Source Changeover Switches
Static Transfer Switches


Safe fast asynchronous source transfers | Very high MTBF (>800,000 hours)
- Wide range of Solid-state Transfer Switches: 16A–1600A
- Fast 1ms to <1/4 cycle synchronous transfers: Ensures no break in power
- Asynchronous transfers allowed
- Smart Algorithm to avoid saturation / high currents when motors, transformers and solenoids are employed or when undertaking asynchronous transfers
- Built-in Transient Voltage Protection: Delivers system reliability and safety
- Very High MTBF ensures long life/minimal downtime: Up to 1,000,000 MTBF (e.g. 800,000 typical)
- MODBUS & SNMP Compatibility: Enables seamless remote management
- Some units have fuseless design: Enhances safety, reliability, and simplifies maintenance
