Automatic Transfer Switch’s Function
ATS arrangements Facilities can choose from many ATS arrangements, which include the following: · Utility-utility. The ATS switches between two utility power sources that provide redundancy in the power system and enable quick restoration of service if the primary source goes down. · Generator-ge...Read more -
Introduction to Lightning arresters
Lightning Arrester: An Essential Electrical Protection Device A lightning arrester, also known as a surge arrester, is a critical protective component in electrical power systems and electronic circuits. Its core function is to divert abnormal high-voltage surges—such as those caused by lightning...Read more -
What is an automatic transfer switch?
An automatic transfer switch (ATS) is a device that automatically transfers a power supply from its primary source to a backup source when it senses a failure or outage in the primary source. Following the failure, the ATS automatically invokes the backup source to minimize power supply disruptio...Read more -
Isolating switch’s function
An isolating switch’s primary function is to provide electrical isolation for safety during maintenance, repairs, or emergencies by physically disconnecting a circuit from its power source, creating a visible and certain break in the circuit. It ensures the circuit is de-energized, preven...Read more -
What Is An MC4 Connector?
MC4 connectors are single-contact electrical connectors. They are commonly used for connecting solar panels. MC4 stands for “Multi-Contact, 4 millimetre”. It is a standard in the renewable energy industry. An MC4 connector enables the easy construction of strings of panels. In today’s solar marke...Read more -
Voltage protector function
A voltage protector safeguards electrical equipment by monitoring incoming voltage and automatically disconnecting power when the voltage goes outside a safe, preset range (too high or too low). After the voltage stabilizes and returns to normal levels, the device automatically re-establishes the...Read more -
Application And Type of Digital Timer Switch
Types of Digital Timer Switches Daily Timer Switches As the name suggests, daily timer switches allow you to set on and off times that repeat every day. These are great for applications where you want your devices to turn on and off at the same time each day, such as lighting or heating systems. ...Read more -
How distribution boxes work
A distribution box works by receiving a single electrical power input and splitting it into multiple, independent branch circuits that power different parts of a building. Inside,circuit breakers or fuses act as safety devices, monitoring each circuit’s power flow and automatically “...Read more -
What is a Digital Time Switch?
In our modern, fast-paced lives, we’re always looking for ways to simplify our routines and save time and energy. Have you ever wished you could automatically turn your lights on and off at specific times, or have your coffee maker start brewing before you even get out of bed? That’s where digita...Read more -
The Functions And Roles of Relays
A relay is an electronic component that uses electromagnetic principles or other physical effects to achieve the “automatic on/off” of circuits. Its core function is to control the on-off of large current/high voltage circuits with small current/signals, while also achieving electrica...Read more -
