W x H x D) they are designed for PCB mounting and are extremly space-saving due to the horizontal mounting. The power supplies are vacuum encapsulated, 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. Further features are rugged design, SMD-technology, automatic 100 % final test and 100-%-burn-in-test. The series PMAS5-S is short circuit protected and needs no ground load.
