HZ5374 4000A Primary Current Injection Testing Device Fast delivery 24-hour customer service I customizable Product Introduction HZ5374 4000A Primary Current Injection Testing Device, referred to as (upper) is a test equipment developed by our company. It combines the advantages of similar products at home and abroad. It adopts numerical control technology and has strong anti-interference ability. Compared with the previous generation up , due to the low power consumption, large capacity self-coupling voltage regulator and the converter made of high magnetic permeability iron core, it has the advantages of large output power, small size and light weight. (1) Name: HZ5374 primary current injection tester. (2) Environmental group: it belongs to the group III instrument (it can be used in outdoor environment) in GB6287.1 -86 "General Program for Environmental Test of Electronic Measuring Instruments". (3) Input voltage: AC380V ±10%,three phase. (5) AC 0~4000A stepless adjustable, panel with digital display ammeter (7) Output waveform: The output current is a standard sine wave with tiny burrs, which is better than the power system requirements, and the ripple coefficient is less than 0.3%. Standard sine wave. (8) Output current mode: true effective value is continuously adjustable; ♦Beautiful and generous PVC panel ♦Directly display the test value of primary current and secondary current, which is convenient for test observation and recording. ♦Secondary measurement of the transformer, transformation ratio, and polarity are displayed at the same time ♦High measurement accuracy 0.5 level ♦Large power, small size, strong load capacity ♦Small in size and light in weight, the volume is only 30% to 70% of similar products, and it is very convenient to carry.
