The new QL bipolar four-quadrant power supplies from H&H

TT&MS BV has expanded its power division with the latest QL series from H&H. This QL series is a completely new line of bipolar power supplies with new functionality, which can function in 2 or 4 quadrants depending on the model.

The bipolar power supplies of the QL series have a “SOURCE” and “SINK” mode, which means that the device can be used both as a power supply and as an electronic load. Besides being used as a DC source, the 4-quadrant version is also suitable as an AC source. The QL series can also be used as an analogue amplifier, suitable for capacitive and inductive loads.

Such power supplies are used when testing a wide range of Energy Storage Devices (charge/discharge), motors, chargers or coils. The standard portfolio offers devices with 2 or 4 quadrants up to 3,600 W. A notable feature is the “modulator” with which in CC or CV mode a sine, square wave, triangular or random signal can be modulated. Frequency and modulation depth are adjustable. In addition, the QL series is suitable for determining the internal resistance Ri of a DUT. As a simulator, the QL series models can also be used to program a Ri and to define charge/discharge parameters.

Standard the units can be controlled analogue or remotely via LAN, CAN, RS232 and USB.
