200A Three-Phase Static Transfer Switch - Industrial Dual Source Transfer
STS-3P-200A
The Hannibal STS-3P-200A is a static transfer switch built to maintain power availability by transferring critical loads between two AC sources.
Overview
The Hannibal STS-3P-200A is a static transfer switch built to maintain power availability by transferring critical loads between two AC sources.
It continuously monitors source voltage and frequency, checks synchronization and transfers the load to the available or prioritized source within milliseconds, helping protect sensitive equipment from interruptions.
Key features
- 01Nominal current: 200A.
- 02Transfers critical loads between two independent AC sources without mechanical moving parts.
- 03Synchronized and asynchronous transfer support with selectable asynchronous transfer enable/disable.
- 04Selectable source priority via front panel and 2x16 LCD display.
- 05Thermal fuse and overvoltage protection at source inputs.
- 06Designed for data centers, telecom, industrial processes and sensitive critical power loads.
