Static Transfer Switch(STS) is an automatic static switching equipment designed to transfer critical loads between two independent AC power sources with a transfer time to ensure uninterrupted power availability when a power outage occurs. When the first circuit fails, STS automatically switches to Read More

STS(Static Transfer Switch) in mobile data center, is an automatic static switching equipment designed to transfer critical loads between two independent AC power sources without interruption or with a transfer time to ensure permanent power availability when a power outage occurs in order. A Mobile Read More

STS(Static Transfer Switch) in UPS system, is an automatic static switching equipment designed to transfer critical loads between two independent AC power sources without interruption or with a transfer time of less than a cycle (20ms) to ensure permanent power availability when a power outage occu Read More

The single phase Static Transfer Switch offers true redundancy and exceptional high reliability for automatic switching system of the power supply. Under the normal working state, the main power supply is within the normal voltage range, and the load is always connected to the main power supply. Whe Read More

The function of a static switch: It can only work normally in parallel when the frequency and amplitude of two AC power sources are the same. When a fault occurs in one of the AC power sources, a balanced current will be generated between the two power sources, causing a change in the output voltage Read More

In many important occasions, the reliability of the load of electricity consumption is very important. In order to improve the reliability of the load, the general power supply system adopts dual power supply, such as dual main power, one main power and UPS. However, the more reliable method is to u Read More

Automatic Transfer Switches (ATS) are designed to transfer AC power supply between independent one-phase or three-phase.Automatic transfer switch helps in offloading traffic. It also helps in firewalling, detecting intrusion, analyzing performance.NASN RACK TYPE ATS (Automatic Transfer Switch) featu Read More
