OPERATION
The E50B2 DIN Rail Power Meter provides a solution for measuring
energy data with a single device. Inputs include Control Power, CT,
and 3-phase voltage. 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.
