ACR10R-DxxTEx Bidirectional three-phase energy meter for reverse flow monitoring
The ACR10R-DxxTE4 three-phase DIN rail energy meter with split open current transformer terminals is suitable for power monitoring of grid-connected photovoltaic power plants, load control, and other applications. It is easy and cost-effective to install without removing the primary rail. It measures electrical parameters such as current, voltage, active power, reactive power, apparent power, frequency, power factor, etc. It supports multi-tariff energy metering, 4-quadrant energy metering, harmonic analysis, and energy monitoring. Remote signaling and remote control of circuit breakers are possible via digital inputs and relay outputs.

A notice:
1. "■" is the default assignment function, "□" is the mapping function. The above device uses 1-channel RS485 communication by default.
2. The connection mode corresponds to A1/B1/C1 etc. in the selection function.
3. Pulse output and relay output cannot be selected at the same time.
4. If you select the event logging function, you need to configure the DI or DO port.
