Information
The California Instruments Model 503T is a solid state, high performance, low distortion power source that provides up to 500 VA the three phase power when used with the proper California Instruments Oscillator. The Model 503T Three Phase Power Source is illustrated in Figure 1- 1. Full power output is available in five different voltage ranges and over the frequency range from.45 Hz to 5 KHz. The output voltage range is normally determined at the factory prior to shipment of the unit, however it can be accomplished in the field, if required. The full power ranges are; 1) 23, 4 to 30 volts rms line-to-neutral in a three phase output configuration. This provides 40* 5 volts to 52 volts rms line-to-line at 167 VA per phase (500 VA total). 2) 35. 1 to 45 volts rms line-to-neutral in a three phase output configuration. This provides 60. 6 volts to 78 volts rms line-to-line at 167 VA per phase (500 VA total). 3) 58. 5 to 75 volts rms line - to-neutral in a three phase output configuration. This provides 102 volts to 130 volts rms line-to-line at 167 VA per phase (500 VA ..........total)...,....................................................................................................... 4) 105 to 135 volts rms line-to-neutral in a three phase output configuration. This provides 182 volts to 234 volts rms line-to-line at 167 VA per phase (500 VA total). 5) 105 to 135 volts rms single phase output at 500 VA. The serial number tag, located on the rear of the Model 503T Power Source, indicates the output voltage range which the unit is wired for at the time of shipment.
