The three-phase voltage and current combination meter is a type of meter with programmable measurement, display, and digital communication functions for data display, collection, and transmission, with a measurement accuracy of 0.5 level. It achieves LED/LCD on-site display and remote RS485 digital interface communication using MODBUS-RTU communication protocol, and can also be equipped with extended functions such as four switch inputs, four switch outputs, and four analog outputs.
Characteristic
Measurement: three-phase voltage and three-phase current.
Display: three rows of LED Nixie tube display, or high visibility, STN blue screen, wide viewing angle, high-quality, high-definition LCD display.
Communication: RS485 communication, Modbus RTU protocol, with networking function.
Input: Four switch inputs.
Output: Four switch quantity outputs, four analog quantity outputs.
Extension: Signal can be directly connected from current and voltage transformers, and input parameter ratio can be programmable on site.
Function: Full four digit display, range display can be set arbitrarily.
