Product Description
A compact size, light weight, simple mounting on the DIN-rail and the quick connect spring clamp terminals are what make the MiniLine power supplies so easy to use and install in seconds. A rugged electrical and mechanical design as well as a high immunity against electrical disturbances on the mains provides reliable output power. This offers superior protection for equipment which is connected to the public mains network or is exposed to a critical industrial environment. The MiniLine series offers output voltages from 5 to 56Vdc and a power rating of up to 100W. A DC-OK signal allows remote diagnostics. The supplementary MiniLine decoupling diode module MLY02.100 allows building of redundant systems or to protect against back-feed voltages.
