Voltage, current and servo controllers
Controllable power supplies from 10W to 12kW

SERVOWATT power electronics supplies tailor-made power amplifiers and controllable power supply units with specific properties to industry, research and development in batches of as little as one.

We manufacture high-precision permanent and controllable current and voltage sources to customers’ specifications with a typical high-performance bandwidth of 20 to 100 kHz and a slew rate of 5 to 50 V/μs. These amplifiers have linear output stages for the highest degree of precision with infinite resolution and absolute EMI interference elimination. We can offer PWM devices with an L/C filtered output for all cases where higher power requirements cannot be met with linear regulators. Bipolar versions are the standard, unipolar versions require prior consultation.

Power operational amplifiers and controllable power supplies have 4 control inputs for all kinds of control engineering tasks, for example to add or subtract several control signals or to operate as an autonomous servo system. Extremely fast and precise controls for force, acceleration, speed, temperature and generally all physical dimensions and their processes can be stabilised in this simple way.
