![Single phase Static Transfer Switch Single phase Static Transfer Switch]()
The static transfer switch is a product specially designed for key equipment requiring uninterrupted power supply, and a contactless electronic switch device designed to realize mutual backup and quick switchover between two AC power supplies. It allows automatic or manual switchover, and the switchover time is ≤4ms so that continuous power supply to key equipment can be ensured.
Main characteristics
Switchover between two power supplies
It realizes reliable redundant power supply for key equipment.
Automatic selection of better supply
It can select automatically a power supply of higher quality based on parameter setting.
Short switchover time
Switchover time ≤4ms.
High reliability
Digital control
Using 32-bit DSP digital detection and control technology, it is characterized by strong anti-interference ability, high operational speed, high intelligence, and high control precision.
High adaptability
The power supply may be any two AC power supplies with sinusoidal output.
Monitoring management
The indicator lamp panel can give out sound and light alarm upon fault, and RS485 communication and fault dry contact are provided.
Protection function
It has protection against overtemperature, overvoltage, over-frequency, output over-current, and overload (shutdown and automatic restart after 5 minutes in case of overload).
