Output Power: 120VA Frequency Range: 45 Hz-5 kHz Output Voltage Range: 0-130, 0-260 Line Regulation: ±0.25% at ±0.7 power factor Continuous duty at 100% of rated capacity Elgar 121B 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 121B offers overload and overtemperature protection, can operate continuously at up to 150% rated capacity. The linear design of the B Series provides a highly regulated, clean sine wave, making these units ideal for linear loads in general purpose test applications as well as for Automatic Test Equipment systems and avionics testing.
