PM-4324-160P Modbus RTU Multi-Channel Power Meter (100 A)

The PM-4324 Multi-Channel Power Meter monitors up to 8 three phase circuits or 24 single phase circuits, or any combination of single or three phase circuits.

The PM-4324 can measure up to 24 currents via external Current Transformers (CTs). This flexibility makes the PM-4324 perfect for multitenant facilities such as residential projects, office buildings and shopping malls. This compact instrument is designed to easily fit into existing panel boards or be flush mounted nearby, thus eliminating the need for expensive retrofit projects or for allocating extra space for the device.
