The ML90.200 is a simple and cost effective approach to convert the AC voltage of a typical 3 phase system into a regulated DC voltage. It only requires 2 phase and thereby saves terminal space, terminal cost, wires, fuses and installation time. The ML90.200 is very compact, high efficient and easy to use. Furthermore, it fulfills the NEC Class 2 limitations. The input is internally protected, which makes external fuses unnecessary in many cases. Weighing only 360 g, it is a lightweight compared to the 50/60 Hz control transformers, which are commonly used for low-power control voltages where a neutral wire is not available. High immunity to transients and power surges as well as low electromagnetic emissions makes usage in nearly every environment possible.
