2018-03-29 16:20

K series programmable digital display meter is a new generation product that can replace the original digital display meter directly. In addition to the normal measurement and display, the product also has the following functions and features:

1. Display frequency, communication address, baud rate and other buttons through the panel operation can be set at any time, and for a very flexible and convenient.
2. The measured value of the transmitting output can be selected, the output is 4~20mA, 0~5V, 4~12~20mA and other analog optional (K3, K4, K5, K6 both can be transmitting output).
3. RS-485 digital interface can be selected, using the standard MODBUS protocol, can be connected to 128 different meters, the transmission distance of 1.2km.
Wide range of application, high combination function: In addition to the three-phase power meter can directly measure the display power, but also through the keyboard to switch the measurement shows A, C phase voltage, RMS current, frequency and other electrical parameters, digital zero calibration, adjustment, high precision, cost-effective.
