DESCRIPTION

The E50 Series power meter provides a solution for

measuring energy data with a single device. Inputs include

Control Power, CT, and 3-phase voltage. The E50 supports

multiple output options, including solid state relay contacts,

BACnet, Modbus RTU (with or without data logging), and

pulse. The LCD screen on the faceplate allows instant output

viewing. The meter is housed in a plastic enclosure suitable

for installation on T35 DIN rail according to EN50022. The

E50 can be mounted with any orientation over the entire

ambient temperature range, either on a DIN rail or in a

panel. The meter is not sensitive to CT orientation to reduce

installation errors.

FEATURES
