Reset the time and date, power off 10 minutes and then start to see if the clock can be real-time timing.
The output power in the grid parameters is set to 0%. If the grid connected power needs to be reduced, this parameter can be modified to the required percentage.
No, the photovoltaic input can only be used to charge the battery and cannot generate electricity to load.
No, there is no internal outpuit terminal for wake up generator.
GD5000 comes standard with built-in PID regulator, which can realize closed-loop control.
The full range of medium voltage GD1000/GD2000/GD3000 products can provide two-quadrant or four-quadrant products.
GD5000/3300V products are designed with multi-level power units connected in series. GD3000/3300V adopts a three-level topology design scheme, mainly comparing and replacing ABB ACS1000 series and Siemens GM150 series.
As the single-phase motor contains the starting capacitor, the start-up capacitor is designed to generate a 90-degree phase difference between the primary and secondary windings of the single-phase motor, resulting in a rotating magnetic field to rotate the motor. The size of the starting capacitor is generally designed according to the frequency 50Hz, but when the single-phase motor frequency control, the frequency will not always work at 50Hz, it is difficult to produce rotating magnetic field, the common method is to remove the single-phase motor start and run Capacitor, the use of two-phase control method.
After adopt the method of removing the capacitor, the software algorithm improvements, it is necessary to ensure that limit the starting current, but also to ensure that the starting torque, so the final output voltage than the direct start voltage amplitude is low, resulting in load capacity decreased.
It mainly has two type of brake type which are permanent magnetic brake and eletro-magnetic brake. For permanent magnetic brake, the heating is small, accuracy is high, no noise but it's expensive; For electro-magnetic brake, the heating is big, accuracy is low, it has noise but it's cheap.
