CEDRAT TECHNOLOGIES has developed several types of piezoelectric actuators and magnetic actuators especially adapted to Active Control of Vibration, Active Control of Noise, Active Isolation, Active or semi-active damping, Shock absorbers, etc.
Some actuators, such as piezoelectric actuators, are available as full standard or customised actuators. Other actuators, such as new magnetic actuators are available as customised solutions.
CEDRAT TECHNOLOGIES has also developed complete systems including actuators, sensors and control electronics for vibration control. A famous example is the damping of ski vibrations. In this application, vibrations up to 80mm amplitude are actively cancelled using the CEDRAT TECHNOLOGIES’ actuators and control electronics.
Objective
The multi-channel Linear Amplifier LA24 is designed as a low noise, high bandwidth linear amplifier for finely driving magnetic actuators, such as Voice Coil, Moving Iron Controllable Actuators or Limited Angle Torque Actuators from CEDRAT TECHNOLOGIES.
Description
The Linear Amplifier LA24 is designed as a low noise linear amplifier which displays a signal to noise ratio of 90 dB and requires a standard bipolar stabilized DC source (+/- 48V). The Switching Converter SC24 provides the stabilized bipolar DC source from the main and is inserted in the rack. Both boards are implemented on a printed circuit board compatible with the standard CEDRAT TECHNOLOGIES rack system. Therefore, the standard configuration is a RK42F+SC24+LA24-1.
The multichannel Linear Amplifier LA24 is compatible with controllers from CEDRAT TECHNOLOGIES:
– The UC45 real time controller, as a mezzanine board into the LA24 board
– The UC75 real time controller, as an additional board in the rack, with extended functions.
Several mechatronics functions can be built, ranging from positioning, scanning, stabilization
