Supply intelligent controller tester

HN9100 intelligent controller intelligent controller tester main test items include: (1) measurement function testing and measurement scale intelligent controller features include: current measurement functions include A, B, C, N-phase current; voltage measurement functions include line voltage, phase voltage, the average voltage, voltage unbalance; power measurement functions include active power, reactive power, apparent power, power factor; energy measurement functions include active energy, reactive energy, apparent energy; required value Measurement functions include demand current and demand power; frequency; harmonics. Detection system according to the requirements specified in the product specification error of the size and type of measurement functions of the intelligent controller to test whether the qualified than the right, if there is some measure does not meet the requirements, the system is also part of the intelligent controller parameter coefficients (eg current, small standard value) for scaling, to reach the measurement accuracy. (2) Protection / alarm function detects the intelligent controller protection / alarm features include overload long delay, short circuit short delay, instantaneous overcurrent, ground fault, overload pre-alarm, current unbalance, phase loss, demand current, over- voltage, low voltage, voltage unbalance, under frequency, over frequency, phase sequence, reverse power, current, uninstall, MCR, ZSI and other protection methods. Detection system according to different specifications of the intelligent controller and controller setpoint signal input settings automatically validate various protection / alarm function operates correctly, the operating time is within the specified range of error. (3) "four remote" function test according to the communication protocol for remote adjustment of the intelligent controller, remote control, telemetry, remote function tests. (4) part of the actuator motor function, auxiliary contact function test.
