2900326

2900326 application field and working principle is based on special silicon-controlled transistor core and terminal contact points that form a switching control loop. It is a kind of special switch appliance with relay that has the characteristics of long service life and high baking voltage.

Application Field

2900326 power relays are widely used in communication equipment, audio equipment, industrial automation equipment, home appliances, telecommunication systems, setting up road control systems and energy systems. It plays the role of current, voltage, power and overload protection, making the circuit more reliable and safer.

Working Principle

When the coil voltage of 2900326 power relays is applied, the coil current is instantaneously changed from zero to the rated value. Under the action of electromagnetic field, the armature of the relay is attracted, and the initial contact is connected to close the circuit. At this time, a signal will be given to drive the connected load.

During the process of 2900326 power relays working, the contact points can maintain uninterrupted electrical connection. The concentration of current protection can maintain the safe running of each part of the circuit, thus achieving the goal of protecting equipment and avoiding failure.

When the circuit is opened, the 2900326 power relays can still maintain its act states, that is, the magnetic force of the armature coil will not be lost and the connected electric link will not be disconnected. When the power supply is switched off, the 2900326 power relays will still remain closed.
