The LAB-GSSH is an innovative DC high power system. Operating in quadrants 1 & 4 the LAB-GSSH can operate as either a DC Source or DC Electronic Load. When load testing the excess sink energy is not wasted as heat. Instead the output it is inverted from DC to AC and synchronised back to the grid.

The modular format means the system can be reconfigured or expanded to meet changing test requirements. In-built dedicated system comms allow users to switch between various set-ups. Parallel, series or matrix configurations are all possible. Each slave module can operate independently providing unrivalled flexibility. Various standard and optional interfaces are available for remote control. A number of parameters are user adjustable including internal resistance as well as voltage and current slopes.

Complex waveforms can be created and implemented by the embedded function generator. Standard sine, square and sawtooth shapes can be plotted against time for voltage, current and power outputs. High system dynamics allow fast switching of quadrants. The bidirectional characteristics make the LAB-GSSH ideal for testing high power automotive applications.

Behaviour and stability of complex on-board electric vehicle power systems can be tested under a variety of programmable conditions. Previously recorded test data can be imported and replicated so that a real track driving test can be accurately simulated in the lab. A dedicated battery cycling GUI is available which allows users to emulate standard and complex battery charge/discharge algorithms. Live test data can be recorded, reviewed and replicated. Systems are available up to 3MW. Lab racks and flight case integrations are available on request. Did you know...

The LAB-GSSH is comprised of our LAB-GSS units.
The LAB-GSSH mains ReGen capability allows the unit to return the load power to the grid where it would usually be dispensed as heat. Feeding the grid in this manner is compliant with EN50438 and VDEO126. Its ER G59-3 testing meets the requirements for connection to UK mains.
