Product Description

Features: 1. 4 independent dedicated charge management IC, can effectively support a variety of mobile phones for maximum current charging, charging speed, safe and reliable.2. The charge identification IC is compatible with Apple's full range of Android products. The vast majority of mobile phones can achieve the fastest charging speed.3. Supports 4-channel USB for simultaneous 2A current charging, large current charging, and total output current up to 8A.4. Input adopts MOS tube reverse connection protection, which maximizes conversion efficiency and reduces loss.5. Output with over-voltage protection to see effective protection of mobile phones.6. 8-35V ultra-wide input voltage, 12V 24V car can perfectly support. Module parameters: Input voltage: DC 8-35VInput current: 5.5AOutput voltage: 5.2VOutput current: total maximum 8A, self-adaptive, mobile phone single port charge up to 2A.Dynamic response speed: 300us (load flow change 5)Conversion efficiency: 95 (measured at 12V to 5.2V3.5A, efficiency is related to differential pressure and load size.)Load regulation: 0.2-0.3 (measured by 10 load and 12V input)Ripple & Noise: 120mVP-P (20MHz Bandwidth 12V to 5.2V3A Measured)Switching frequency: 100KHzNo-load current: 18mA (measured by 5V at 12V)Wiring method: IN input OUT input Terminal block DC blockFixed method: M3*1 M2*2Appearance size: 54 (long) * 39 (width) * 21 (high) mm (including USB port) Supporting device :Mobile phones, digital cameras, tablet computers, navigators, tachographs, etc. that require USB powered devices.Can charge 4 mobile phones at the same time, 4 total current 8A.A variety of input and output methods, support terminal input, DC block input, output support 4 * USB output, terminal output 5V. Precautions: (1) Do not use over-voltage and overload, otherwise it will damage the battery and power supply.(2) Modules can only be stepped down and cannot be boosted, and cannot supply power to electrical equipment that is higher than the input voltage.(3) Pay attention to the ventilation and heat dissipation when working with a large amount of current and power for a long time to extend the service life of the power supply.(4) Do not work at full capacity for a long time. Please keep 20 of the margin when working continuously. Pay attention to ventilation and heat dissipation. Package included: 3 x DC8V-35V To 5V 8A Power Step Down Module 4-Port USB Mobile Phone Car Charger
