Relays are vital components in electrical and electronic systems, enabling the control of circuits with a low-power signal. One of the most important factors to consider when selecting a relay for your project is its voltage rating. This article delves into the significance of relay voltage ratings, highlighting the role of Meishuo relays in offering reliable and high-performance solutions.
What is a Relay Voltage Rating?
A relay’s voltage rating refers to the maximum voltage that can be applied to the relay’s contacts without causing damage or failure. This rating is essential for ensuring that the relay functions as intended, particularly when switching between different voltages in various circuits. The voltage rating is divided into two main categories: the coil voltage rating and the contact voltage rating.
Coil Voltage Rating: This refers to the voltage required to energize the coil of the relay, causing it to change states (from open to closed or vice versa). The coil voltage determines the relay’s activation conditions.
