Intelligent multi-functional dual power control

Function Description 

The controller is used in double power conversion switch, the main components are selected large-scale Harvard structure microcomputer chip, is a stable and reliable work performance, less foreign components, high engaged in dry resistance performance, anti-misoperation, anti-dead, anti-coding, anti-data loss, low temperature rise, maintenance-free, no adjustment components, the adjustment of pure software to complete. Hardware and software have reached excellent level.

Controller by the keyboard bit input and (LCD) large liquid product display, the common power (N), backup power (R) three-phase four-wire (over-voltage, under-voltage, phase failure, loss of voltage, power failure) and other synchronous detection. Higher than 115% of the rated working voltage value is judged as overvoltage, lower than 80% of the rated working voltage value is judged as undervoltage, anti-misoperation function is designed for sudden changes in peak working power. Standby alarm (can also be artificially closed). The microcomputer makes the corresponding processing of the detection result, and then the execution instruction, the processing result is displayed on the (LCD). Give the user a good man-machine interface. Initialization of the default automatic common working mode.

Power (overvoltage, undervoltage, phase failure, loss of voltage, power failure) and other abnormal conditions, the microcomputer line detection into the double division, after a delay (OS305BM factory set to 35), and then put into the backup power work, (if the power supply at the same time there is an abnormality. Enter the double division state, with the power supply back to normal are priority work), the backup power supply (overvoltage, undervoltage, phase failure, loss of voltage, power failure) and other abnormal conditions, while sending "roar, beep" alarm sound.

◇Self-commissioning and self-recovery: When the common power supply is abnormal, it will be delayed by double points. Then put into the standby power supply to work. When the common power supply is detected to be back to normal, it automatically returns to the common power supply from the standby.

◇Self-injection without self-recovery: When the common power supply is abnormal, it is delayed by double points and then put into the standby power supply, and when the common power supply is detected to return to normal, it does not automatically return to the common power supply.

◇Grid and grid; the controller detects the common and standby power supply from two grid transformer voltage.

◇Grid and power generation: the controller detects the commonly used and the original from the grid transformer, the backup original from the self-provided generator set voltage. When the common power supply is abnormal, it can automatically start the generator set, and when the generator set voltage returns to the normal range value, it will automatically close the generator starter.

◇When the common power supply is detected to return to normal, it will automatically return to the common power supply from the standby, fire fighting (EPS) 24V: This machine adopts the electronic fire fighting function, which has the characteristics of stable performance and reliable work compared with the traditional electromagnetic sub-excitation fire fighting, AC and DC (15-30V) voltages can work, and there is no positive or negative DC. The working current (30MA) is about.

◇High-performance low-power microcontroller with Harvard structure
