The HD35 USB load resistor is a compact and powerful test tool for developers, technicians and quality testing in the field of mobile power supplies. With a load capacity of up to 35 W, the device is ideal for testing power supply units, USB chargers or power banks under realistic load conditions. The current consumption can be precisely regulated via an integrated trimmer from 0.25 to 5 A - flexibly adjustable depending on the application.

An easy-to-read, four-digit LCD display shows the current amperage in real time. In addition, two buttons allow the load to be conveniently switched on and off without disconnecting the test setup. The integrated simulation of common fast charging standards such as QC2.0 (5 V, 9 V, 20 V), QC3.0, FCP and AFC (9 V) allows practical tests of modern charging electronics.

Reliable operation is ensured by a temperaturecontrolled high-performance fan with 8000 rpm, which keeps the compact electronics within the optimum temperature range even under continuous load. In addition to the classic USB-A, the HD35 also supports micro USB and USB-C - ideal for use in modern test environments.

At just 84 × 41 × 28 mm and a weight of 52 g, the device is light, mobile and quick to use - perfect for laboratories, service operations or use in production.
