STS

TOP PERFORMANCE FOR HIGH POWER CRITICAL LOADS. High-performance STS, up to 3000A with extremely short transfer time (<=4ms). Its overload capability enables its use also in heavy duty applications. Thanks to its internal redundancy and oversizing it guarantees maximum reliability.

Features: 
​

  • Voltage and frequency continuous monitoring and synchronizing

  • Extremely rapid automatic transfer (<= 4ms) thanks to continuous synchronization, without sources connection

  • No transfer under short circuit after the STS, to keep up the current until the correct protections work

  • Continuous check of the SCR proper working and back feed protection

  • Dual bypass, one per source, to achieve total sources independence in case of maintenance

  • Maximum reliability thanks to redundant internal power supplies and cooling, plus oversizing of the neutral (2x)

  • Front access for easy maintenance

  • Bottom connection as a standard, top connection possible to simplify installation in any condition

  • Wide communication offer as a standard: dry contacts, RS 232, RS485

  • Use of Circuit Breakers, for best protection in all conditions

Options:
​

  • Isolation transformer

  • Plug-in breakers

  • Panel builder version

  • Additional dry contact board

  • 4-pole configuration

  • Operation without neutral
