Information:
                                    The California Instruments Model 1503T is a solid state,
high performance, low distortion power source that provides
up to 1500 VA three phase power when used with the proper
California Instruments oscillator. The Model I503T Three
Phase 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. 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) 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 500 VA per phase (1500 VA total).
2) 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 500 VA per phase (1500 VA total).
The serial number tag, located on the rear of the Model
1503T Power Source, indicates the output voltage range which
the unit is wired for at the time of shipment.
Two of the three power amplifiers may be combined with the
applicable plug-in oscillator to provide 1000 VA of two
phase power. In this case, the line-to-line voltage is 1.414
times the line-to-neutral voltage rather than 1. 732 times
the line-to-neutral voltage. Also each of the three 500 VA
power amplifiers may be used independently of one another by
removing the three jumper strips on the rear of the 12 pin
connector and applying the desired input into each amplifier.
