Specifications for Triple Output Power Conditioner, designed for the Varian Trilogy™ System, Clinac™ iX, or Silhouette™, with On Board Imager™.
1.0 SCOPE
This specification covers the electrical characteristics of the Transtector Power Conditioner which provides clean regulated power for the entire Trilogy™, IX, Silhouette System or Varian High Energy Linear Accelerators with On Board Imager™ (OBI).
2.0 GENERAL
The Power Line Conditioner consists of a front access power cabinet incorporating an all copper, multiple tapped, triple shield isolation/regulation transformer. The ultra low output impedance of the transformer in conjunction with the electrostatic shields assures precision hospital grade performance with excellent noise and transient attenuation. Independently controlled inverse parallel electronic switches for each of the 7 taps per phase provide tight regulation over a wide input range. Linear devices are used for line synchronization to prevent phase shift errors normally associated with simple CT zero current crossing acquisition. The microprocessor control accurately selects the correct tap to maintain the output no greater than ± 2.0 % of nominal in a typical installation, correcting for voltage disturbances within one cycle. Digital processing technique provides fast and accurate regulationwithout output voltage over or undershoots.
