self-test 话题标签 to using specific equipment or methods to detect whether there is leakage in the circuit. Leakage refers to the occurrence of abnormal current in a circuit, which may lead to safety issues such as circuit failure, electric shock hazard, and even fire. Leakage self-test can help users promptly discover and solve leakage problems in circuits, ensuring electrical equipment and personal safety.

A common leakage self-test method is to use a leakage current device (RCD), also known as a leakage circuit breaker. The leakage protector can monitor the current difference in the circuit. Once leakage is detected, it will quickly cut off the circuit to prevent the current from causing harm to the human body or other paths.

In addition, you can also use professional leakage detection equipment to perform leakage self-test. These instruments can measure the leakage current in the circuit and provide corresponding alarms or instructions to help users determine whether there is a leakage problem in the circuit.

When performing leakage self-test, you need to pay attention to the following points:

Make sure to use a suitable leakage protector or leakage detection instrument and operate it correctly according to the instructions.
Before performing self-test, cut off the power supply to ensure safety.
Check whether the wiring in the circuit is firm to avoid leakage problems caused by poor contact.
Perform leakage self-checks regularly, especially for electrical appliances or circuits that have not been used for a long time. Check whether there are leakage problems regularly.
Please note that the above information is for reference only, and the specific leakage self-test method and equipment selection should be based on the actual situation and relevant regulations.

-in Boost Technology Solution

1. Provide high water pressure: The built-in booster water pump can provide higher water pressure, making the hot water flow out faster and more powerfully. This means you can enjoy a more comfortable shower experience while filling up your tub or sink more quickly.

2. Improve hot water supply capacity: A booster water pump can increase the water supply capacity of the water heater. It can provide greater water flow, ensuring that each faucet can get enough hot water when multiple faucets are used at the same time. This is useful for large households or where multiple hot water appliances need to be used simultaneously.

3. Solve the low water pressure problem: For users in low water pressure areas, the built-in booster water pump can solve the low water pressure problem. It can increase the pressure of the water flow, so that the water heater can provide sufficient water pressure even in a low water pressure environment, ensuring the stability and comfort of hot water supply.

4. Flexible installation: Instantaneous electric water heaters with built-in booster water pumps can be installed in various locations more flexibly and are not restricted by low water pressure environments. This means you have more freedom in choosing where to install your water heater without having to worry about insufficient water pressure.

In short, the built-in booster water pump of the instantaneous electric water heater can provide high water pressure, improve the hot water supply capacity, solve the problem of low water pressure, and has the advantage of flexible installation. This allows users to enjoy a more comfortable and convenient hot water usage experience.

Choig PCB solution development : Double Relay Control

Dual relay control technology can realize automatic switching and protection of the circuit and has the following functions:

1. Realize automatic switching of circuits: Dual relay control technology can realize automatic switching of circuits by controlling the switching status of two relays. When one relay fails, the other relay can automatically take over to ensure the normal operation of the circuit.

2. Realize circuit protection: Dual relay control technology can monitor the voltage, current and other parameters of the circuit. When an abnormality occurs in the circuit, it can cut off the circuit in time to protect the safety of electrical appliances and equipment.

3. Improve the reliability of the circuit: Dual relay control technology can improve the reliability of the circuit and reduce downtime and losses caused by electrical faults by realizing automatic switching and protection of the circuit.

In short, dual relay control technology plays an important role in circuit control and protection and can improve the reliability and safety of the circuit.
