Rackmount Static Transfer Switches for Seamless Power Switching

Standard capacity: 3.5kW - 528kW

Overviews

STS, a static transfer switch, is an automatic two-power-source switching system. Normally, when the main power is within the normal voltage range, the load stays connected to it. STS uses a break-before-make switching method to achieve uninterrupted switching between power sources.
MSTS, a Multiple Spot Temperature Sensor Static Transfer Switch, is a rapid load transfer switch with a minimum transfer time of 3.2ms, suitable for both in-phase and out-of-phase conditions. It can be connected in multiple sets to form an n+1=1 output for enhanced power supply safety.
The RSTS series of STS is designed for A-level computer rooms. It's a high-performance, cost-effective, second-generation rapid transfer switch with new digital technology and a delayed topology for accurate transfer. It offers high protection, better safety and reliability, a user-friendly LCD interface, and RS232 communication for PC connection to monitor its status, adhering to the "Safety First" principle.
