Product details

major function

Measurement of basic electrical parameters such as three-phase current, three-phase voltage, three-phase power, and frequency, as well as reactive energy measurement
◆ Phase sequence error indication of three-phase voltage and current, power symbol error indication
◆ Active pulse output indication, communication transmission and reception indication, reverse phase indication
◆ Support button setting function
◆ Current piercing direction setting
After power failure, all stored data will not be lost and can be maintained for more than 10 years
LORA channels can be set up through buttons or communication settings.
◆ Connect with the collection system through the supporting LOAR gateway device
■ LORA interface
Adopting a voltage CT isolation scheme to ensure that the antenna interface is isolated from the mains power at a voltage of over 2KV; The baud rate cannot be set, fixed at 9600 n 8 1
■ Communication protocol
◆ Supports Modbus RTU protocol and some DLT645-2007 protocols
■ Appearance
◆ Adopting a guide rail installation shell
■ Display format
◆ 8-bit LCD segment code display, supporting cyclic display and button display; 3 LED status indicators
■ Installation method
◆ 35mm standard DIN rail shell, flexibly adaptable to various distribution cabinets.
