This Static Transfer Switch Power Panel (STS-PP) automatically transfers
critical loads from a primary power source to an alternate power source in
the event of interruption or abnormal conditions. Designed using siliconcontrolled rectifier (SCR) power-switching elements, the STS-PP transfers
the critical load between power sources in less than 1/4 cycle upon loss
of source – more than 10 times shorter than traditional electromechanical
switches – appearing seamless to even the most sophisticated loads.
Accomplishing rapid transfer without cross-connecting power sources, the
STS-PP ensures that no damage can occur to either power source. This
also allows for transfer between two dissimilar power sources – a feature
far superior to mechanical open-or closed-transition automatic transfer
switches.
The STS-PP has precision digital sense and control circuits that do not
require calibration or adjustments (no potentiometers). The sensed analog
signals are converted to digital format before being interpreted. All operational parameters are set digitally.
The STS-PP has dedicated logic for the critical interpretation and switching operations. This dedicated logic ensures fast and predictable operation at all times. A microcontroller performs the system level functions
such as operator interface (control panel), operating parameter setup, and
remote monitoring and control.
The STS-PP is designed to mount in a switchgear panel or power
distribution unit that has the necessary circuit breakers for bypass and
isolation.
