Product Description
Product Overview
The 3kV/2000kW electronic load product can simulate inductive or capacitive load conditions, such as those encountered during the startup or normal operation of high-power motors or generators. It automatically adjusts the load according to specified load curves and features programmability, making it ideal for load testing of power supplies or power systems. Thanks to its four-quadrant operation capability, the product can also recover braking energy generated during load tests back into the power grid.
Rated power: 2000 kW
Rated voltage: 3000Vac
AC-side voltage range: Three-phase 3000 VAC
