Tianyi switch - the term introduction of limit switches

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 ...

The socket, lamp head, kitchen, bathroom, refrigerator, air conditioner of each route should be put out separately, and each route should have a separate air switch, high-power rooms, such as kitchens and bathrooms, the line of more than 4 square millimeters should reach 20A, and the general lamp head line should only be 16A, and each line ...

1. The high-voltage load switch can be used as a load switch, which has the effect of self-extinguishing arc, but its breaking volume is very small and very limited. 2. The high-voltage isolation switch generally cannot be used as a load switch. There is no arc extinguishing cover in the structure, and there are also disconnectors that can switch loads on and off, but the structure is different from load switches ...

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 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...

(1) The cost of linear power supply is higher than that of switching power supply at a certain output power point. Therefore, with the development and innovation of power electronics technology, the switching power supply technology continues to break through and innovate.

1. What is the reason why the empty trip cannot be pushed? 1. If the air opening itself is faulty or damaged, the air opening should be replaced with a new one. 2. If the line is caused by a short circuit, the line should be found first, and then reconnected.

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) 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 ...

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 ...

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 ...

First, the characteristics of the load switch A load switch is a switchgear between a circuit breaker and an isolation switch. It has a simple arc extinguishing device, which can cut off the rated load current and a certain overload current, but cannot cut off the short-circuit current Second, the classification of load switches According to the operating voltage ...

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. For vertical installation, the switch frame, closing mechanism, cable sheath, and protective steel pipe should be reliably grounded (not connected in series). 2. Before operation, several no-load opening and closing operations should be carried out, and each rotating part should be free of jamming, closing in place, and there should be enough safety distance after opening. ...

First, the reason for the fault of the induction circuit of the switch button indicator 1. Aging of circuit board: The circuit board of the switch button indicator induction circuit board may be aged if it has been used for too long, resulting in leakage in the circuit, and then the induction failure of the indicator light. 2. Sense ...

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. 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 ...

36V is a safe voltage, but it cannot be used as a standard for dividing high and low voltages. There are two ways to divide high and low pressure: 1. According to the rated voltage: the rated voltage is 1000V and below is called low voltage; The rated voltage of 1000V or more is called high voltage. 2. According to the voltage of the equipment to the ground...

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 ...

It is mainly divided into ATS and STS. STS static toggle switch STS (Static Transfer Switch), also known as static transfer switch. The STS automatically switches to the second channel to supply power to the load after the first channel fails.
