1. Product Overview
The HAT360 series dual power ATS controller is designed with a microprocessor as its core, enabling precise measurement of two-way voltages. It makes accurate judgments and controls outputs in response to voltage abnormalities such as overvoltage, undervoltage, overfrequency, underfrequency, loss of phase, and reverse phase sequence. This controller facilitates automatic and intelligent transfer of the Automatic Transfer Switch (ATS), integrating an OLED display and digital communication for enhanced human-computer interaction. It is an ideal solution for dual power ATS applications.
