ME440 panel three-phase multi-function power meter that supports direct current input or external open Roche coils or voltage CT
The ME440 supports three-phase, three-wire and three-phase, four-wire systems.
Realize line-free testing, simplify testing steps, and save construction costs.
The amount of electrical parameters collected at the front end is transmitted to the system data center in real time.
The RS485 communication interface is standard and is compatible with a variety of configuration systems via the standard Modbus-RTU protocol.
The current, voltage, power factor, harmonics, power, electrical energy and other electrical parameters on the A, B and C phase grids can be measured.
Roche coils convert currents to corresponding voltage signals through electromagnetic induction, and ME440 captures the voltage signals output from Roche coils to convert the corresponding current values. The ME440 measures current and voltage and counts real-time valid values for three- and N-phases. In addition, power factors, visual power, reactive power, harmonics, etc. can be calculated.
