H&H presents the new generation of source-sinks. In a modern design with touchscreen operation, the QL series on the one hand replaces the proven NL series with equivalent model range, and on the other hand offers far more functionality.
As with its predecessor, the standard portfolio offers 2-quadrant models and 4-quadrant models up to 3,600 W, with 2-quadrant devices operating already at negative voltages from -1 V.

Source-sinks combine the functionality of power supply and electronic load and are therefore used wherever both are to be used synchronously, typically when testing energy storage devices, motors, chargers etc.
