Static Transfer Switch (STS)
STS 1 (Single Phase)
The ELSIPOWER single-phase static transfer switch (STS) series provides uninterrupted power transfer for office systems, medical devices, server rooms, network infrastructure and critical electronic loads. By switching quickly, reliably and automatically between two independent power sources, it supports system continuity against power outages, source failures and voltage problems.
- Single-phase input – single-phase output.
- Optional 19" rack mounting.
- Seamless transfer between independent sources.
- Synchronous / asynchronous transfer mode.
