Rohrer GmbH
Measurement and System Technology
ROHRER has been designing and manufacturing measurement equipment and systems for a wide range of applications for over 20 years. Through our associates we can offer complete, complex systems, realising the most exacting standards. Key areas are power amplifiers up to 20kW for actuators and sensors, signal recording, preparation and saving, especially where high sample rates are required.
Advantages of linear regulated power amplifiers
- Wide frequency range eg. DC to 1,4MHz
- Very low distortion
- Precise zero axis crossing
What are arbitrary amplifiers?
Arbitrary amplifiers serve to amplify analogue signals with any chosen curve form
What are the key features of the HERO® precision power amplifiers?
HERO® precision power amplifiers are 4 quadrant amplifiers for high speed applications and exact zero axis crossing. Capabilities are:
- Frequency range DC ... 1,4MHz
- Output power to ca. 20kW
- Output voltage to 1200VDC
- Output current to 2500Aeff
Where are HERO® precision power amplifiers used?
- simulation and analysis of high power including real mains supplies
- stimulation of Helmholtz coils and piezo actuators
- control and regulation of magnetic fields
- engineering and quality control of magnetic materials
- calibration of measuring transducers and distance relays
- superconductor research
- programmable dynamic sinks
What distinguishes a HERO® precision power amplifier?
HERO® precision power amplifiers are designed to be adaptable to the task in hand. They can be optimized to suit the assignment, for instance, with regard to control, supervision, regulation characteristics, and power dissipation capabilities.
