CH9720 Electronic Load Tester

Product Detail

CH9720 series electronic load adopts high-performance ARM processor and high-speed measuring circuit to ensure the accuracy of measurement; 4.3 inch TFT color screen supports Chinese-English interface, cooperates with carefully designed guide menu, and operates well; display information is rich and comprehensive, intuitive and convenient; it has a higher display resolution of 0.0001, which can more accurately monitor the voltage and current details of the products under test; some models have USB memory interface, which can save settings files conveniently and interoperate settings between instruments.

The instrument is equipped with RS232C interface, with a rich set of SCPI instructions, which can be easily connected to the computer for real-time data acquisition and instrument control. 　

 

Hlavní vlastnosti:

  • 360V wide voltage input, wider scope of application, can be widely used in non-isolated power supply testing
  • The display parameters of 4.3 inch TFT color screen are comprehensive, clear and intuitive, and support the Chinese and English operation interface.
  • Software update of U disk, data saving and screen capture function of U disk (CH9720BU/9720CU)
  • Higher dynamic response speed for high-speed power supply testing.
  • Standard RS232 interface, no special cable can be connected with the computer.
  • Customers can purchase standard RS232 to USB interface at will, and do not need to buy manufacturer-specific connectors to save costs for users.
