What is a Voltmeter? A voltmeter is a measuring instrument used to measure the DC or AC voltage value in a circuit. In use, in order to ensure that the measured parameters are valuable, the voltmeter needs to have a very high resistance in the internal structure, and the voltmeter should be connected in parallel […]
What is a switching power supply? Switching power supply and linear power supply are the two most important designs of power supply. The power supply is an electrical device whose purpose is to convert the current into the voltage and frequency required by the load device to provide power. Linear power supply: The linear power […]
What is Relay Switch? A relay switch is an electric switching device whose basic principle is to open and close a circuit by receiving an electronic signal from the outside. Relay switches have various sizes, shapes, and designs of different styles, so relay switches have a variety of additional applications in circuits. What are the […]
What is a Smart Relay Switch? A smart relay switch is a device connected to a circuit. The device connects to the user’s smartphone via a wireless protocol, allowing the user to remotely and wirelessly control the opening and closing of the circuit. In practical applications, the use of smart relay switches can provide convenience […]
Nowadays, saving energy is very important. Avoiding the waste of electric energy is something we can do and can do. The use of timer switches allows us to avoid unreasonable loss of electric energy through time management. What is a Timer Switch? A timer switch is an electronic device that turns a circuit on or […]
What is a Power Distribution Box? 18 Ways IP66 Waterproof Distribution Box Electrical distribution boxes are used in commercial and residential buildings and are part of the electrical system, also known as switchboards. It integrates power distribution, protection, and monitoring capabilities, and is responsible for distributing power to entire commercial or residential buildings. To put it […]
What is the Meaning of AFDD? AFDD full form in electrical is Arc Fault Detection Devices, which is installed in consumer units to prevent arc faults. This device continuously observes changes in the circuit, and once a dangerous arc is detected, the AFDD quickly trips to disconnect the circuit, preventing further overheating. What is an […]
Meaning of RCBO RCBO combines the functions of MCB and RCD, and is an abbreviated expression of “residual current circuit breaker with overload protection”. Overcurrent refers to excessive current caused by too many load devices in the circuit or short circuit in the circuit. Residual current, also commonly known as earth leakage, refers to an open […]
How to Use a Smart Circuit Breaker The smart circuit breaker can realize the switch gate through remote operation, and use the APP to monitor and collect the conditions of the circuit and load equipment in real-time through the Internet. The following is the video of Tongou intelligent RCBO circuit breaker TOSMR1, which describes the […]
How do circuit breakers work? Before understanding how a circuit breaker works, we can briefly understand the circuit. A circuit refers to a loop in which the current in the power supply is output to the load device through a conductive substance and then returned to the power supply. If there is no load device […]
