Tianyi switch - precautions for high-voltage load switch

1. Increase inductance and output capacitance filtering According to the formula of the switching power supply, the current fluctuation in the inductor is inversely proportional to the inductance value, and the output ripple is inversely proportional to the output capacitance value. Therefore, increasing the inductance and output capacitance can reduce ripple. In the same way, the output ripple is the same as the output ...

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. 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 ...

The dual-power automatic transfer switch is mainly used in the emergency power supply system, which automatically switches the load circuit from one power supply to another (standby) power supply switching appliance to ensure the continuous and reliable operation of important loads. Therefore, the dual-power automatic transfer switch is often used in important places of electricity consumption.

First, the characteristics are different 1. Limit switch: The limit switch has the characteristics of small size, multiple functions, high precision, adjustable limit, strong versatility and easy maintenance, installation and adjustment. 2. Proximity switch: The proximity switch has the characteristics of a limit switch, and at the same time has the sensing performance.

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 ...

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. 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. 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. The basic conditions for the use of low-voltage isolation switches (1) The altitude does not exceed 1000 meters; (2) The ambient temperature is not higher than +40°C and not lower than -40°C; (3) The relative humidity is not more than 85% (relative to +20±5°C). 2. The low-voltage isolation switch is not suitable for the following ...

First, the repair method The maintenance of a switching power supply can be carried out in two stages (1) When the power is cut off, it is "Look, Listen, Listen, Measure" Look: Open the power box, check whether the wire is disconnected, look inside the power supply, and find that the PCB substrate of the power supply is scorched or the components are cracked.

1. Install the dual power transfer switch with the power supply to ensure the correct access of the power supply. 2. Adjust the handle of the dual power transfer switch to the "automatic" position, so that the power supply will automatically detect the state of the other power supply, when one of the power supplies fails, the other power supply will ...

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 ...

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. Pay attention to stability When adjusting the output current of the switching power supply, the stability of the circuit must be ensured, otherwise there will be current fluctuations, disturbances and other phenomena, which will affect the normal operation of electronic equipment. Therefore, it is necessary to perform a ...

The load switch and combination electrical appliances are mainly composed of frames, isolation switches (the current limiting fuse of the combination is on the isolation switch), vacuum switch tubes, grounding switches, spring operating mechanisms, etc. The product has compact structure, small size, long life, strong closing and breaking ability, and simple operation and maintenance.

Generation and transmission of electromagnetic interference There are two ways of electromagnetic interference transmission: one is conducted transmission and the other is radiated transmission. Conducted transmission is a complete circuit connection between the interference source and the sensitive equipment, and the interference signal is transmitted to the receiver along the connected circuit.

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. What are the common faults? Answer: The common faults of the disconnector are: (1) The contact part is overheated. (2) Porcelain insulation damage and flashover discharge. (3) Refuse to pull and close. (4) Wrong pulling and closing. 2. The overheating of the contact part of the disconnector during operation is caused by ...

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.
