PID 110 – Versatile PID Regulator
- Ideally suited for side-of-fringe laser stabilization
- P, I, D parameters individually adjustable
- Variable total gain
- High Voltage output e.g. for driving piezos
- Automatic ReLock feature
The PID 110 is a proportional integral differential regulator for the SYS DC electronics system and can be used for various control tasks, such as stabilization of the laser frequency to the edge of an atomic resonance or a transmission of a cavity. Both high and low voltage actuators (Piezos, laser temperature, …) are supported. Its flexibility makes the PID 110 into a general purpose PID for scientists laboratories.
