product description:
unt-bc series programmable single / three-phase current, voltmeter, power meter, energy meter, using ac sampling technology, can directly measure the current and voltage in the three-phase grid. it can be used for local display and can be connected with industrial control equipment to form a measurement and control system.
the instrument can have rs-485 communication interface, compatible with modbus-rtu protocol; can convert power signal into standard analog output; or with one relay alarm output; or with four (two) switch input / two switch volume output. according to different requirements, through the instrument panel buttons, set and control the parameters such as ratio, alarm and communication.
