Special precision AC constant current source is a high precision and high efficiency constant current source specially designed for small circuit breaker calibration table and standard table equipment. It is designed with special chip and power module as the core device and intelligent and efficient software algorithm. It has the characteristics of good stability, high precision, short adjustment time, high efficiency and convenient use. It can be used in delay stage, instantaneous stage, standard stage and other equipment.
In the technical field:
■ The product integrates many functions, such as current generation, action control, timing and counting of test products. The external interface is simple, the connection is reduced and the reliability of the system is improved.
■ It has two independent RS485 communication interfaces and standard Modbus-Rtu communication protocol. It can communicate with touch screen and upper computer at the same time. It is convenient to compose automatic debugging equipment and pipeline equipment.
■ Up to 2 transformers and 4 switchable gears can be equipped, and the type of transformer can be chosen arbitrarily. The current calibration method is simple.
■ The output current is not affected by the input voltage amplitude (working voltage range) and waveform change, which ensures the accuracy and consistency of the test.
■ Strong anti-interference ability, can adapt to all kinds of harsh industrial site environment, to ensure reliable and normal work;
Technological innovation:
■ Voltage range: 220V + 10%
■ Maximum output power: 20000VA (specifications selected by customers)
■ Output Accuracy: Indicative Error < 1%
■ Current stabilization time: <0.1S
■ Conversion efficiency: 85% at full load
■ Waveform distortion: THD < 3%
■ Volume: 310mm * 165mm * 85mm (less than 1000VA)
