Static Transfer Switches – STS
MAXIMUM AVAILABILITY FOR ALL CRITICAL APPLICATIONS
STS havehigh performance STS, up to 3000A with extremely short transfer time (<=5ms). Theiroverload capability enables its use also in heavy duty applications. Thanks to their internal redundancy and oversizing it guarantees maximum reliability.
Perfect for:
Applications industrial
Data centers
IT applications

Features
- Provides redundant power supply to equipment with a single input by managing two power sources if parate and independent.
- Maximum automatic transfer rate between two sources: ≤5ms 63 A version, ≤4ms 100 A to 1250 A version.
- Maximum protection: in the event of a downstream short circuit, it automatically inhibits the transfer, preventing damage to both sources.
- Maximum continuity of connected loads due to total independence of sources and internal redundancy on all components including bypasses, power supplies, cooling systems etc.
- Direct front access to all components and separate dual manual bypass guarantee easy and safe maintenance.
- Continuous input voltage and frequency monitoring to allow safe switching without source cross-overs.
- Real-time SCR status detection and backfeed protection for maximum upstream system safety.
- Circuit breakers for improved protection in all conditions.
- RS232, RS485 ModBus ports, dry contacts and slots for optional communication card.
Main options:
- Additional dry contact board.
- Operation without neutral.
- Isolation transformer.
- Cable entry from above.
- 4-pole configuration with switched neutra
