MY4-AC110/120

The MY4-AC110/120 is a power relay designed to switch a load when the contact energizing voltage exceeds a predefined level. This is achieved by measuring the difference in voltage applied to the two contacts of the relay, and closing the contact when a specific level is met. The MY4-AC110/120 is specifically designed for applications dealing with voltages up to 120V AC. It is also capable of switching currents ranging from 0.3A up to 10A.

Overview

The MY4-AC110/120 is a single-pole double-throw (SPDT) contact relay designed to automatically control voltage and current. It is a control component, which can be used in many different ways. It can be used to bridge wires and circuits, to provide extra safety when switching current, or for automated control purposes. It is designed to meet the requirements of applications needing a precise current cut-off and fast response. The MY4-AC110/120 is made using high-grade components and is tested for durability and performance.

Applications

The MY4-AC110/120 is ideal for a wide variety of applications. It is suited for industrial machinery, automobiles, and many other electrical and electronic equipment. It can be used in applications involving power control (appliances, lighting, pumps, circuits, etc.), voltage regulation (inverters, converters, etc.), and overvoltage protection (surge suppressors, protection relays, etc.).

In industrial applications, the MY4-AC110/120 is often used to control the speed of motors and switches. It can also be used to manage the pressure of pumps, or the temperature of furnaces. The MY4-AC110/120 can be used to control the time of lighting on production lines, or to maintain a constant voltage in closed-loop systems. In commercial applications, it is commonly used to control water heaters, air conditioning systems, and fire systems.

Working Principle

The MY4-AC110/120 is a single-pole double-throw relay. It is designed to switch a load when the voltage applied to its two contacts exceeds a predefined value. When the voltage applied to the two contacts is equal, the contact is open. When the voltage applied to one contact is lower than the other, the contact is closed, allowing current to pass through. The MY4-AC110/120 is designed to switch a load when the contact energizing voltage exceeds a predefined level.

To achieve reliable performance, the MY4-AC110/120 is equipped with a precisely machined and tested mechanism. The contacts are precisely spaced to ensure reliable and consistent operation. The contact gap is adjustable to provide a range of current switching points. The contact gap is adjustable up to a maximum of 0.5 mm. The contact gap determines the maximum current switching point. To achieve the most precise current switching point the contact gap should be adjusted accordingly.

The MY4-AC110/120 is designed with a fail-safe feature. If a contact energizing voltage exceeds predefined levels, both contacts of the relay open, allowing the load to be switched off. This feature prevents damage resulting from excessive voltage or current.

Conclusion

The MY4-AC110/120 is a power relay designed for applications dealing with voltages up to 120V AC. It is capable of switching currents from 0.3A to 10A. The MY4-AC110/120 is a single-pole double-throw contact relay designed to automatically control voltage and current. It is suitable for a wide range of industrial and commercial applications, including motor speed control, voltage regulation, and overvoltage protection. The contacts are designed to switch a load when the contact energizing voltage exceeds a predefined level, and are adjustable to accommodate various current switching points. The MY4-AC110/120 also features a fail-safe feature which prevents damage resulting from excessive voltage or current.
