Overview

The SR100 Estélas is a low-noise power supply providing ±15V and +5V and optionally +24V. The SR100 was first designed to provide a quiet environment to operate our ultra-low noise laser current source (SMC-Series). For this purpose, three SPS20 Cagire modules are assembled in a 3U desktop case 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 SR100 Estélas to prevent unwanted side bands and low signal-to-noise ratio.
