Wenzhou Kinee Electrical Co., Ltd. is one of the most reliable manufacturers and suppliers of dual power automatic transfer controller in China. We warmly welcome you to wholesale dual power automatic transfer controller for sale here from our factory. All customized products are with high quality and competitive price.
Product Introduction
KNTN530N Dual Power Automatic Transfer Controller is composed of the core microprocessor, which can precisely measure 3-phase/single phase voltage of 2 ways, make accurate judgment on abnormal voltage (power lost, over/under voltage, over/under frequency, loss of phase, phase sequence wrong), and control ATS to transfer after delay is expired.
This Dual Power Automatic Transfer Controller is suitable for NO Breaking ATS and ONE Breaking ATS. When #1 power is abnormal, the Dual Power Automatic Transfer Controller will send signal to start genset after the "#1 abnormal delay" has expired. "Three remotes" (remote control, remote measurement and remote communication) functions can be implemented with the help of RS485 communication port, making this Dual Power Automatic Transfer Controller an ideal choice for reliable power switching applications.
