Delixi regulator output voltmeter keeps swinging back and forth, and sparks occur at the carbon brush, and the problem phenomenon and cause analysis
1. The contact pressure between the carbon brush and the coil plane is too small
2. The carbon brush is severely worn
Delixi voltage regulator sometimes announces the mechanical rotation noise and motor rotation sound phenomenon and cause analysis
Voltage adjustment is made frequently due to changes in the input voltage
Delixi voltage regulator can stabilize the voltage, but the deviation of the voltage stabilization value and the cause analysis
1. Voltage trimmer potentiometer displacement
2. The voltmeter reading is not accurate
Analysis of the unstable voltage phenomenon and causes of Delixi voltage regulator

Instrumentation overhaul method - Delixi
Contrasting method
The specific method is to let the problematic meter and the normal meter operate under the same conditions, and then detect the signals at some points and compare the two sets of signals measured, if there are differences, you can conclude that the fault is here. This method requires maintenance personnel to have considerable knowledge and skills.

Inverter application skills - Delixi
1. Shielded wires should be used for signal lines and control lines, which is beneficial to avoid disturbance. When the line is long, for example the distance jumps 100m, the conductor cross-section should be enlarged. The signal line and the control line should not be placed in the same cable trench or tray with the power line, so as not to disturb each other, it is best to place it through the pipe, ...

Changes in the control mode of the inverter - Delixi inverter
In the process of practical speed regulation, an ordinary AC power supply with adjustable frequency can not meet the requirements of speed regulation and control of asynchronous motors, and must also take into account the effective use of the motor magnetic field, the pressing starting current and the desired torque characteristics, such as low-frequency torque characteristics.

Delixi spare parts replacement cycle
1. Cooling fan (2-3 years)
As long as the inverter is in use, the cooling fan has always been running, so the cooling fan is generally a short-service life accessory, generally after the use of the cooling fan for 2-3 years, the bearings, balls, motors, etc. of the fan are seriously worn, and they need to be replaced.

Resistance quantization circuit exerts resistance to the flow of current – Delixi
We are able to compare the values of resistance and hose diameter (conductance vs. practical diameter). When it comes to metal wires, this analogy works well. Small-diameter wires have a higher resistance than large-diameter wires made of the same metal.
The standard unit of resistance is ohms, there are ...

Delixi integrated voltage regulator knowledge
The role of a voltage regulator is to convert an unstable DC voltage into a stable DC voltage. The integrated voltage regulator has a wider and wider range of applications due to its advantages such as small size, good voltage regulation performance and perfect maintenance function. There are two types of integrated voltage regulators: linear power supply regulators and switching power supply regulators.
