Murata Power Solutions’ ACA5-20RM Series accept the output of external 5A current transformers (CTs) and accurately display the true-rms value of complex, non-sinusoidal ac currents up to 500A. Operation and setup is straightforward: simply pass the external 5A CT’s secondary 0-5A output leads through the ACA5-20RM’s on-board toroid sensor, apply ac power, and the ammeter is fully operational. All models are totally self-contained—other than the external 5A CT, no other user-supplied components are required.
