The DTP series motor controller (hereinafter referred to as the motor protection controller) is a motor protection device developed by our company for the failure of low-voltage motors in various applications; it is a highly cost-effective, stable and reliable, integrated relay protection, Low-voltage motor protection device integrating measurement, control and communication. The controller collects three-phase current, three-phase line voltage, ground current and other data, and compares these data with the setting information of various protection functions recorded by the controller. When the protection action conditions are met, the relay output is driven to achieve protection The purpose of the electric motor. The controller is composed of two parts: the controller body module and the display module (large-screen Chinese LCD). The controller body module can run independently to realize measurement function, protection function, motor start/stop control function and
