The Schneider inverter model generally reflects the rated voltage, rated power, and load requirements of the inverter (heavy load is still light load type). Here are 2 examples: Example 1: Schneider inverter model: ATV71HD11 ...

In addition, it is unscientific to select the inverter body alone, without considering whether the inverter selection and capacity matching are appropriate. ...

Because the impact of foreign electrical products on domestic electrical equipment is relatively large, now Schneider inverter equipment occupation is facing a big technical promotion, taking inverter as an example, the national connotation of inverter shopping mall domestic brand and foreign brand, regardless of technology, processing and manufacturing, industrial design and other aspects are still ...

1. Why is the inverter used for fan and pump loads to save energy? According to the basic law of fluid mechanics, it can be seen that the fan pump load is a typical square rotation load, and its primary feature is that the speed n has the following relationship with the torque T and the load power P: T∝n2, P∝n3. ...

1) Survey and research method. The investigation and research method is to understand the obvious problem phenomena through "seeing", "listening", "smelling", "touching" and "asking"; After visiting the operator, understand the cause of the failure; A common way to help find the fault point after asking others or consulting information ...

The air switch is divided into the upper inlet line and the lower inlet line of the power supply, 1 is - 3 is + 2 is + 4 is - when the upper line is inlet, 2 is + 4 is - This is related to the internal trip curve. DC circuit breaker is used for DC system operation method conversion or fault removal ...

(1) Protective button: a kind of button with a protective shell that can prevent the internal button parts from being mechanically damaged or people touching the live part, and its code is H. (2) Dynamic break button: Under normal conditions, the switch contact is a kind of button that is turned on. (3) Dynamic button: Under normal conditions, the ...

After the maintenance function of the inverter is caused by the operation of the problem, it will trip immediately, and the fault code will be displayed together, and the tripping alarm indication circuit of the peripheral inverter will send out an audible and visual alarm to remind the operator to clean up the problem in time. Inverter hopping ...
