Wenzhou Kinee Electrical Co., Ltd. is one of the most reliable manufacturers and suppliers of 4p solar power dual power automatic transfer switch in China. We warmly welcome you to wholesale 4p solar power dual power automatic transfer switch for sale here from our factory. All customized products are with high quality and competitive price.

The KNQ1 Series 4P Solar Power Dual Power Automatic Transfer Switch is a newly developed household micro power switch primarily used to detect whether the main power supply and the backup power supply are functioning normally. In the event of an abnormality in the main power supply, the backup power supply activates immediately, thereby ensuring continuity, reliability, and safety of power supply. This product is specifically designed for household rail mounting and is dedicated for use in PZ30 distribution boxes.

The KNQ1 Series 4P Solar Power Dual Power Automatic Transfer Switch is suitable for emergency power supply systems with a frequency of 50 or 60 Hz and a rated voltage of 400V AC. As a reliable 4P Solar Power Dual Power Automatic Transfer Switch, it features a robust structure, reliable switching, convenient installation and maintenance, and a long service life. This 4P Solar Power Dual Power Automatic Transfer Switch is widely used in various situations where power outages are unacceptable and can be operated either electrically or manually. The ATS consists of the Transfer Switching Equipment (TSE) and a controller.

1.Manual/automatic operation

ATS can guarantee the performance of power generation and power failure during circuit operation, but for manual operation, ATS cannot guarantee the above perform -ance due to the difference of power generation and power failure speed or operator. During manual power generation and power failure, excessive silver alloy loss may occur. Therefore, when all power supplies are cut off to check and maintain the operating system and contacts, it is only necessary to pull the selector switch to the manual position. Under normal circumstances, please pull the selector switch to the automatic position. When operating manually, pull the selector switch to the manual position. After the manual operation is completed, pull the selector switch from the manual position to the automatic position.

2.Control circuit

ATS instantly becomes active. After the conversion is completed, the coil in the control circuit will be disconnected by the internal converter. Under the rated voltage of 80%-110%, the coil can operate normally. Low voltage will cause coil heating and even spontaneous combustion.
