Product Overview The MTM Power DIN rail modules HSA75 have been designed as universal compact power supplies for the use under rough environmental conditions. They allow an efficient, cost-saving solution for different tasks where medium-ranged power is needed. The vacuum encapsulated devices offer a best possible protection against dust and humidity and are especially robust against mechanical stresses like shock and vibration. In case of overload and short circuit, they operate in stabilised current mode which ensures the start-up even under capacitive and inductive loads (motors). While continuously operating, the modules can also be used as a power source. Moreover, it is possible to connect several HSA75 in parallel to achieve a higher output power. As a standard feature, the perational status is indicated by an LED and can be polled at a power good output. They comply with protection class II, the Low Voltage Directive as well as the up-to-date EN standards as regards CE conformity. Further features are SMD technology supported production, automatic 100 % final test and 100 % burn-in test. The HSA75 are multi-purpose power supplies with high density and the dimensions of 43 x 115 x 75 mm (W x H x D).
