The key performance parameter of the relay protection device is the rated working voltage. When applying relay HKE, the working voltage of its power supply circuit (that is, the power supply circuit to which the relay HKE coil belongs) should be considered first, and its rated working voltage should be equivalent to the working voltage of its power supply circuit. Generally, the working voltage in the power supply circuit is 0.86 times the rated working voltage of the relay HKE. Note that the voltage of the product workpiece in the power supply circuit must not exceed the rated working voltage of the relay HKE, otherwise the coil of the relay HKE is very easy to burn.
In addition, some integrated circuit chips, such as the NE555 circuit, can immediately drive the relay HKE to work; but some, such as the CMOS power supply circuit, require a first-stage transistor operational amplifier to drive the relay HKE, so it must be considered that the output current of the transistor must exceed The rated current of relay HKE during operation.
