Power Relays are tiny devices that can control an electrical circuit remotely. Specifically, ACC343UMM60 is a type of power relay with an operating voltage of up to 60 Volts DC. It typically has a tolerance of up to ±2% and is capable of switching up to 2 Amps of power with a contact resistance of ≤50 mΩ.

Application Field

Due to its superior performance, ACC343UMM60 is widely used in industries ranging from automotive and motorsport to telecommunications and security systems. In automobiles, it can be used to switch loads, ranging from fuel pumps to solenoids and electrical fans. It is also suited for individual motor control in plant and manufacturing automation, speed control of dc motors in robotics, and for broadcast and surveillance systems. Moreover, it can be used for general purpose switching in a wide range of commercial and industrial environments.

Working Principle

In general, a power relay consists of two terminals connected to a coil and a set of contacts, which open and close a circuit when the relay is activated. The coil normally consists of a strip of fine wire wrapped around the ferrite core. When an appropriate voltage is applied to the terminals, a magnetic field is produced in the core, which, in turn, operates the contact set according to the number of poles in the relay and the number of contact sets. The operating voltage, normally between 5V and 60V DC, can be applied to the terminals via external power source or by means of a control signal. When the voltage is applied, the coil will pull on the armature and close the contacts, thus establishing a connection. When the voltage is removed, the contacts will disconnect the circuit.

The ACC343UMM60 is a single-pole, double-throw (SPDT) power relay which has two sets of contacts that can be switched on and off. It is also equipped with a reverse blocking diode, which prevents backflow current from damaging the relay. Additionally, it also has a high surge current rating, making it capable of switching heavier loads and protect against short-circuiting.

Conclusion

ACC343UMM60 is an efficient and versatile power relay with an operating voltage of up to 60 volts DC and up to 2 Amps of power handling capacity. It is used in a variety of applications ranging from automotive and motorsport to telecommunications and security systems. When equipped with a reverse blocking diode, it can switch heavier loads and protect against short-circuiting. Furthermore, its contact resistance of ≤50 mΩ makes it suitable for switching sensitive circuits and for precision motor control.
