What are the debugging methods for relays? As a  Power Relay Supplier , let me explain it today. 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 and 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 st

What are the life requirements for power relays? As  Power Relay Supplier  today to explain to you: 1. The relay contact should be able to turn on and off the voltage of no more than 250V, the current is not more than 1A DC sense load (time constant is 5ms), the breaking power is 10W. 2. During the test, touch contacts are not allowed. The speed of the test should be based on no harmful heat accumulation or ion accumulation on the contacts, generally no more than 1 time/s. 3. During the electrical life, the movable system of the relay should be reliably operated and returned every time. The contacts should be reliably connected and disconnected each time (there should be no stable arc between the contacts), that is, the relay is in the electrical life test. There should be 100% reliability. We also have a  Flat Construction Relay  for you, as well as 18v, 48v relays are available for you, contact us, you can find out more about relays.

The  Automotive Relay  has many uses in cars, but the use of relays is basically the same, both for indirect switching. The riders are not very familiar with this, the following  Automotive Relays Factory  will tell you about the role of automotive relays in the car. A relay is an electronic control device that has a control system and a controlled system. It is typically used in automatic control circuits. It is actually an "automatic switch" that uses a small current to control large currents. Therefore, it plays the role of automatic adjustment, safety protection and conversion circuit in the circuit. Automotive relays generally control high-power appliances such as headlights and heater motors. If the switch is directly controlled by the switch, the insurance is easily damaged. With relays, the switch only controls the relay, and the relay controls the consumer, and the relay requires very little current to protect the switch and the line. Automotive relays are use

The  Telecom Relay  works in the same way as a contactor. The main difference is that the main contacts of the contactor can pass large currents, while the contacts of the Telecom Relay can only pass small currents. Therefore, the Telecom Relay is generally not used to directly control the main circuit, but indirectly controls the main circuit by controlling the contactor and other switching devices. In the Telecom Relay protection loop of the power system, the implementation principle of the Telecom Relay varies with the development of related technologies. The relays still in use can be divided into electromagnetic type, induction type, rectification type, electronic type and digital type according to the action principle. According to the physical quantity of the reaction, it can be divided into current relay, voltage relay, power direction relay, impedance relay and frequency relay. And gas relays, etc., according to the role of relays in the protection circuit can be divided in

MK Relay  main product technical parameters: 1. Rated working voltage The rated operating voltage is the voltage required for the coil when the  Automotive Relay  is operating normally. Depending on the model of the Power Relay, it can be either an AC voltage or a DC voltage. 2. DC resistance The DC resistance is the DC resistance of the coil in the relay and can be measured by a universal meter. 3. Pull-in current The pull-in current is the minimum current that the Power Relay can generate to pull in. In normal use, the given current must be slightly larger than the pull-in current so that the Automotive Relay can work stably. For the working voltage applied to the coil, generally do not exceed 1.5 times the rated working voltage, otherwise a large current will be generated and the coil will be burnt. 4. Release current The release current is the maximum current that the Automotive Relay generates to release. When the current in the state of the relay is reduced to a

The working principle of the  Automotive Relay  is to generate a magnetic field after the coil is energized, and then suck in the contact piece of iron to make the circuit path to protect the circuit. The general connection is that the two wires of the coil are one positive and one negative, one of which is connected to the switch. The other wires are connected to the appliance. The Automotive Relay is printed with the four legs 85, 86, 87, and 30. 85 and 86 indicate the coil legs. 87 and 30 indicate the contact pins. 85 and 86 energize the magnets to make the contacts of the 87 and 30 feet. Pulling in and out to achieve the working state, Yuanze Electric believes that 85, 86 feet are connected to the control line, 87, 30 feet are connected to the working line, and 87, 30 feet can be divided into positive and negative. 87A normally closed contact, generally not commonly used, his role is that the relay coil is energized and disconnected. Then, the Automotive Relay can be regarded

The number of  Automotive Relay China  is divided into three major blocks: 1, Automotive Relay product specifications, generally standard DC12V, DC24V, etc. Represents the rated operating voltage of the relay (that is, the voltage applied to the coil end), at this point some manufacturers will use some numbers to represent their internal specifications, such as HT33067 Can ignore it. 2, Automotive Relay load capacity: general standard NO 40A, or NC / NO 40 / 30A, etc., represents the load rated current that can be carried at the contact end, generally refers to resistive load, with light load or inductive load according to the impulse current multiple cut back. 3, Automotive Relay terminals: such as 30 for the movable end, 87 for the normally open end, 87a for the normally closed end, 85, 86 for the coil end, also useful for 1 to 5, 1, 2 for the coil end, 3 for movable End, 4 represents the normally closed end, and 5 represents the normally open end. If you have any questions,

What are the steps for contact repair of power relays? As a  Power Relay Supplier , let's explain it to you: 1. Open the power relay cover and check the contact surface condition. 2. If the surface of the power relay contact is oxidized, the silver contact can be repaired. The copper contact can be smoothed with a slick or a small knife can be used to gently scrape off the oxide layer on the surface. 3. If the contact surface is not clean, it can be cleaned with gasoline or carbon tetrachloride. 4. If there is burn and burn marks on the surface of the contact, the silver contacts may not need to be refurbished, and the copper contacts may be repaired with a slick or a knife. It is not allowed to use sand cloth or sandpaper for refurbishment to avoid residual sand and cause poor contact. 5. If the power relay contacts are welded, the contacts should be replaced. If the contact capacity is too small, replace the relay with a larger capacity. 6. If the contact pressure is

The power relay functions as an electrical device that turns the controlled output circuit on or off when the input amount reaches a specified value. The  Power Relay China  can be divided into two categories: electrical quantity relays and non-electrical quantity relays. The power relay has the advantages of fast action, stable operation, long service life and small volume. Power relays are widely used in power protection, automation, motion, remote control, measurement and communication devices. 1. The power relay has the insulation performance of the map. It can reach the dielectric constant of 80,000V÷mm in the state of the map. Since there is no oxygen, it will not oxidize during the application process. Thus, the relay is small and stable during the application process. Contact resistance. 2, power relay high electric strength, rated carrying current and conversion current is large, contact contact resistance is small, the obligation is stable, low noise, small inter-distrib
