SYS1-100G/250G/630G/1600G/3200G Automatic transfer switch

The dual power automatic transfer switch is a device controlled by a microprocessor, which is used for switching between grid power and grid power or grid power and generator power in the power grid system, so that the power supply can be continuously supplied. The series dual power supply, when the common power suddenly fails or the power is cut off, it will be automatically put into the backup power supply through the dual power supply switch, (the backup power supply can also be powered by the generator under small load), so that the equipment can still operate normally. The most common are elevators, fire protection, surveillance, lighting, etc.

Structure and characteristic

SYS1 series automatic transfer switch is composed of switch is composed of switch body and controller. Adopt the electromagnetic driver, the working power of controller transfer is based on the main power and the standby power. AC220V power supply, without additional source. Switch body have an electrical or mechanical switch instruction as an isolation indicator function.NOTE: For more detail information you wanan know, pls feel free contact with me. Thanks!
Safety protection, cut off quicklyWhen the voltage outgoing line fluctuates, the power can be cut off quickly (less than 2 seconds), and the overvoltage will not be burned.

Copper MaterialAll contacts are made of copper for better conductivity and safety.

Insulated terminal block for safer and safer installation
   A dual power transfer switching appliance is an appliance that transfers one or more load circuits from one power source to another. It consists of one (or several) transfer switching appliances and other necessary appliances, which are used to monitor the power circuit and automatically convert one or several load circuits from one power source to another power source. In the electrical industry, it is referred to as “dual power automatic transfer switch” or “dual power switch”.
