Part 1 Product overview
1.1 Brief Introduction
COUNTIS M33 measures and displays the characteristics of single phase two wires (1p2w), three phase
three wires (3p3w,) and three phase four wires (3p4w) supplies, including voltage, frequency, current,
power, active and reactive energy, imported or exported. Energy is measured in terms of kWh, kVArh.
Maximum demand current can be measured over preset periods of up to 60 minutes. In order to measure
energy, the unit requires voltage and current inputs in addition to the supply required to power the
product.
COUNTIS M33 supports max. 100A direct connection, saves the cost and avoid the trouble to connect
external CTs, giving the unit a cost-effective and easy operation. Built-in interfaces provides pulse and
RS485 Modbus RTU outputs. Configuration is password protected.
