INTRODUCTION

Parts of the EM Series

The EM3555 DIN Rail Power Meter provides a solution for measuring energy data with a single device. Inputs include Control Power, CTs, and 3-phase voltage. The EM3555 supports multiple output options, including solid state relay contacts, Modbus, data logging, and pulse. The LCD screen on the faceplate allows instant output viewing.

The EM3555 Meter is capable of bidirectional metering. Power is monitored in both directions (upstream and downstream from the meter). The meter is housed in a plastic enclosure suitable for installation on T35 DIN rail according to EN50022. The EM3555 can be mounted either on a DIN rail or in a panel.

Observe correct CT orientation when installing the device.

Figure 1 shows the parts of the EM Series Compact Power and Energy Meter.
