Active and regenerative electronic loads with arbitrary operation

Very robust machines, especially developed for intensive use on production and testing lines, they are also used in research and development laboratories.

Static loads CT series absorb energy from an external source and return it to a DC bus or to the mains grid, depending on model. They work with a wide range of input frequency from DC up to 800Hz (depending on model).
They can be coupled to many of our converters to achieve a complete supply + absorption system.

Type of absorption selectable:
- Constant current
- Constant resistance
- Constant power
- Constant current with arbitrary waveform
In constant current mode the phase shift between applied voltage and current drawn can be set from -90° to +90 ° to simulate inductive and capacitive loads with CosPhi from 0 to 1.
You can put together more single–phase units to assemble multi-phase systems.
