Main features
1. DTSD342-HLQ flush mount multi circuit power monitor has the advantages of high precision, good stability, strong practicability, powerful function, small size, easy installation, and excellent EMC performance.
2. Different communication modules are optional to meet different interface requirement of various customers.
3. Configured one channel RS-485 communication interface, our monitor supports MODBUS-RTU and DL/T645-2007 dual communication protocol.
4. Large screen LCD display, data cycle display.
5. Freezing and event recording

Main functions
The monitor can measure and display circuit bus voltage, current of four distribution three-phase circuits, active power, reactive power, apparent power, power factor and frequency. Through RS485 communication interface, our monitor can exchange data with the upper computer and calculate positive and negative active electric energy and reactive four-quadrant electric energy. Meanwhile, our monitor equips RS485 communication interface supporting DL/T 645-2007 and MODBUS RTU dual communication protocol, which greatly facilitates the automatic management of electricity utilization, as well as the wiring, installation, commissioning of the system. Besides, the user's investment and system costs are therefore reduced.
