SmartPSU3 provides three fixed relay-switched regulated and monitored low-power voltage outputs. As it has one positive and one dual positive/negative supply, it fits well for mixed signal audio applications, such as DACs, where dual analog supply and single digital supply are required. All channels use linear regulators for low-noise output.
