The PQM-200 is a computer-based Power Quality Monitor with up to 48 input channels. It combine functionalities of a Power Quality Monitor, Disturbance Recorder, Power Fault Recorder, Transient Recorder, Phasor Measurement Unit (PMU) and high precision energy meter. The input modules are fully-isolated (isolation voltage 6kV) and provide a synchronized sampling rate of 144 kS/s per channel and 24 bit resolution. An Automatic Anti-Aliasing filter together with extremely low-noise ensures signal quality and signal processing.
