Altitude: The altitude of the installation site does not exceed 2000m. Atmospheric conditions: Atmospheric relative humidity at ambient air temperature of +4 ...

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 ...

1. No output, the fuse is normal This phenomenon indicates that the switching power supply is not working or has entered the protection state. First of all, it is necessary to measure whether the starting pin of the power control chip has a starting voltage, if there is no starting voltage or the starting voltage is too low, it is necessary to check whether the starting resistance and the external components of the starting pin are ...

First, the principle is different 1. Class Cb automatic switch is an electronic product that converts one or more load circuits from one power source to another 2. PC-level automatic transfer switchgear is an electrical appliance that converts one or several load circuits from one power supply to another. ...

JD series warning light is Tianyi electrical appliances in the field of signal control launched high-performance products, once launched, it has won the unanimous favor of customers, products in the design, manufacturing, quality control and other aspects of the company's quality system has always been under the strict testing and supervision of the company's quality system, to ensure that each product ...

1. First of all, it is necessary to select the appropriate input voltage specification; 2. Choose the right power. In order to extend the service life of the power supply, it is necessary to select an additional type with 30% of the rated output power. 3. Consider the load characteristics. The load added is a motor, bulb or capacitive load, and the current at start-up ...

1. Protection The most important role of the limit switch must be its protection effect, the limit switch is also known as the travel limit switch, which is mainly used to control the stroke of mechanical equipment and limit protection. In practice, the travel limit switch is installed in a pre-arranged position, and the travel limit switch is installed in a pre-arranged position.

Conversion conditions: The purpose of requiring dual power supplies is to complete the automatic and reliable conversion of dual power supplies under "specific" circumstances. This "specific condition" is the conversion premise of the dual power supply, or the conversion condition, which is the primary consideration for choosing the dual power supply. A. In the event of a power failure ...

1. First open all the packages of the newly bought limit switch, confirm that the parts in each package are not missing and complete, and then discharge all the parts in turn. 2. Then open the body part of the limit switch, as long as you loosen the screws with a screwdriver.

In the design of switching power supply, the physical design of the PCB board must be proper, otherwise it may cause excessive electromagnetic interference and lead to unstable power supply. 1. The design process from the schematic diagram to the PCB should be rigorous and perfect: the establishment of component parameters ...

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 ...

1. The design is usually simple and straightforward 2. Works well in almost any industrial environment 3. It has high accuracy and repeatability 4. Low-power devices 5. High inductance load can be switched 6. Used to switch multiple loads 7. Simple installation ...

1. It can isolate the power supply, have obvious disconnection points, and is mostly used for fixed high-voltage equipment. 2. It has an arc extinguishing device and a certain opening and closing speed, and can pass the normal working current and the specified short-circuit circuit in the closing state. 3. It is strictly forbidden to turn on and off the circuit with load.

1. The high-voltage load switch can be broken with load and has the function of self-extinguishing arc, but its breaking capacity is very small and limited. 2. The high-voltage isolation switch is generally not able to break with load, there is no arc extinguishing cover in the structure, and there is also an isolation switch that can break the load.

The scope of use of the travel switch (limit switch). The range of use of travel switches (limit switches) is very wide, so what is the effect of travel switches (limit switches)? The position switch (limit switch) refers to the maintenance of the micro switch from external forces, oil, water, gas, ...

(1) First of all, when operating the isolation switch, you should first check that the circuit breaker of the corresponding circuit is indeed in the disconnected position to prevent the load from pulling and closing the isolation switch. (2) When the line is stopped and the power is transmitted, the isolation switch must be pulled and closed in order. During the power failure operation, the circuit breaker must be pulled first, and then ...

How to use the indicator color correctly? 1. The indicator light (also known as the signal light) is mainly used to attract the attention of the operator or instruct the operator to carry out a certain operation in the way of bright indication, and as an indication that a certain state or instruction is being executed or has been executed. 2. General ...

1. Common air switch models in the family Common family models: DZ series, C16, C32. C40, C80, C100, C120 and other products, of which C represents the starting current, such as: C32 means that the starting current is 32A, which can drive a 6500 watt water heater, C40 ...

daily life There are many aspects of the use of limit switches, and it is found in many electrical appliances. So what effect can such a simple switch have? It is first and foremost a chain maintenance effect. The most common example is its use in washing machines and tape recorders (video recorders). ...
