ATR KM211 电源模块

The threshold switch KM211 can capture DC voltages of 10mV...200V. In order to be able to exactly set the desired limit value, the total range is divided into 6 measuring ranges as specified in the technical data.
Fine adjustment in one measuring range is made by means of a trimmer in the front panel. The direction of the signal to be monitored can be separately preselected on two dip switches (+/-). When both switches are closed (state upon delivery) the comparator operates symmetrically. The switching hysteresis can be adjusted from 2...40% by means of another helical trimmer without changing the switch threshold during such adjustment.
The device have a galvanic separation wide-range power supply, that allows a connection at all usual ac and dc supply voltages (19Vdc...255Vac). They can be snap-on mounted onto support rails TS35.
