What Should Power Relay Do When There Is Insufficient Voltage?

Once the voltage applied to the coil is insufficient, the Power Relay will not work, or the operation will be unstable, which will cause the durability of the contact to decrease or the contact point such as welding to be blocked. In particular, in a large motor or the like, when the power is turned on, the voltage applied to the relay coil sometimes drops at the moment of a load operation in which a large inrush current is generated. If the relay is operated in a low voltage state, even if it is a vibration or shock value within the specifications specified in the specifications and catalogues, the relay may malfunction. Therefore, apply a rated voltage to the coil of the relay. For fluctuations in the power supply voltage, apply a voltage to the coil that each relay can fully operate. If a voltage is applied to the coil that does not allow the relay to fully operate, the coil will be abnormally heated, causing the coil to burn out. In addition, if a motor, a solenoid, a transformer, etc. are connected to the same power supply line as the operating circuit of the relay, when those devices operate, the power supply voltage is lowered, the contact of the relay is vibrated, causing the contact to burn out, welding, or Can not protect themselves. In particular, when a small transformer is used and when the transformer does not have a sufficient capacity, such a use method may occur if the wiring is long or the wiring for household use or shops is thin. In the case of a similar failure, use a synchronous oscilloscope to properly adjust the voltage change, and take appropriate countermeasures and convert to a DC circuit.
We have relays such as T90 Relay, CE Relay, etc. If you have any questions, please contact us.

How to Buy a Good Relay?

图片
As a  Power Relay Manufacturer , I often meet some customers who say that the quality of your relay is still ok, it is more expensive. Some customers say that I want good quality and cheaper prices. Here, we give everyone a generalization. In fact, the good or bad of Power Relay, 60% is determined by the contacts, reeds, outer casing, thin wire, base, etc. of the relay, and 40% of them are assembled in the relay. Determined in the process. Think about it, if the relay parts are poor, how well the relays are assembled on the production line, and will not make good  PCB Power Relays . Just like a chef, you give him poor raw materials, how good his cooking skills are, and he can't fry good dishes. Therefore, if you have a piece of money and a good quality, it will be more expensive. Power Relay So how do we see the relays are good and bad? If you are interested in researching and taking two different brands, you can see the difference if you study it carefully. Take our relay

What Are The Methods For Relay Debugging?

What are the methods for  Relay Debugging ? The following small series explains for you: 1. Before using the relay, check whether there is any damage caused during transportation. Set the relay to the first setting point, turn the movable system to the magnetic pole direction by hand, and then release it. The movable system should be turned back to the original. Position until the stop. 2. When the relay is re-adjusted, it must be guaranteed: a, the axial movement of the movable system is between 0.15 ~ 0.25mm; b. The air gap between the moving piece and the magnetic pole should be uniform. Under any action, the moving piece and the magnetic pole should not touch each other; c. During the action, the movable system must not be stuck in the middle position; d. When the pointer is rotated from the first scale to the maximum scale, the loops of the hairspring shall not touch each other; e. When the contact is in the open position, the total air gap between the static and dy

Analysis Of The Development Prospects Of Relay Industry

In the past ten years, China's information industry has developed rapidly at a rate three times that of other industries. The communications and automotive industries are also moving forward at a rapid pace. At the same time, the home appliance industry has begun to emerge as an important demand driver. With the overall improvement in the quality of life of Chinese products, more and more consumers are interested in new or upgraded appliances, which in turn stimulates the demand of  Power Relay . According to the forward-looking report of China's current relay industry market foresight and investment planning analysis released by Prospective Industry Research Institute, the use of relays in these industries is considerable. With the development of these industries, it will undoubtedly promote the further expansion of the relay market. In 2010, although the number of relay outlets decreased, the value of exports increased, indicating that the added value of the export relays
