(1) Green (HG, GL) What it means: stands for Safety, Normal, Readiness (i.e., an indication under safe operating conditions or the readiness of a mechanical device to start). Function: It is often used to indicate the state of equipment ready to start, all auxiliary components are in a state of preparation for operation, and various parts ...

What are the uses of air switches 1. The air switch is an important electrical appliance in the low-voltage distribution network and power drive system, which integrates control and a variety of protection functions. In addition to completing contact and breaking circuits, it can also generate short circuits to circuits or electrical equipment. Severe...

1 The contact is overheated Contact heat is mainly caused by the current flowing through the contact, and there is power loss between the contacts (such as contact resistance loss, arc energy loss). It is normal for the contacts to heat up, but severe heat (overheating) is a malfunction. The main ...

During the "Twelfth Five-Year Plan" period, China deepened reform and opening up and accelerated the transformation of economic development mode. Transformation and upgrading is the only way for the sustainable development of the machine tool industry, and the top priority of the industry's transformation and upgrading is to enhance the market competitiveness of high-end CNC machine tools. Exhibitors will take advantage of the CCMT ...

1) Ambient air temperature: The upper limit of ambient air temperature is +40°C, the lower limit of ambient air temperature is -5°C, and the average value of ambient air temperature for 24h does not exceed +35°C 2) Altitude: The altitude of the installation site does not exceed 2000m. 3) Atmospheric conditions: Atmospheric relative humidity in the surrounding air ...

1. The circuit breaker is equipped with an arc extinguishing device, so the circuit breaker can be operated with load, but it cannot operate the current of the load. The disconnector does not have an arc extinguishing device, and it can operate places where the load current is less than 5A, but it is generally not suitable for operation with load. 2. And the circuit breaker ...

Uses: X42 series limit switches can be widely used in various types of mechanical equipment, automatic assembly lines and other light and medium load occasions, can detect the object action state, such as presence and absence, movement position, end of stroke, etc. Overview: The switch is mainly composed of switch operating parts, ...

1. After opening, establish a reliable insulation gap to separate the equipment or line that needs to be overhauled from the power supply with an obvious disconnection point to ensure the safety of maintenance personnel and equipment. 2. According to the operation needs, change the line. 3. It can be used to divide and combine small currents in the line, ...

1. Differences in appearance Although these two types of switches seem to be very familiar, but there are still differences, half of the leakage protection switch is the same as the air switch, and the other half is not, it is equipped with a test jump button and a recovery button, which are not available in the air switch. 2 ...

1. Check the key points: 1) Whether the voltage at point B is 310V. 2) Whether the 15V voltage is normal. 3) Whether the voltage at point C is greater than 14V. 4) Whether the SS terminal of (8) pin IC6 is higher than 10V, whether the SD terminal of pin (10) is lower than 0.6V, and whether there is a square wave transmission at pin 13 and pin 14 ...

1. Wiring The design requirements of wiring are very strict in the design of switching power supplies, and they must be done well to pass the test. If the designer does not handle the wiring work in the early stage of design, there will be great safety hazards in the future electricity consumption. So here I recommend you to buy a switching electric ...

1. Change the reference current of the feedback module Regulating the reference current is the most basic way to regulate the output current of a switching power supply, and it can usually be achieved by rotating a potentiometer or toggling a switch. Changing the reference current allows the magnitude of the feedback current to be compared with it, so as to control the switch ...

The so-called PNP and NPN proximity switches are for the type of DC three-wire proximity switch output transistor, and even though many proximity switch output stages use MOS transistors, they are still called the same. Differences: PNP type proximity switch: The type of proximity switch output transistor is P...

According to the different ways in which it is installed It can be divided into outdoor disconnector and indoor high-voltage disconnector. Outdoor disconnector refers to the disconnector that can withstand wind, rain, snow, filth, condensation, ice and heavy frost, etc., and is suitable for installation on terraces. According to the different structures of its insulating pillars ...

First, first place the dual power supply on the adjustment table, and the phase wire and the neutral wire (neutral line) are docked in place, and can not be connected wrongly. Second, after the line is connected, it is necessary to check the installed line, and then turn on the main switch of the debugging station to turn on the common and standby working power supply. Three, when the double ...

The working process of the main circuit of the linear power supply is that the input power supply is first converted into a DC power supply by the pre-regulated circuit after the initial AC voltage regulation, and then the linear adjustment element is finely adjusted under the intelligent control of the control circuit and the monolithic microprocessor controller, so that the ...

1. Use less plastic switches The switch is composed of a panel, a current carrier, a nozzle and a base, etc., and a good switch is mostly made of stainless steel inlay, which is safe and anti-electric shock. On the contrary, most of the inferior switches are made of plastic, although they are insulated, they are prone to leakage and flammability, and potential safety hazards will occur. 2 ...

Merit: Good stability: Linear power supply can provide stable output voltage and current, which is very suitable for circuits and equipment that require high power supply accuracy.
