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

NASN STS is a kind of switch of fast load transfer, its transfer time is less than 4ms and it is applicable to the real load transfer in the same phase and the ... Read More

STS(Static Transfer Switch), 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).The STS consists of Silicon controlled rectifiers (SCR’s), control & sensing c Read More

Static Transfer Switch(STS) is a static electric device, designed to automatically transfer charge to a standby power source connected to its input when there were an earlier disruption and to reverse without interrupting the server room charge. Static Transfer Switch(STS) It is completely static, a Read More
