They have good waterproof and dustproof performance, and can withstand high temperatures, high humidity, and other harsh weather conditions.

The DC Battery Switch is a crucial component used in various applications to control the power supply from a DC battery source. This switch is designed to handle DC loads and effectively disconnect the battery when needed. It is typically used in automotive, marine, and other applications where DC power is used. The switch ensures the safe operation of the equipment by controlling the power flow from the battery. It is designed to handle high current and voltage, and it is usually robust and durable to withstand harsh conditions. It can also protect the battery from over-discharge, thus extending the battery's lifespan. The DC Battery Switch is easy to install and operate and is an essential safety device in any DC power system.

DC Fuse is a type of electrical equipment mainly used to protect electrical devices or circuits in direct current (DC) systems from damage caused by overcurrent. When the current exceeds a set value, the fuse will automatically cut off the circuit to prevent electrical devices or circuits from being damaged by overcurrent. DC fuses are generally used in new energy vehicles, solar photovoltaic systems, power systems, wind power generation systems, and other DC power supply systems. Its main role is to protect electrical devices or circuits in DC power supply systems from overcurrent damage.

A Rail-type Electric Meter, also known as a DIN rail electric meter, is a device used to measure electrical consumption in a convenient, compact form factor. This type of electric meter is designed to be mounted on a DIN rail, a standard type of mounting rail used in industrial control equipment. The major advantage of a Rail-type Electric Meter is its size and ease of installation. Its compact design allows it to be installed in tight spaces or in existing electrical panels without requiring major modifications.

These electric meters can offer a number of features including real-time energy consumption monitoring, power factor analysis, load profile recording, and communication capabilities for remote monitoring and control.

A mini isolated dual power supply is a small, isolated dual power supply device. The isolation feature means that the power supply can isolate the electrical connection between the input and output, which can enhance the safety of the device by preventing reverse current flow or electromagnetic interference. This type of power supply typically has two independent power outputs to meet the power requirements of different devices. Due to its small size, it is easy to carry and install, making it very suitable for situations that require multiple power sources.

Over-Under Voltage Protector, also known as Voltage Protection Device, is a crucial electronic device used to protect electrical appliances from damage caused by voltage fluctuations. Voltage can sometimes exceed or fall below the ideal or safe value due to various reasons such as power outages, power surges, or faulty wiring. These fluctuations can cause serious damage to electrical appliances by overheating, causing a short circuit, or even burning out the internal components. The Over-Under Voltage Protector works by continuously monitoring the voltage supply. If the voltage goes above or below the safe range, the device will automatically disconnect the power supply, thus protecting the electrical appliances from getting damaged.

A mini dual power supply is a small device that can provide two power outputs. It is commonly used in various electronic devices and circuits. It can simultaneously provide power to two devices, or provide power to two parts of one device, making it ideal for situations that require multiple power sources. Mini dual power supplies usually have two independent power outputs, which can adjust the output voltage and current separately to meet the power needs of different devices. Its small size makes it easy to carry and install, and it usually has high energy efficiency, which can reduce energy waste. In addition, mini dual power supplies usually have functions such as short circuit protection and overload protection, which can protect the power supply and devices from damage in abnormal situations.
