Rayfull TC55M-DO three-phase CT-operated DIN rail energy meter with RS485 Modbus RTU, THD measurement and one digital output for external control. Connects through external 1A/5A, mV/mA or Rogowski-coil CTs on 1P2W, 2P3W, 3P3W and 3P4W networks.
Please note: the digital output is a control contact rated 5A 240V AC / 5A 30V DC, not a load disconnect. To switch a supply, wire it to the coil of an external contactor.
Lead time: 8 - 10 Days
