Tianyi switch - the use and function of air switch

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 ...

Conventional domestic travel switch LX19-001/111 in the LX19 series, LXK3-20S/T in the LXK3 series, JLXK1 series JLXK1-111/411/511 in the conventional travel switch are the most representative.

1. When the power is cut off for some reason and the power supply cannot be restored in a short period of time, the backup power supply must be enabled: (1) Cut off the circuit breakers of the mains power supply (including the circuit breakers of the control cabinet of the power distribution room, and the mains power cut-off of the dual-power switching box), and pull the double-cast anti-backing switch to the side of the self-provided power supply, ...

1. How to wire the button switch with a light, there are a total of five binding posts on the button, and now you can only measure how to connect the power cord, but the light is on and I don't know how to connect. Answer: This situation is relatively simple, this kind of switch should be two terminals connected to the lamp, the other 3 terminals are switches, find out ...

1. If it is installed on metal, a certain space must be ensured to avoid interference between the proximity switch and the metal other than the detection object, resulting in failure. The metal parallel to the sensing surface must be 3 times the sensing distance from the sensing surface. The metal around the shaft of the proximity switch must be outside the cylinder, close to ...

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. 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. In addition to the short-circuit protection function of the fuse, the air switch can also realize the overload protection of the circuit. 2. The fuse is a one-time protection device, which must be replaced once it is blown and is very troublesome, so its reusability rate cannot be compared with the air switch. ...

(1) The disconnector should have an obvious disconnection point, which is easy to identify whether the electrical appliance is disconnected from the power grid. (2) There should be reliable insulation between the disconnect points of the disconnector, that is, there should be enough distance between the disconnect points of the disconnector to ensure that it can work reliably under harsh climatic conditions, and ...

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 ...

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 ...

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, ...

Unmarked/Z: Inductive/inductive self-diagnosis C/CZ: Capacitive/Capacitive Self-Diagnosis N: NAMUR safety switch X: Analog F: Hall V: Reed type J: Threaded cylindrical B: Cylindrical Q: Angular cylindrical shape ...

1) When there is a power outage for any reason and the power cannot be restored in a short period of time, the backup power supply must be activated 1. Cut off the circuit breakers of the mains power supply (including the circuit breakers of the control cabinet in the distribution room, and the mains power supply cut-off of the dual power switching box), and pull the double-cast anti-reverse switch to the side of the self-provided power supply to ensure that the power supply is protected.

1. The current value of the air switch is too low, and the load power is greater than the rated power of the air switch. 2. The load joint is not firm, and the joint is not compressed. 3. If there is a short circuit in the line, check whether the electrical plug is dry. 4. The line is aging and leaking, resulting in both the live wire and the neutral line.

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.

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 ...

Q1: What is the difference between P switch and T switch? A: P switch is a load isolation switch, mainly used for the opening and isolation of the main circuit load, only 3P and 3+N, can add auxiliary contacts; The T-switch is a multi-function switch with a wide variety of contact sequences, modular contact units, which can ...

The meaning is different, the scope of application is different, and the role is different. Air opening C represents the current, and the D model represents the power. The scope of use is different. If it is a household electricity, the air switch of the C model is generally chosen. The role is different. Type C it is used for home lighting use, Type D is suitable for ...

(1) Before operation, check that the circuit breaker (switch) is in the opening position accordingly to prevent the isolation switch from being pulled and closed with load. (2) There is a locking device to prevent misoperation between the knife switch, the grounding knife switch and the switch, and the reverse operation must be carried out in order. If it is locked and cannot be operated, ...
