Automatic Transfer Switch(ATS Switch)
It is automatically connected to the standby power supply through the dual power switch when the power is suddenly cut off so that our operation will not stop and can continue to operate. The purpose of the dual power automatic switch is simply to use all the way standby, when the common power sudden failure or power failure, through the dual power switch, automatically put into the standby power, (small load standby power can also be powered by the generator) so that the equipment can still operate normally.
The automatic switch is called ATS for short. An ATS consists of two parts: a switch body and a controller. The switch body has the difference between PC (Power Contactor) and CB (circuit breaker).
1. PC Class: integrated structure (three-point type)
It is a special switch for dual power supply switching, with a simple structure, small size, self-interlocking, fast conversion speed (within 0.2s), safety, reliability, and other advantages. It needs to be equipped with short-circuit protection appliances.
2. CB class: ATS equipped with overcurrent release
Its main contact can be switched on and used to break the short circuit current. It comprises two circuit breakers and a mechanical chain, with a a short circuit protection function; The controller is mainly used to detect the working condition of the monitored power supply (two channels). When the monitored power supply fails (such as any phase break, undervoltage, voltage loss, or frequency deviation), the controller issues action instructions and the switch body automatically converts from one power supply to another with the load. The capacity of the standby power supply is generally only 20% to 30% of the capacity of the commonly used power supply.
The ATS controller generally has the function of selecting non-important load. The controller also comes in two forms: one consists of a traditional electromagnetic relay; The other is digital electronic intelligent products. It has the advantages of good performance, adjustable parameters, high precision, high reliability, and easy of use.
