INTRODUCTION
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.
