Preface
Dianxiaoer has launched a new generation of outdoor power station 1000 Pro 2, which has made major upgrades in many aspects such as charging speed, output power, safety and durability. The three charging methods of mains, solar power and on-board car charger allow users to recharge with peace of mind wherever they go, and the higher AC inverter output power makes it not a problem to use on-board refrigerators, electric kettles, frying pans and other equipment. In addition, it is equipped with a variety of DC output ports to meet the charging needs of laptops and mobile phones. The new upgrade brings a better experience to users' outdoor recreation, outdoor operation and emergency backup and other power consumption scenarios.
When dismantling the outdoor power supply of Dianxiaoer, the charging head network found that the product has a built-in core electronic Hall current sensor CC6910, which has the characteristics of higher accuracy, simpler application and lower loss compared with the resistance sampling scheme, which is very suitable for the application of high-power power supply equipment.
Electric Xiaoer Outdoor Power Station 1000 Pro 2
The 1000 Pro 2 continues the classic black and orange design language, but the design has been upgraded, and the volume is 18% compressed compared with the previous generation, making it more compact and portable. The front of the fuselage is equipped with LCD digital display screen, lighting, 2C1A and multiple DC output ports of cigarette lighter, and two sets of 3+2 combined AC jacks.
In addition, this outdoor power station is not only equipped with a main switch, but also equipped with an independent control switch for each functional module, and also has an indicator light prompt, which makes the on/off status clear at a glance, and the use is more flexible and safe. The LCD digital display screen can display the current input and output power, remaining power and remaining power consumption time. There is also a built-in LED light on the right side, and the configured independent switch can be adjusted in three modes with different clicks, and in case of an emergency, it can be set to continuously flash the SOS rescue light to help get out of trouble in an emergency. The lower two sets of 3+2 national standard AC jacks support up to AC 1500W pure sine wave output, and there is a safety protection door inside the jack to prevent foreign objects from being inserted into a single hole to ensure the safety of electricity.
After a brief understanding of the appearance and function of the product, the charging head network continues to introduce its built-in Xinjin electronic Hall current sensor CC6910.
Xinjin Electronic Hall Current Sensor CC6910
The built-in current sensor of this outdoor power station comes from Xinjin Electronics, model CC6910. It is a high-performance Hall-effect current sensor that supports DC and AC measurements with high accuracy, excellent linearity, and temperature stability for a wide range of industrial, consumer, and communications applications. The chip has 2.5A, 5A, 10A, 20A, 25A, 30A, 40A, 50A and multiple ranges, and the amount is SOP8 package.
The CC6910 is manufactured using an advanced BiCMOS process and supports an operating temperature range of -40~125°C. It contains multiple components such as high-sensitivity Hall sensor, Hall signal preamplifier, common-mode magnetic field suppression circuit, temperature compensation unit, oscillator, dynamic offset elimination circuit, amplifier output, etc. In addition, the integrated differential common-mode suppression circuit of the chip can make the chip not affected by external interference magnetic signals, and the built-in dynamic offset elimination circuit IC sensitivity is not affected by external pressure and IC packaging pressure.
Summary of the charging head network
The charging head network understands that Xinjin Electronics CC6910 has a wide measurement range, has multiple gears to choose from, and has a wide range of applications. At the same time, this chip also has excellent characteristics such as high isolation withstand voltage, low conduction resistance, low loss, strong resistance to mechanical stress, good temperature stability, and excellent anti-interference ability, which can be used to replace the sampling resistor scheme and avoid the additional loss caused by the sampling resistor. It is suitable for a variety of applications that require current sampling, such as motor control, load monitoring, switching power supply, overcurrent protection, photovoltaic power generation, energy storage, and new energy vehicles.
