Product Introduction:
NM194U-9X1 Single-phase Voltmeter
Single-phase voltmeter is a measurement of voltage parameters in three-phase electricity, generally used in high-voltage distribution cabinets and low-voltage cabinets. unit is represented by V(volt), This product has the conventional measurement display function, can be integrated programming function, RS485 serial port and switching output and other functions, can realize the network with the monitoring system or remote transmission of data and other functions. The instrument adopts LED digital tube display form, which has high precision, good electromagnetic compatibility and high cost performance.
Product characteristics of single-phase voltmeter:
■ Effective value measurement, whole four digit display
■ Single-row LED displays A, B, C three-phase voltage at the same time
■ Optional with upper and lower limit alarm control function
■ Programmable to adjust the display value 1~999.9 through the panel key
■ Optional communication function, communication address, baud rate. Switching output
■ Software adjustment, high precision, long-term work without adjustment
