Product Description
Main features:
The new DC Electronic Load ,adopts ARM processor and high-speed sampling AD, the system runs smoothly and handily.
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.
