Static transfer switch STS 300

three-phasesingle-phase

Three-phase and single-phase static transfer switches for seamless load transfer in dual path power systems. • Rugged design and high reliability • Solutions up to 3000 A • Optimized system configuration for ICT applications • Customization for harsh environment and specific applications Benefits • Total control over load transfer: continuous source monitoring and robust management logic guarantee disturbance free power transfers to downstream critical loads. • High overload capability: industrial derivation design providing high overload capability and high fault current management. • Enhanced safety: redundant control logic and embedded backfeed protection for complete system and operator safety. • Minimum maintenance costs: full front accessibility to all components and high material quality extremely reduce servicing. Features • Continuous monitoring of voltage and frequency and automatic instant transfers for secure power switching without cross connection between sources. • Short circuit transfer inhibit for robust load protection. • SCR fault detection and backfeed protection for maximum upstream safety. • Dual manual bypass for complete source independence during maintenance. • True oversized neutral (2x In), redundant cooling with monitored fans and redundant (3x3) internal power supply in all system control boards for top product reliability in high availability applications.
