Description
The Smart Power Sensor DHSU1079-CT is a three-phase energy meter designed for measuring and monitoring electrical parameters in three-phase installations. The device works with three current transformers (CT) 250 A/50 mA and provides registration of active energy, power, currents, voltages, frequency, and power factor. It features an LCD display with auto-loop display and an RS485 communication interface.
Manufacturer: Huawei Digital Power Technologies Co., Ltd. The manufacturer ensures that the devices comply with CE, RCM, and UKCA standards. The product is delivered with factory-configured communication parameters (address, baud rate, data format), and the documentation includes instructions for installation, wiring, and setting parameters via buttons on the panel.
Electrical Parameters
- Nominal Voltage and Frequency: 230/400 V AC, 50/60 Hz
- Current Measurement Range: 0–250 A (input through CT 250 A / 50 mA)
- Current Input: CT, 250 A/50 mA
- Energy Measurement Accuracy: Class 1 (tolerance ±1%)
- Grounding System: three-phase four-wire (3P4W) or three-phase three-wire (3P3W)
- Communication: RS485 (A/B), supports serial protocol; parameters: parity/stop/baud configurable
- RS485 Transmission Speeds: 1200 / 2400 / 4800 / 9600 / 19 200 / 115 200 bit/s (default 9600 bit/s)
- Working Power Supply Voltage Range: 0.7–1.3 Un
- Operating Temperature: from -25°C to +60°C
Mechanical Parameters
- Mounting Mode: DIN rail mounting 35 mm
- Dimensions (approx. from documentation): height 99.3 mm, width 72 mm, depth 66 mm (also marked on the drawing: 53 mm and height of the part 45 mm and 35 mm for the mounting element)
- Voltage Connections: terminals Ua (terminal 3), Ub (6), Uc (9), Un (10)
- CT Connections: IA*, IA, IB*, IB, IC*, IC to terminals 13,14,16,17,19,21 (cables provided by the manufacturer)
- Communication Connection: RS485A terminal 24, RS485B terminal 25
- Maximum Tightening Torque for Screws (voltage terminals): terminals 3, 6, 9, 10 – max. 0.9 N·m, recommended torque 0.6 ± 0.1 N·m
- Maximum Tightening Torque for Screws (CT and RS485 terminals): terminals 13,14,16,17,19,21,24,25 – max. 0.5 N·m, recommended torque 0.34 ± 0.05 N·m
- Mechanical Notes: each phase (Ua, Ub, Uc) has internal protection (fuse and thermistor) — external fuses on voltage lines are not required
