AC220V Dual Power ATS Automatic Transfer Switch 2P 4P High Current
—FENIGAL Manufacturer & OEM of ATS FMQ3G-F series in China
Product Overview(hereinafter referred to as the switch) is a switch that continues to supply power in case of emergency. The switch consists of a load switch and a controller, and is mainly used to detect whether the main or backup power supply is normal. When the main power supply is abnormal, the standby power supply will start working immediately, thus ensuring the continuity, reliability and safety of the power supply. The product is designed for home rail installation and is specifically used in the PZ30 distribution box.
The switch is suitable for emergency power supply systems with 50Hz/60Hz, rated voltage 400V and rated current 100A or less AC power. It is widely used in various occasions where power outages cannot be sustained. (The main backup power supply can be the power grid, or start the generator set, battery, etc., the main backup power supply is determined by the user).
Structural features and functions
The switch is small in size, beautiful in appearance, reliable in conversion, easy to install and maintain, and long in life. The switch can realize automatic or manual conversion between common (I) power supply and standby (II) power supply.
When the common (I) power supply loses power (or phase), the switch automatically switches to the standby (II) power supply, and when the common (I) power supply returns to normal, the switch automatically returns to the common (I) power supply. The switch has a short conversion time (milliseconds) in the automatic state, which can realize uninterrupted power supply to the power grid.
Manual conversion: In the manual state, the switch can convert between the common (I) power supply and the standby (II) power supply manually.
