Elgar SL Series power sources are wide range, solid-state linear amplifiers that convert the incoming line to low distortion, stable sine wave power. These solid-state frequency changers are benchtop/19" rackmount units that can be driven over their full voltage and frequency ranges by fixed, variable or programmable
plug-in oscillators. The SL offers overload and overtemperature protection, can operate continuously at up to 150% rated capacity, and provide up to three output voltage ranges.
