Do you know the Matters Needing Attention when using Power Relay?

As a Power Relay Manufacturer, share with you.
Power Relay are commonly used devices in automatic control systems. They are used to connect and disconnect circuits to form automatic control and remote control circuits. Whether it is the core component of a relay signal system or the interface component of an electronic or computer signal system, it plays an important role. The same is true for power relays. Today we will analyze those matters needing attention when using small high-power relays.

Power Relay 
1. Rated working voltage or rated working current: This refers to the voltage or current required by the coil during high-power operation. The construction of one model is generally the same. In order to adapt to the circuit application of different voltages, a large model usually has multiple rated operating voltages or rated operating currents, and is distinguished by specifications.
2. DC resistance: This refers to the DC resistance of the coil. Some product specifications give the rated working voltage and DC resistance. At this time, the rated working current can be obtained according to Ohm's law. If the rated operating current and DC resistance are known, the rated operating voltage can also be obtained.
3. Pull-in current: It refers to the minimum current that a small high-power relay can generate a pull-in action. In actual use, to make small high-power relays reliably attract, the given voltage can be equal to or slightly higher than the rated operating voltage. Generally not more than 1.5 times the rated working voltage. Otherwise it will burn the coil.
4. Release current: It refers to the maximum current that the small high-power relay produces in the release action. If the current of the small high-power relay in the pull-in state is reduced, when the current is reduced to a certain level, the small high-power relay returns to the state when it is not energized. This process is called the small high-power relay release action. The release current is much smaller than the pull-in current.
5. Load: It refers to the voltage or current allowed by the small high-power relay contacts. It determines the size of the small high-power relay that can control the voltage and current. In applications, small high-power relays with small contact loads cannot be used to control high current or high voltage. For example: The contact load of the Y3F small high-power relay is 0.02A × 12V, so you cannot use it to control the 220V circuit on and off.

How to Buy a Good Relay?

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
