Pre-stroke - indicates the distance or angle at which the actuator on the limit switch must move before tripping the switch contact Operating Point - Indicates the position of the actuator when the switch contact is moved to the working position Release Point - Indicates the position of the actuator when the contact returns to its original state Differential - ...

(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. Repeated short-circuit test ◆ Test instructions The output of the module is short-circuited in various input and output states, the module should be able to achieve protection or retraction, repeated short-circuits, and after troubleshooting, the module should be able to automatically resume normal operation. ◆ Test Method a ...

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 ...

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). ...

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. 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 ...

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. When closing, first of all, attention should be paid to check that the circuit breaker that can be connected to the dual-power automatic transfer switch is indeed in the opening position, and then quickly operate the risk isolation switch to close it (whether the enterprise adopts manual management agency or leveraged financial institution personnel operation), but ...

(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 ...

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. 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 ...

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. 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.

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...

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. Principle The contact system of the transfer switch consists of several moving contacts embedded in the insulated housing with a static contact base and a movable support. The moving contact is a double-break butt contact bridge, which turns the circuit on or off with the rotating shaft of the rotating shaft attached to different positions. Positioning...

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...

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) 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 ...
