Example selection

Example: Users need to measure (three-phase three-wire system) three-phase AC voltage of 0-380V, rated current of 50A, three-phase current and power. They need to alarm when the measured voltage is higher than 400V, when the measured voltage is lower than 300V, and the power supply of the system is AC220V. In order to transmit the average three-phase voltage (0-380V), three-phase current (0-50A) and total active power (0-40kw) to 0-5V, 4-20MA and 0-20MA respectively, the data need to be transmitted to the upper computer.
