Static Transfer Switch

Automatic Transfer Switch

Description

A microprocessor-controlled system that ensures seamless power transfer between two sources without interruption. It continuously monitors voltage, current, and frequency, switching to the prioritized source when stable, or instantly transferring to the backup if limits are exceeded — guaranteeing uninterrupted power for critical loads.

product overview

Hannibal microprocessor-controlled static transfer switch designed to automatically transfer electrical power from a primary source to a secondary source without interruption, constantly monitors the sources connected to the inputs; checks whether they remain within the current and frequency limits and decides if they are synchronized with each other. If the prioritized source is within the determined limits, the critical load is transferred over to the prioritized source. If the prioritized source is not within the determined limits, the load is then transferred to the other source
which is within the determined limits.

  •  Instantaneous Switching: STS performs rapid switching operations, typically within milliseconds, ensuring continuous power supply to critical loads.
  • No Moving Parts: Unlike mechanical switches, STS operates without moving parts, reducing wear and tear and increasing reliability.
  •  Dual Power Sources: It monitors two independent AC power sources and switches to the backup source seamlessly if the primary source fails.
  • High Availability: Ensures high availability of power for sensitive applications such as data centers, telecommunications, and industrial processes.
  • Protection: Protects equipment from power disturbances and interruptions.
  • Microprocessor Based Control.
  • Thyristor-based Static Transfer Switch.
  • Suitable with Synchronous and Asynchronous Transfer.
  • Selectable Asynchronous Transfer Enable \ Disable.
  • Synchronous Transfer Time: < 5 msec. (¼ cycle at 50 Hz).
  • 4 Dry Contacts.
  • Asynchronous Transfer Time: < 11 msec.
  • Thermal Fuse Protection at Source Inputs.
  • Overvoltage Protection at Source Inputs.
  • 2×16 LCD Front Panel.
  •  Selectable Source Priority via Front Panel.
  • Suitable with 3rd Input Source (Optional).
