Goupchn 400A Battery Monitor with 2.4 Ultra Clear Display and Wireless APP Control

From the Brand

Years ago, our company had dedicated factories that produced high-quality test lead kits, accessories, oscilloscope probes, and other merchandise. Our experienced team constantly researches market demand and, with years of practical production experience, continues to innovate and provide customers with top-quality products.

How Do We Start?

Firstly, we are experienced in production, and secondly, we have a strict quality control team that routinely checks the items before they are sold, ensuring the superior quality of our merchandise.

Product Description

The KH-F series battery monitor is an upgraded coulomb meter that can measure various physical parameters, such as voltage, current, power, charge and discharge capacity, watt-hour, and time. It also features multiple protection functions, including over-voltage protection, under-voltage protection, over-current protection, over-power protection, over-temperature protection, and time limit protection.

Features

• The newly designed sampler case provides convenient fixation of the sampler while also offering good insulation protection. • The display module has a built-in buzzer, and when the instrument enters protection mode, the remaining alarm sounds and a pop-up reminder appears on the display screen. • The display module uses a 2.4-inch high-definition color LCD screen with optimized interface upgrades and larger, clearer text. The buttons use silicone material, which adds a comfortable tactile feel while maintaining good operational fluency and fast response speed. • The product automatically recognizes and detects the current in both charging and discharging directions. • It is suitable for various batteries, including ternary lithium batteries, lead-acid batteries, and lithium iron phosphate batteries, as long as the battery is within the voltage measurement range. • The shunt and screws are made of pure copper material, with good conductivity, low heat generation, and low power consumption. In standby mode, it does not consume too much battery power. • The communication protocol is open-source and uses 485 communication, allowing development on tools such as serial port assistants. By switching communication addresses, it is possible to control 99 meters separately. • It supports mobile app control. After downloading and installing the app, it can be connected via Bluetooth to view all relevant data and curves, and all functions can be set through the app. • The mobile app has a curve viewing function, which can display real-time and historical curves of voltage and current, and also supports the export of historical data. • The product can be set to overvoltage, undervoltage, overcurrent, over power, external over-temperature protection, etc. When the value exceeds the protection value range, the instrument output status is turned off (requires cooperation with a relay) to prevent damage to electrical equipment. It can also be set to protection recovery time and delay time, suitable for various occasions.

Wireless Mobile Control

The mobile app allows users to view all relevant data and curves, set all functions, and has firmware upgrade capabilities. The mobile app can display real-time and historical curves of voltage and current, and supports the export of historical data.

Upgraded Shunt

The newly designed sampler case is not only convenient for fixing the sampler, but also provides good insulation protection.

Universal for a Variety of Batteries

No matter if it is a lead-acid battery, ternary lithium battery, lithium iron phosphate battery, or any other type of battery, as long as the battery voltage is within the measuring range, all are applicable.
