Power relays are electromechanical devices designed to switch high current circuits with the use of an electrically activated coil. The 2903349 is a type of power relay, capable of switching over two amps. The applications and working principle of this popular power relay are discussed in this article.
Applications
The 2903349 power relay is widely used as a master control in a variety of devices, such as AC motors, large heating and cooling units, and programmable logic controllers. It is well suited for controlling large current loads, and is also capable of operating in a temperature range between -40°C and 125°C.
The 2903349 is often used in safety interlocks, emergency stop buttons, and emergency power supply systems. It is also well suited for automotive applications, such as fuel-pump control, start-stop systems, and diagnostic data systems.
The small size and low cost of the 2903349 has made it popular for use in consumer electronics, including home appliances, home entertainment systems, and medical equipment. Its ability to switch both AC and DC power makes it ideal for a wide range of applications.
Specifications
The 2903349 power relay is a single-pole, double-throw switch. It can be used to switch both AC and DC currents, and is rated for a maximum switching current of 2 amps. It has a contact resistance of less than 50mΩ, a dielectric strength of 750VAC, and an insulation resistance of 1,000MΩ at 500V.
The operating temperature range of the 2903349 is -40°C to 125°C, and it has a maximum contact bounce of 10ms. The maximum switching power of the relay is 160VA. The coil voltage is 5VDC.
Construction
The 2903349 power relay is constructed from a metal alloy housing with a plastic cover. The contacts are made of silver-alloy, and the coil is wound with thin copper wire. The relay has a 12-pin miniature connector, and the total package dimensions are 20 x 13 x 18 millimeters.
Working Principle
The 2903349 power relay works by using an electro-magnetic field created by a circuit with an electrically activated coil. When power is applied to the coil, it creates a magnetic field that moves the armature of the relay, connecting one circuit to another. The contacts and coil of the relay are designed to minimize contact resistance.
The principle behind the operation of the 2903349 is not dissimilar to that of a traditional relay: an electrically activated coil attracts the armature, thereby allowing current to flow. The difference between this type of relay is that it is capable of much higher current switching.
Advantages
The 2903349 is a very reliable and flexible power relay, capable of switching both AC and DC currents. It is a low-cost, low-maintenance device, and its small package size makes it suitable for a variety of applications. It is also rated for high-volatility operation, making it well suited for use in safety-critical situations.
Conclusion
The 2903349 power relay is a powerful and reliable device, capable of switching both AC and DC currents. It is used in a wide variety of applications, including safety interlocks, start-stop systems, and AC motors. Its small package size and low cost make it ideal for consumer electronics. It is a versatile and reliable power relay.
