Introduction

The G2R-1Z4-AC120 is a power relay specifically designed for applications requiring more than two amps. Its main purpose is to provide controlled, continuously variable electrical power from one or more sources to equipment, components, and/or systems.

Application Fields

The G2R-1Z4-AC120 is capable of many applications, including:

• Automotive electronics
• HVAC/R systems
• Lighting control systems
• Motor speed control
• Power factor correction
• Electrical appliance control

Structure

The G2R-1Z4-AC120 consists of three core elements: an Electric Control Unit (ECU), a Load Unit, and an Electrical Contacts Group.

Electric Control Unit (ECU)

The ECU is the primary control mechanism of the G2R-1Z4-AC120, responsible for controlling and regulating the power signal from the power source. The ECU can be programmed and adjusted to provide tuned and customized electrical power to three-phase systems and other specialized applications.

Load Unit

The Load Unit is responsible for the receiving end of the power circuit, taking electricity from the ECU and converting it into usable power for the system or component that it feeds. The Load Unit is composed of two distinct parts: the current transformer and the core.

Electrical Contacts Group

The Electrical Contacts Group is a set of current-carrying contacts that opens and closes the power continuation. It includes four distinct elements: the contact load, the contact poles, the contact filter, and the contact springs. The contact load, the largest element within the group, is responsible for carrying the main electrical current, while the contact poles and the contact filter provide insulation and aid with protection and control of the load. Lastly, the contact springs are what make the system possible, ensuring that the contacts are closed or open when required to form the power circuit.

Working principle

The working principle of the G2R-1Z4-AC120 is based on its ability to control the power flow through the Load Unit. This is achieved by providing tailored electrical power to the load according to the desired current and voltage levels set through the ECU. The Load Unit steps up the electrical power of the ECU, converting it to usable power, while the Electrical Contacts Group enables the power to be directly connected to the load’s terminals.

Due to the electro magnetic field established by the current transformer, the Load Unit is monitored and regulated in order to provide the correct power levels to the load at all times. Upon the initiation of the power cycle, the ECU takes the electrical power from the power source, converting it to the tailored electric signal required by the Load Unit, and connects it to the load through the Electrical Contacts Group. This process is repeated continuously until the power cycle is complete.

Conclusion

The G2R-1Z4-AC120 is a power relay designed for applications that require more than two amps of power. It incorporates a unique combination of Electric Control Unit, Load Unit and Electrical Contacts Group, which enables it to provide continuously variable electrical power from any type of power source. By regulating and controlling the power flow from the source to the load, the G2R-1Z4-AC120 ensures that the necessary power levels are met reliably and accurately.
