DTSU666-CT is a CHINT three-phase (3P4W) energy meter, with external current transformers. It measures active and reactive energy in both directions, has accuracy class c (0.5s), a current range of 0.015-1.5(6) A and communicates over RS485 Modbus-RTU. It mounts on a DIN rail and is used for feed-in limitation and consumption monitoring.
DTSU666-CT is a CHINT three-phase (3P4W) smart energy meter for DIN-rail mounting, with external current transformers. It measures imported and exported active and reactive energy, communicates over RS485 Modbus-RTU and has an LCD display.
SOFAR manuals (HYD 5...20KTL-3PH, CH1000, 25-50KTLX-G3) name the CHINT DTSU666 meter for feed-in limitation and for measuring additional PV inverters.
It connects to external current transformers, which are not part of the product; the transformer ratio is set in the meter and in the monitoring app.
The meter measures energy and power (kW, kvar, kVA), current, voltage, frequency and power factor. The RS485 baud rate can be set from 1200 to 19200 bps (default 9600 bps); it operates from -25 to 55 °C, with IP20 protection.
