Acrel ADL400-F Three-Phase Energy Meter 80A Direct or CT Multi-Tariff RS485 MID
The ADL400-F is the three-phase panel meter for anyone who has to bill or account for energy, not just watch it: the -F version adds a 4-band multi-tariff function with daily programming over 14 time intervals and maximum demand logging. That is what you need to split consumption between users, verify a time band or keep an eye on contracted power.
It installs two ways: direct 3x10(80)A connection, with the conductors passing through the meter, or 3x1(6)A with current transformers — and it is this second version that carries MID certification, the one to use when the measurement has to be fiscally valid. Rated voltage is 220V/380V or 230V/400V ac.
Accuracy class on active energy is 0.5, and the meter also measures harmonics from the 2nd to the 31st: a figure that matters when you are chasing neutral overheating or disturbance on a board full of electronic loads. Local reading is on a 12-digit LCD, remote reading over RS485 with Modbus RTU, the standard any data logger or PLC can read. 35mm DIN rail format.
