Do you regularly need to test high power devices such as batteries or electric drives? Perhaps you need to isolate bidirectional DC components and assemblies in a controlled test environment? Then we could have the perfect solution.

Multi-Channel Bidirectional DC SystemThe LAB-MOBI operates as a DC source or DC load, with two or four independently programmable channels. Each system features constant power, constant current, constant power and internal resistance functionality. As standard the power system operates in battery testing mode. A battery simulation mode is optionally available, providing users with higher capacitance and low voltage dip during current transients.

A selection of new 650kW models have been released, with voltages and currents available up to 1000V/1000A per channel. Each system provides a highly stable output of ≤0.1% rms F.S. for both current and voltage, ideal for powering sensitive DUTs.

The high dynamics of the LAB-MOBI allow users to switch quickly and seamlessly between quadrants. This is particularly useful when performing tests on devices with fast current step changes such as super capacitors and electric motors. A typical time for a 10% to 90% load step in CC mode is less than 1ms assuming an ohmic load.

Each system is built for longevity. The lowest life components being the fans rated at 67,000h and electrolytic capacitors rated at 130,000h/15 years. This ensures that the systems are suitable for constant operation in long term projects.
