MTM Power GmbH has announced the HSD series of primary switched DIN rail modules with DC input voltage. The devices offer an input voltage range of 20-72VDC and allow efficient solutions for different applications where low power is needed. Due to the thermoselective vacuum encapsulation (EP 1 987 708, U.S. Patent No. 8,821,778 B2) the devices offer a best possible protection against dust and humidity and are especially robust against mechanical stresses like shock and vibration.
The 15 or 30W modules are available with the single outputs of 12, 24 and 48V. They 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 is short circuit protected, needs no ground load and operates in a temperature range between -25 and +70 °C.
The HSD series consists of multi-purpose DIN rail power supplies with high density and small dimensions.
