Product description
Joy-IT JT-HD35 is an electronic USB load for testing USB power supplies. It is designed to verify the performance of USB devices with USB-A, USB-C, and Micro-USB, with loads up to 35 W. The unit combines an adjustable load, real-time display, and active cooling in a compact form factor.
The JT-HD35 can simulate real-world loading on USB outputs and supports a drive voltage of 4–25 V DC. The load current is adjustable from 0.25 A to 5 A. An LED display shows the current voltage (V), current (A), and power (W) during testing. Three status LEDs, push buttons, and a potentiometer are used for setup and control. A temperature-controlled fan (40 mm) ensures the module can handle continuous loads without overheating during extended test periods.

Application:
An electronic load is a tool for engineers and technicians who need to verify the function and performance of USB power supplies and USB outputs on various devices. The ability to simulate different load levels can be used to confirm that a USB charger delivers the expected voltage and reaches its specified rated current (max).
