1200W 20A DC Converter Boost Step Up Power Supply Module Input 10-60V Output 12-83V
Specifications:; Module name: 1200W boost constant current moduleModule properties: non isolated boost module (BOOST) Input voltage: 10-60VInput current: 20AQuiescent operating current: 15mAOutput voltage: 12-83V continuous adjustableOutput current: MAX 12A over 20A, please strengthen the; cooling (with input and output differential pressure, the greater; the pressure difference between the output current is small)Constant current range: 0.3 -20AOutput power: = input voltage; x 10AWorking temperature: -40~+85 degrees; Working frequency: 150KHzConversion efficiency: & le; 95% (efficiency and input, output voltage,; current, pressure difference)Installation: 4pcs 3mm columnConnection mode: welding output (please use big current and pure copper wire) Module size: 130mmx52mmx46mm (LxWxH); Feature:; 1. Over current protection: there is a certain range of error in the input over 30A,; automatically reducing the output voltage. 2. Short circuit protection: there is (input 40A fuse) double short circuit protection,; use more secure.; When using the boost power supply should pay attention to the following points:; 1. Input power supply voltage must be above 10V. 2. When the power supply is for the input power supply, the input power and; the output voltage of the input power supply are the first to be unloaded. Then pick; up the load. (must ensure that the switching power supply has been working). 3. When the constant current mode is to set the voltage, the constant voltage; must be higher than the input voltage. Do not use the way of short circuit output current,; the circuit structure of the boost module can not be adjusted in short circuit way. 4.; If the input voltage fluctuation range is lower than the set output voltage, then the output voltage is constant, it is to ensure that input is lower than the output voltage.; Package included:; 1 x 1200W boost constant current module
3pcs XL4015 5A High Power 75W DC-DC Adjustable Step Down Module LED Voltmeter Power Supply Module
Description: KEY_TAB This product is a 180 KHz fixed frequency PWM buck (step-down) DC/DC module, capable of driving a 5A load with high efficiency, low ripple and excellent line and load regulation. The module with a voltage meter to display the input voltage and output voltage, and the voltage can be corrected through the button to improve the accuracy of the voltmeter. KEY_TAB Features: KEY_TAB 1. LED power indicator. 2. Button to switch measurement of the input or output voltage, and LED indicates the current measurement of the input or output voltage; The nixie tube can be turned off by another button. Mentioned states are able to be memorized, is not lost even if the power is disconnected. (On-board marked "IN" LED is turned on, the nixie tube display input voltage value, "OUT" LED bright display is the output voltage value). 3. Special launch, the voltmeter calibration function, will never exist voltmeter inaccurate! Voltmeter calibration method: (1) Output voltage calibration steps Step 1, adjust the right button so that "OUT" LED lighted, the voltmeter shows the value of output voltage; Press the right button for more than 2 seconds, release, voltmeter and "OUT" LED flashes in synchronization so that you enter the output voltage calibration mode. Step 2, press the right button (normal speed), the voltage value is adding up a unit; Press the left button, minus a unit; Due to a is less than 0.1V, the minimum voltage display to 0.1V, so you need to continuously press 1-5 times to see the voltmeter change 0.1V, how many times voltmeter change 0.1V by pressing the key, depending on the current display voltage, the higher the voltage, the fewer the number of press. Step 3, press the right button for more than 2 seconds, release, to exit the output voltage calibration mode. All parameters set to automatically power down to save. (2) Input voltage calibration steps Step 1, adjust the right button so that "IN" LED lighted, the voltmeter shows the value of input voltage; press the right button for more than 2 seconds, release, voltmeter and "IN" LED flashes in synchronization so that you enter the input voltage calibration mode. Steps 2 and 3, consistent with the output voltage calibration method. KEY_TAB Specifications: KEY_TAB 1. Input voltage range: 4~38VDC(Note: input voltage not exceeding 38V) 2.
