Do you regularly need to perform back-to-back testing on batteries or electric drives? Perhaps you have a limited mains infrastructure which is restricting your test capabilities? Then we could have the perfect solution.
The LAB-MOBI is a multi-channel bidirectional power system which operates as a programmable DC source or DC load. 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 models have been released including:
New 2 Channel Systems
- 2× 600V/200A, max 60kW taken from/recycled to grid
- 2× 300V/200A, max 120kW taken from/recycled to grid
- 2× 300V/600A, max 120kW taken from/recycled to grid
- 2× 300V/1000A, max 120kW taken from/recycled to grid
New 4 Channel Systems
- 4× 600V/200A, max 60kW taken from/recycled to grid
- 4× 300V/200A, max 120kW taken from/recycled to grid
- 4× 300V/600A, max 120kW taken from/recycled to grid
Models up to 1000V/1000A/650kW are available. Outputs up to 1.3MW are possible when operating systems in parallel. Each LAB-SCUBI provides a highly stable output of ≤0.1% rms F.S. for both current and voltage, ideal for powering sensitive DUTs.
Energy can be recycled between channels above the system's nominal power. For example the 4 channel 600V/200A/60W system highlighted above can sink up to 120kW from a source, such as a battery pack, from channel four and use the energy directly across the other three channels. The unit's remaining capability can still be used across the other 3 channels to and from the grid. This feature is particularly useful for sites which have a limited incoming grid infrastructure.
The high dynamics of the LAB-SCUBI 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.
