2.6 Power Supply

In power supply applications, SR-7601 is used to control the amount of current flowing through a circuit. It is used to maintain a steady flow of electricity and to protect against over-voltage and over-current.

3. Working Principle

The working principle of SR-7601 is based on the electromagnetic latching mechanism. When current flows through the input coil, it produces a magnetic field which moves the armature and closes the contact. The signal current then flows through the contacts to the output coil, causing the relay to latch and remain in the closed position. When the input current is turned off, the relay will become unlatched and return to the open position.

4. Conclusion

SR-7601 is a signal relay up to two amps rated. It is designed for signal circuits with varying current, but ranges up to two amps. SR-7601 has a magnetic latching mechanism and is used in many different applications including automotive, factory automation, industrial, medical, aerospace, power supply, and more. The working principle of SR-7601 is based on the electromagnetic latching mechanism. This signal relay is reliable and can be used in many different applications.
