The three phase Static Transfer Switch is the second option 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. When the main power supply fails, the load Read More

STS (Static Transfer Switch): Extremely fast (usually ≤5 milliseconds). Achieving essentially uninterrupted operation. ATS (Automatic Transfer Switch): Slower (usually tens of milliseconds to several seconds). noticeable flickering of lights occurs during switching.Applicable Loads STS: Used for cap Read More

Statement 1: STS adopts the "first break, then close" technology to achieve short-term switching Statement 2: STS adopts the "close before break" technology to achieve uninterrupted switching Statement 3: Why does the STS switching time still take 4-8 milliseconds if it is a "close first, then disc Read More

The single phase Static Transfer Switch 16amp 25amp 32amp 40amp 45amp 63amp 80amp 100amp 125amp 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 th Read More

To summarize ATS and STS in one sentence, it would be: ATS is a "circuit level" power switch, while STS is a "waveform level" power switch. Simply put, ATS is the "power level dispatcher", while STS is the "guardian of the load level".ATS (Automatic Transfer Switch) ATS is a basic and widely used po Read More
