The California instruments Model 100ITC Power Amplifier is a solid state, high performance, low distortion power source that provides up to 1000 VA output when used with the proper plug-in oscillator. The Model 1001TC Power Source is illustrated in Figure 1-1. Full power output is available in two different voltage ranges and over the frequency range from 45 Hz to 5 KHz. These full power voltage ranges are: 1) 110 to 130 volts rms for normal single phase 115 volt applications· and for three phase 208 to 225 volt line-to-line applications. 2) 220 to 260 volts rms for normal single phase 230 volt applications and for three phase 208 to 260 volt applications where open delta operation is acceptable. For two phase and three phase operation, at least two power amplifiers must be combined together with the applicable multi-phase oscillator. Two power amplifiers will provide a total of 2000 VA two phase power (Model 20Ö0TC/2-2), or 2000 VA of three phase power (Model 2000TC/2-3D) in the open delta configuration. Three power amplifiers will provide 3000 VA of three phase power in the wye configuration (Model 30Ö0TC/3-3).
