Dual power automatic switch features
Double power switch is a power switch that automatically switches to another power supply because of power failure. Generally, double power switch is widely used in high-rise buildings, computer rooms, residential areas, hospitals, airports, docks, fire, metallurgy, chemical industry, textile and other important places that do not allow power failure. Dual power automatic switching switch […]
What is the main function of frequency converter? Where does it apply?
Frequency converter is indispensable in our daily life, so what is the main role of frequency converter? Where are they all applied? First of all, the frequency converter is a power control equipment of AC motor by changing the working power frequency of the motor using frequency conversion technology and microelectronics technology. The most basic function […]
What are the common limit switches?
Limit switch variety, its model is not clear here; Limit switch is commonly divided into mechanical and electronic induction type, photoelectric type three, although they work in different principles, but its role is exactly the same, are used to detect the mobile electrical equipment operating position of a device. The mechanical limit switch, commonly known as […]
Frequency converter frequent fault alarm causes and countermeasures
In order to ensure that the frequency converter can operate stably in the hot summer and reduce the unnecessary unexpected downtime caused by improper maintenance or poor site operating environment, let’s take a look at the countermeasures to solve the corresponding problems. Cause one: If the ambient temperature is too high, the temperature of the […]
The reason for the large-scale application of micro switch is analyzed
Micro switch is a micro contact interval and fast moving mechanism, with the specified stroke and the specified force for switching action of the contact mechanism, covered by the shell, the external drive rod of a switch, because the switch contact spacing is relatively small, so the name of micro switch, also known as sensitive […]
