The SPS20 Cagire is a low-noise power supply based on a linear AC/DC converter. It was first designed to provide a quiet environment to operate our ultra-low noise laser current source (SMC-Series). For this purpose, three SPS20 modules are assembled in a 3U desktop case (SR100 Estélas) to power up to 2 complete
laser diode controllers and their dedicated laser frequency control electronics (SMA– and SMB-Series).
Because they have little to no ability to reject supply variations, many RF subsystems should also benefit from the low-noise features of the SPS20-Series to prevent unwanted side bands and low signal-to-noise ratio.
The SPS20 Cagire’s output is protected against short-circuit using an adjustable current limiter. An overvoltage crowbar is also added on the output to provide ultimate protection of the loads. The SPS20 Cagire can be remotely controlled (on/off) using its dedicated isolated input. For more information refer to the functional block diagram.
