The ACPM-1 offers a high accuracy current measurement over a 5A to 5000A range when used with the proper SCCT Series transformer. The unit communicates over a half-duplex EIA RS-485 interface. Standard baud rates are 9,600 and 19,200 baud. The ACPM-1 uses the industry standard Modbus RTU (binary) communication protocol, allowing up to 127 units per RS-485 subnet.
Its compact size allows for installation inside most electrical service panels and junction boxes. Detachable screw terminals makes wiring easy.
NOTE: A USB-to-RS485 adapter (available here) or a MEXM-1 or -2 is required to connect an ACPM-1 to a Davicom unit.
