Comprehensive upgrade – ITECH provides more accurate current source function for battery AC impedance test


ITECH IT7800 high-power programmable AC power supply, IT7900 regenerative power grid simulator, and IT7900Phigh-performance regenerative power grid simulator will be fully upgraded in the near future for free – the new current source function will be added to further improve the functionality and applicability of the products. The new function can provide users with more accurate, stable and automatic current output to meet users’ testing needs in different fields and improve testing efficiency and accuracy.

A current source is a power supply device that can provide a constant current to the load and keep the output current stable even when the external grid power supply fluctuates and the impedance characteristics change. In order to further reduce the test cost of customers, ITECH has combined the functions of AC source and current source into one, customers can test more easily, and there is no need to purchase different power supplies for different types of test equipment, thus saving test costs.

Current Source Mode Advantages

The upgraded current source mode has strong adaptability and can work in multiple modes such as single-phase, reverse-phase, AC and AC+DC. At the same time, its maximum voltage can reach700V, which can control the output current more accurately, further improving the stability and precision of the product. This also makes ITECH AC sources better adapt to various high-voltage and high-current applications, improving the performance and reliability of the circuit.

The current source mode also has more abundant and diversified functions, which can meet various types of conventional and dynamic test requirements. Among them, the normal function issued to simulate conventional current output, while the LIST function can edit custom waveforms to meet the simulation needs of engineers for complex current waveforms. In addition, this current source mode also has comprehensive waveform editing and customization functions, which is convenient for users to customize the current waveform they need.

AC+DC mode, AC20A+DC30A, 50Hz

Current limit 10A, enter the current loop

The upgraded IT7800 high-power programmable AC power supply, IT7900 regenerative grid simulator, and IT7900Phigh-performance regenerative grid simulator have stable and reliable output incurrent source mode, and can simulate various loads, such as laser drivers, LEDs, motors, etc. Users can quickly deploy and use related test functions such as frequency scanning with a maximum frequency of 2400Hz, charge and discharge, and AC impedance to improve test efficiency and accuracy. At the same time, it is also equipped with a variety of safe and reliable protection mechanisms to ensure the safety of the equipment and optimize the design of the system.
