PM-4324-160P Multi Channel Energy Monitor

The PM-4324 Multi Channel energy monitor is capable of monitoring a maximum of eight three-phase circuits, twenty-four single-phase circuits, or any conceivable combination of them.

It employs external Current Transformers (CTs) to measure up to 24 currents. The PM-4324 mulit channel energy monitor is ideal for multitenant facilities like residential complexes, office buildings, and shopping malls because of its flexibility. There is no need for pricey retrofit projects or to set aside additional room for the device because this small instrument is made to fit into existing panel boards or be flush installed nearby.
