€131 Tax included

€109 Tax excluded

DTSU666 is a CHINT three-phase (3P4W) energy meter, with direct measurement up to 80 A. It measures active and reactive energy in both directions, has accuracy class b (1.0), a current range of 0.25-5(80) A and communicates over RS485 Modbus-RTU. It mounts on a DIN rail and is used for feed-in limitation and consumption monitoring.

DTSU666 - Three-phase energy meter with direct 80 A measurement

DTSU666 is a CHINT three-phase (3P4W) smart energy meter for DIN-rail mounting, with direct measurement up to 80 A. It measures imported and exported active and reactive energy, communicates over RS485 Modbus-RTU and has an LCD display.

Main features:

  • Type: Three-phase energy meter
  • Measurement: direct, up to 80 A
  • Current: 0.25-5(80) A
  • Accuracy class: B (1.0)
  • Communication: RS485, Modbus-RTU
  • Mounting: DIN rail
  • Certification: MID B+D

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.

The meter is wired directly into the measured circuit, without external current transformers; the maximum current is 80 A.

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.
