CE-D series with MU4 case intelligent transducer functions programmable, true RMS measurement, digital tube display, power accumulation, the standard analog, switch, RS485 output. It makes the features of high precision, good electromagnetic compatibility, good looks and so on. Can set any one electrical parameter of voltage, current, power and power factor corresponding standard analog output according to the requirements. Can freely set the  corresponding limit value, hysteresis, upper limit alarm or lower limit alarm and other parameters of current  or voltage switching value,. Free to set the communication address (0-255), display variable ratio and so on. Press the "←" and "→" keys in front of the product panel to freely view the real-time values of voltage, current, active power, reactive power, power factor, frequency, and electrical measurement.
