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 oltage, frequency, current,

power, acti e and reacti e energy, imported or exported. Energy is measured in terms of kWh, kVArh.

Maximum demand current can be measured o er preset periods of up to 60 minutes. In order to measure

energy, the unit requires oltage and current inputs in addition to the supply required to power the

product.

COUNTIS M33 supports max. 100A direct connection, sa es the cost and a oid the trouble to connect

external CTs, gi ing the unit a cost-effecti e and easy operation. Built-in interfaces pro ides pulse and

RS485 Modbus RTU outputs. Configuration is password protected.
