The Precision Electronically Compensated Voltage Transformer CMR-U is universal small-sized electronically controlled precision voltage transformer for galvanically isolated voltage transmission.
Properties
- DIN rail mounting possibility.
- Accuracy class 0,05 and 0,02.
- Compensation of residual capacitive current from the input to output.
- Operation without external power supply.
- Unity transfer ratio of the unit enables simple user test of functionality and accuracy.
- Built-in short circuit, overload and misconnection protection.
- Easy user-friendly mounting, negligible power consumption and built-in protection permit simple extension of any meter test equipment by closed I-P link capability.
