Even if it is not the current trend, it can illuminate everything, from our homes to public places to the indicator lights on our electronic devices. However, with the technology advancing more and more each year, Led lighting has allowed for more flexibility in design, greater efficiency in use and a host of other benefits that affect our daily living. This article is to tell you why choose high quality and suitable LED indicator light.

UPS is an uninterruptible power supply with an energy storage device. It is mainly used to provide an uninterrupted power supply to some devices that require high power stability. What is the reason for the loud noise of the UPS? How to deal with it? Fans, inductors, and transformers will make noises when the UPS is working. When the UPS is working, generally a slow beep is a small fault (which can be automatically recovered), a rapid beep is a major fault (recoverable), and a long beep is a major fault. Let us learn together what are the reasons for the loud noise of UPS?

How much power does the UPS have? How to choose UPS power? The sum of squares of UPS active power and reactive power is equal to the square of apparent power. Generally, the active power is about 60%-70% of the apparent power. Confirm the power of the equipment loaded by our UPS, and then you can confirm the power of the UPS. In general, ATO.com recommends that the load power accounts for 30% to 80% of the UPS power.

When there is mains power, the UPS output is normal, but when there is no mains power, the buzzer beeps for a long time and there is no output. Fault analysis: It is judged from the phenomenon that the battery and inverter are partially faulty, and can be checked according to the following procedures.

Human machine interface refers to the field where people and machines contact or interact with each other in information exchange and function. This joint surface includes not only the direct contact between point, line and surface, but also the action space of long-distance information transmission and control. So how does HMI communicate with PLC?

The uninterruptible power supply is a very important power supply device in our daily life and work, and it can even be said to be ubiquitous. So which type do we usually see? What are the differences between these different types of ups in their work? Let's take a look. Uninterruptible power supplies are usually divided into three types, namely offline, online, and online interactive. These three types of uninterruptible power supplies are very common in work and production.

Terminal block is a kind of accessory product used to realize electrical connection. The simple structure of the terminal block can play an extremely important connection role, the cost is low, and it is the best assistant for signal transmission.

UPS is a device that contains energy storage. It is a constant voltage and constant frequency uninterruptible power supply with an inverter as the main component, which can solve the problems of power failure, low voltage, high voltage, surge, noise and so on of the existing power, and make the computer system run more safely and reliably. Now ATO UPS has been widely used in computers, transportation, banking, securities, communication, medical, home, industrial control, etc.

A synchronous motor is an AC motor that rotates at a synchronous speed by interacting with the excitation magnetic field of the DC power supply and the rotating magnetic field of the armature to generate torque.

Household UPS is to provide power supply for computers and other related products in the family, just like conventional UPS is different from industrial UPS. When choosing a home UPS uninterruptible power supply, you should choose genuine brand products. For those who do not know about various professional power matching and power supply times, you can directly consult ATO customer service. ATO.com is a professional R&D, production and manufacturing UPS company, and the manufacturer ships directly.

While the motor brings more convenience to production and life, its energy consumption cannot be ignored. In the face of the rising cost of purchasing mechanical products and the gradual increase in energy consumption, high-voltage motor maintenance manufacturers will recommend choosing energy-saving motors, or transforming the original motor, these are good choices for enterprises to save costs.

Vacuum circuit breakers are used for switching purposes in high voltage (HV) applications. Vacuum circuit breakers are more efficient, smaller and less expensive. VCB breakers have a much longer lifespan than conventional circuit breakers and require little maintenance. VCB (Vacuum circuit breakers) are ideal for typical utility and industrial applications.

UPS, also known as an uninterruptible power supply, is a constant voltage and constant frequency uninterruptible power supply with the energy storage device and inverter as the main component. It mainly provides uninterrupted power supply to a single computer, computer network system or other power electronic equipment. When the mains input is normal, the UPS will stabilize the mains and supply it to the load. At this time, the UPS is an AC mains voltage stabilizer, and it also charges the battery inside the machine. When the mains power is interrupted (accidental power failure), the UPS will immediately supply the 220V AC power to the load by inverting the power of the battery in the machine, so that the load can maintain normal operation and protect the software and hardware of the load from damage.

An induction motor is similar to a poly-phase transformer whose secondary is short circuited. Thus, at normal supply voltage, like in transformers, the initial current taken by the primary is very large for a short while. Unlike in DC motors, large current at starting is due to the absence of back emf. If an induction motor is directly switched on from the supply, it takes 5 to 7 times its full load current and develops a torque which is only 1.5 to 2.5 times the full load torque. This large starting current produces a large voltage drop in the line, which may affect the operation of other devices connected to the same line. Hence, it is not advisable to start induction motors of higher ratings (generally above 25kW) directly from the mains supply.

A screw feeder is a mechanism that uses a rotating screw blade, usually inside a tube, to move liquid or granular materials. They are used in many bulk handling industries. Screw conveyors in modern industry are often used horizontally or slightly inclined as an efficient way to convey semi-solid materials including food waste, wood chips, aggregates, grains, animal feed, boiler ash, meat and bone meal, municipal solid waste, and Many others. Screw conveyors can move material horizontally inclined or vertically. They are used for feeding, dispensing, collecting or mixing, and can be equipped with heating or cooling when transferring using appropriate covers and gaskets, they are easily dust or weatherproof and rodent proof.

A rotary switch is a switch operated by rotation. These are often chosen when more than 2 positions are needed. A rotary switch consists of a spindle or "rotor" that has a contact arm or "spoke" which projects from its surface like a cam. It has an array of terminals, arranged in a circle around the rotor, each of which serves as a contact for the "spoke" through which any one of a number of different electrical circuits can be connected to the rotor. The switch is layered to allow the use of multiple poles; each layer is equivalent to one pole. Alternatively the rotation can be limited to a fraction (half; third etc.) of a circle and then each layer can have multiple (two; three etc.) poles.

Today we will introduce what is a voltage sensor and its working principle and function. We hope that after reading this article, you will have a clearer understanding of voltage sensors.

A voltage sensor is a sensor that senses the voltage being measured and converts it into a usable output signal. In various automatic detection and control systems, voltage sensors, often need to track and collect high-speed changing AC and DC voltage signals.

How long can UPS equipment supply power? UPS manufacturers have industrial UPS power supplies with 10 minutes, 30 minutes and other types. Is the UPS time longer the better? In fact, it is better to control the UPS time within 8 hours. Why is this?
