HUAWEI - 250A Three-Phase Meter

The Huawei DTSU666-H 250A/50mA Smart Power Sensor is a three-phase (3P4W) current transformer energy meter designed for monitoring Huawei photovoltaic installations. It measures consumption, production , and grid injection in real time via three 250A/50mA current transformers, each supplied with a 5m cable.

This sensor differs from the DTSU666-HW/YDS60-80 by its exclusive operation via TC (and not in direct measurement), which makes it suitable for installations where the current per phase exceeds 80 A or for configurations where the TCs must be positioned away from the meter.

Class 1 accuracy (+/- 0.5% voltage, +/- 1% current/energy) and RS485 communication via Modbus-RTU (9600 bps) ensure compatibility with Huawei inverters and the FusionSolar platform. An LCD screen allows for direct on-site reading.

DIN35 rail mounting, dimensions 100 x 72 x 65.5 mm, weight 1.5 kg. Input voltage 176 to 288 Vac, measuring range: line voltage 304 to 499 Vac, phase voltage 176 to 288 Vac. Power consumption ≤ 1 W. Operating temperature: -25 °C to +60 °C, humidity 5 to 95% RH. 10 m RS485 cable included.
