Description

Quantity : 1 High-concerned chemical : none Package : SOP is_d : Yes Supply Voltage : 12-75V Application : 1000W Boost Module Type : Module Brand Name : DIY NOW Origin : Mainland China Condition : New Operating Temperature : -40 to +85℃

Features: 1. Input voltage 10.5-75V, output voltage 12-85V, adapt to a variety of power supply and application requirements 2. Input 36V or more power up to 1000W, to meet the needs of high-power equipment use 3. support constant voltage and constant current output, adjustable voltage and current, to ensure stable and reliable power supply 4. Input current limit 5-40A adjustable, to provide flexible current control, to protect the circuit safety. 5. 4 high power tubes and two ferrosilicon aluminum pure copper coils, to ensure high efficiency and long life

Parameter: Module nature: non-isolated boost module (BOOST) Input voltage: DC10.5-75V Input current: 40A (MAX) (input current formula: output power / input voltage * 1.05 = input current) Input current limit: 5-40A adjustable Output voltage: 12-85V (±3V) adjustable (output voltage can only be higher than input voltage) Static operating current: 15mA (12V to 20V, the higher the output voltage, the static current will increase) Output current: 20A MAX Output constant current range: 0.5-20A (±0.5A) Input anti-reverse: Yes (power MOS anti-reverse) Low battery protection: Yes (10-70V adjustable) Temperature control fan: Yes (over 50 ℃ to open the fan) Operating temperature: -40 ~ +85 degrees (ambient temperature is too high, please strengthen the heat dissipation) Operating frequency: 100KHz Conversion efficiency: 92%-97% (efficiency and input and output voltage, current, pressure difference. (The efficiency is related to the input and output voltage, current and pressure difference.) Input overcurrent protection: Yes (5-40A current limit, will reduce the output voltage or current to reduce the output power) Short-circuit protection: no (prohibit short-circuit output) Input reverse protection: Yes (power MOS tube anti-reverse, can be a long time reverse) Wiring: terminal (please use high-current pure copper wire)

Output power description: Output power: = input voltage * 40A, such as: input voltage 12V, 12V * 40A = 480W, the maximum power of 12V input is 480W Such as: input 24V * 40A = 960W, i.e.: input 24V when the maximum power is 960W Such as: input 36V, 36V * 40A The power is 1440W, more than the power of the power supply, the input current can not exceed 28A. Input 28V or more, output 50V or more modules to reach 1000W

Package include: 1000W boost module * 1 label:yes
