GENERAL DESCRIPTIONSHORT-FORM DATAThe ML90.200 is a simple and cost effective approachto convert the AC voltage of a typical three phasesystem into a regulated DC voltage. It only requires
two phases and thereby saves terminal space,terminal cost, wires, fuses and installation time.

The ML90.200 is very compact, high efficient andeasy to use. Furthermore, it fulfills the NEC Class 2limitations. The input is internally protected, whichmakes external fuses unnecessary in many cases.
Weighing only 360g, it is a lightweight compared tothe 50/60Hz control transformers, which arecommonly used for low-power control voltages
where a neutral wire is not available.
High immunity to transients and power surges aswell as low electromagnetic emission makes usage innearly every environment possible.
