Applied Precision - Model CMR-U - Precision Electronically Compensated Voltage Transformer
The Precision Electronically Compensated Voltage Transformer CMR-U is a universal small-sized electronically controlled precision voltage transformer for galvanically isolated voltage transmission. The unity voltage ratio is dedicated for testing single-phase electricity meters with closed current and potential circuits but its versatility enables utilization in extensive applications.
The built-in active shielding between input and output eliminates capacitive current from input side to the isolated output device.
he Common Mode Rejecter (CMR) is an electronically compensated uncoupling unit for elimination of interaction of simultaneously tested electricity meters having interconnected current and voltage circuits (closed I-P links). The Precision Electronically Compensated Voltage Transformer CMR-U is a universal small-sized electronically controlled precision voltage transformer for galvanically isolated voltage transmission. The unity voltage ratio is dedicated for testing single-phase electricity meters with closed current and potential circuits but its versatility enables utilization in extensive applications. The built-in active shielding between input and output eliminates capacitive current from input side to the isolated output device. The CMR-U 1110 is constructed as universally applicable standalone unit with easy implementation to any existing test bench system. The unit has negligible additional power loss therefore no power increase is needed for closed link capability.
