MTM Power, the specialist for individual power supplies, has introduced primary-switched HSD DIN rail modules with DC input voltage. The devices offer an input voltage range of 20VDC-72VDC and allow efficient solutions for different applications where low power is needed. Due to the thermoselective vacuum encapsulation the devices offer the best possible protection against dust and humidity and are especially robust against mechanical stresses like shock and vibration.

The 15W and 30W modules are available with the single outputs of 12V, 24V and 48V. The vacuum encapsulated modules offer an isolation of 3.3kVAC between input and output and comply with the up-to-date EN standards as regards CE conformity. Further features are SMD technology supported production, 100%-burn-in test and automatic 100% final test. The series HSD DC/DC dustproof converor is short-circuit protected and needs no ground load. The HSD modules are multi-purpose power supplies with high density and the dimensions of 29mm x 115mm x 76mm (HSD15) and 42mm x 115mm x 75mm (HSD30).
