DC-DC Buck Boost Power Supply Module 9A 300W Adjustable Voltage 5-40V to 1.2-35V

This is a DC-DC Step Up Down Power Supply Module designed for electrical projects. It features a 9A 300W Buck Boost Converter XL4016, an adjustable voltage regulator that can convert input voltage from 5-40V to output voltage of 1.2-35V. Made of PVC material, this module does not have a display and requires no assembly.

A new and high-quality DC-DC boost converter with an input range of 10-32V and an output range of 12-35V, capable of providing up to 150W of power. This module features an adjustable static power DC boost voltage regulator with an input current of up to 10A and an output current of 6A. The output voltage is adjustable between 12-35V. The output power can reach up to 150W with enhanced cooling. The conversion efficiency is rated at 94% under specific conditions (Input: 19V 2.5A, Output: 16V).The ripple effect is limited to a maximum of 2%. The operational temperature range is industrial (from 40°C to +85°C) and environmental. If the temperature exceeds 40 degrees, it is recommended to either reduce power usage or improve cooling. The full-load temperature is 45 degrees. The typical no-load current is 25mA. Voltage regulation and load regulation are both at 0.5%. The dynamic response speed is 200uS with a 5% margin. There is no short circuit protection, so please install a fuse or protection circuit at the input parts.To prevent reverse polarity, either use a reverse protection or connect a bond at the input. The dimensions are 65 * 23 * 56.3 mm. This device is suitable for various applications such as adjustable vehicle power supply. By connecting a 12V input, the output voltage can be adjusted between 14-35V. Please note that the output voltage should not be lower than the input voltage. It can also be used as a boost charger to charge batteries with a higher voltage than the input, for instance, a 24V battery.To ensure the proper functioning of your electronic devices, make sure to adjust the voltage to the required level and ensure that the current does not surpass the rated limit. When working on a project at the system level, if your system board requires a power supply of around 24 volts while the input is between 10 to 18 volts, and the power demand is high, using a regular DC-DC module might not suffice. In such cases, opting for this specific module would be the most suitable choice as it allows for direct usage without the need for debugging, enabling easy attainment of efficient high-power output.Characteristics of the module: Regulated step-down power supply with constant current and constant voltage (CC CV) for charging purposes. Input voltage range: 7-32V DC. Output voltage options: (1) Continuously adjustable from 0.8-28V DC. (2) Fixed output: Selectable between 0.8V and 28V. Maximum output current: 8A (install a cooling fan if the power tube temperature exceeds 65 degrees). Adjustable constant current range: 0.2-8A.Adjust the lamp current: The lamp current is set to 0.1 times the constant current value, for example, if the constant current value is 3A, the lamp current is set to 0.1 * 3A = 0.3A. The minimum pressure is 1V. The output power is approximately 300W. The conversion efficiency is up to about 95%. The operating frequency is 300KHZ. The output ripple is within a 20M bandwidth. For an input of 24V and an output of 12V at 5A, the ripple is around 50mV (excluding noise).Yes, the device has protection against short circuits by maintaining a constant current. There is no protection against reverse polarity for the input. Backflow prevention for the output is also not available. The device is wired using terminals. The no-load current is typically 20mA (switching from 24V to 12V). Load regulation is ± 1% consistently, and voltage regulation is also ± 1%. The dynamic response speed is 5% in 200 microseconds.Adjust the potentiometer by turning it clockwise to increase and counterclockwise to decrease. The potentiometer near the input voltage is used to adjust the voltage, while the one near the output voltage is used to regulate the current. Operating temperature ranges from -40°C to +85°C for industrial use (consider the actual temperature of the power tube, which is strengthened at high temperatures).The dual color indicator shows red when charging and green when fully charged (green when no load). The approximate size is 65 x 47 x 22mm (L x W x H). During testing, the constant current value changes by less than 5% as the module temperature increases from 25 to 60 degrees (5A constant current value). Output short circuit protection is available with constant current (set at the constant current value).The protection against reverse connection is disabled. There is no prevention of reverse flow. The wiring method is using an Amphenol connector.Key characteristics4. By using four high frequency capacitors, the output ripple can be reduced, and work stability can be improved. 5. The double heat sink design includes independent heat sinks for MOS Schottky diodes, ensuring good heat dissipation without interference. 6. Utilizing large Sendust Core and double pure copper wiring enhances work efficiency and reduces heat generation. 7. Equipped with a 3296 multiturn potentiometer for high-precision voltage and current regulation, ensuring good stability. 8. The double color lamp provides clear indication of the working status.Adjustable voltage and current have a positive impact.To charge the battery: 1. Confirm the required battery float voltage, charging current, and module input voltage. 2. Set the output voltage to around 5V by adjusting the constant voltage potentiometer. 3. Measure the output short-circuit current using a multimeter in the 10A current scale, and adjust the current potentiometer to match the expected charging current value.Set the constant voltage potentiometer to match the output voltage with the float voltage. Connect to the battery and attempt to charge. (Steps 1, 2, 3, 4 involve connecting the power module input and output without connecting the battery.) LED constant current driver: Confirm the operating current and maximum operating voltage of the LED you wish to drive. Tune the constant voltage potentiometer to set the output voltage to around 5V.Step 3: Utilize the multimeter set to 10A current scale to determine the short-circuit current of the output, and regulate the current potentiometer to ensure that the output current matches the anticipated LED operating current. Step 4: Fine-tune the constant voltage potentiometer to achieve the maximum LED operating voltage at the output. Step 5: Connect the LED and conduct a test. (Steps 1, 2, 3, and 4 involve connecting the power module input; do not connect the LED during the no-load output phase.)
