The primary switched MTM Power Modules PMA/PCMA15 are often used in applications with low power consumption and represent an efficient, cost saving alternative. These universal and highly compact power supply units are used worldwide due to their AC/DC wide input range. The small housings of PMA15 and PCMA15 have 76.0 x 50.7 x 22.7 mm and 110.0 x 50.8 x 23.0 mm dimensions, respectively, and use vacuum insulation permitting use in Class 1 and/or 2 applications according to the Low Voltage Directives and up-to-date EN standards as regards CE conformity. Both units are VDE, UL and cUL approved and feature SMDtechnology, 100-%-burn-in-test and automatic 100 % final test, rugged design, PCB mounting (PMA) or chassis mounting (PCMA) and are capable of providing stable 15 W output. Additionally, they are short circuit proof and require zero ground load.
