Power relays, which can handle current higher than 2 Amps, are essential devices to industry, especially for those which require magnitudes of load switching. The ADW1203TW is widely used in such circumstances. This article would analyze the applications and explain the working principle of the product.

Application field:

The ADW1203TW is basically a miniature power contactor-style relay. With its rated current of 3A, it has been used in many industrial applications, such as controlling machine tools and electronics furnace controllers. The ADW1203TW has become one of the most widely applied power relays due to its reliable contact switching capability and its ability to be designed for a variety of applications.

The ADW1203TW is specifically designed for miniaturizing equipment, such as vehicle control applications. Its small size and low power consumption allow it to be effectively integrated into these types of environments without taking up too much board space or energy.

The ADW1203TW is also commonly used in medical and household appliances. Its small size, reliable contact switching capability and ability to be designed for a variety of applications make it an ideal solution for appliance manufacturers. Medical equipment like therapeutic machines also use this device as its high-performance and low-power profile are great for tight spaces in medical environments.

The ADW1203TW is further applied in various industrial and commercial applications that require switching mechanism with high current and voltage ratings. These applications can range from conveyors, pumps, and Inverters to AC and DC Motors.

Working principle:

The ADW1203TW is a 3-pole contactor-style relay, which consists of three coils with an integrated coil shield. When one of the coils is energized, a pair of armature blades close and separate the three contact pins. The 3-pole contactor-style relays are designed to operate in industrial environments where there is a lot of vibration or other effects that could disrupt the operation. To ensure reliability and prevent the contact pins from opening unintentionally, the ADW1203TW features an extra safety pin that is triggered when the relay is de-energized.

The internal construction of the ADW1203TW relay consists of a main coil, a pair of metal blades (armatures), and a safety pin. The coil operates when it is energized and the blades close to separate the three contact pins. The safety pin is mounted on the outside of the relay and is triggered when the relay is enerigzed and breaks contact with the three contact pins to prevent them from opening unintentionally.

The ADW1203TW relay has an average power consumption of 0.8-2W. It also features a temperature range of -20°C to +85°C and can withstand a voltage of 250VAC and 30VDC. The contact pins can handle up to 3A and an instantaneous current of 10A.

Conclusion:

In conclusion, the ADW1203TW is a widely used miniature power contactor-style relay that is designed to operate in industrial environments. It has a rated current of 3A and is often used in applications such as controlling machine tools, electronics furnace controllers, medical equipment and household appliances. The ADW1203TW features an extra safety pin to prevent the contact pins from opening unintentionally and it has an average power consumption of 0.8-2W. It is able to handle voltages of up to 250VAC and 30VDC, and the contact pins can handle up to 3A and an instantaneous current of 10A.
