performance

Working principle of intelligent system
a. The controller simultaneously detects two voltages, and judges any voltage higher than 110% (adjustable) of the rated value as overvoltage, and any voltage lower than 85% (adjustable) of the rated value as undervoltage (or loss) voltage. The microcomputer control circuit makes logical judgments on the above detection results, and the processing results are sent to the electric operating mechanism through a delay (reliable) circuit to drive the corresponding instructions to open or close the circuit. The above detection results can be displayed on the LCD screen of the intelligent automatic controller panel, or connected to the computer through a serial port and controlled by software for the user to find the cause. The user can restore the fault line in a short time and restore the dual power supply to its original state

Intelligent automatic controllers are divided into three types according to their control functions

Self investment and self recovery (R) are applicable to power grids and power grids The intelligent automatic controller automatically switches between two power sources, namely the common power source and the backup power source. In normal state, the standby power source supplies power. When the common power source fails or is abnormal (overvoltage, undervoltage, undervoltage or undervoltage of any phase), it automatically switches to the backup power source for a set (adjustable) delay time. When the common power source returns to normal, the set (adjustable) delay time automatically returns to the common power source for power supply. When the backup power source fails or is abnormal (overvoltage, undervoltage, undervoltage or undervoltage of any phase), the controller triggers an alarm for the permanent or backup power source

Specifications and Technical Parameters
1. Self investment without self recovery (S) is applicable to power grids and power grids
The automatic controller that automatically switches between two power sources (i.e. common power source and backup power source) without self recovery Any abnormality occurs in any power supply (overvoltage occurs in any phase voltage)
When under voltage or phase loss occurs, it automatically switches to a normal power supply after a set delay, but cannot automatically recover when the abnormal power supply returns to normal
When used in the power grid and power generation system, the conversion time should be set at 15 seconds. The automatic controller of the power grid and power generation automatically controls the two power sources of the power grid and power generation
Switching, when the grid voltage is below 85% of the rated voltage, a power generation command is issued through a power generation delay command (output through a set of normally open and closed contacts) When the generated voltage reaches 85% of the rated voltage, the load circuit is first disconnected from the power grid, and the secondary load is unloaded (output through another set of normally open and closed contacts) through unloading instructions. Then, the generated power supply is connected with a delay through conversion After the power grid returns to normal (reaching 85% of the rated voltage or above), the intelligent controller will automatically disconnect the load circuit from the power source and switch to the power grid for power generation based on logical judgment
When the commonly used power supply is abnormal, the microcomputer will detect the current preset working status (manual, automatic, self resetting, non self resetting) and whether the backup power supply is normal to decide whether to switch and start the backup
Using power supply, the system load is powered by a backup power source
