DC 530V to 1.2530V DC Buck Boost Converter Automatic Voltage Regulator Module 10A Efficiency

Nonisolated synchronous rectification automatic stepup/stepdown DC power module designed for flexible voltage and current control in compact systems. Key benefits Wide input and output range: accepts DC 5 to 30 V and provides a continuous adjustable output from 1.25 to 30 V for broad compatibility with batteries, solar panels, and vehicle electrical systems. efficiency and low standby draw: Typical conversion efficiency 91% and up to 93% at conditions, with low quiescent current around 4 mA. Builtin protections: over current protection, short circuit current limiting, and over temperature behavior that reduces output to protect the module. Thermal management: two dedicated heat sinks and recommended cooling practices allow sustained performance; reduce load or add cooling if module temperature exceeds 65 C. Compact and easy to wire: terminal block input and output labeled IN and OUT; module weight about 70 g. Key specifications Type: nonisolated synchronous rectification automatic stepup/stepdown module Input voltage: DC 5 to 30 V Input current: typical 8 A, maximum 10 A; recommend keeping input below 6 A for continuous longterm operation Quiescent current: about 4 mA (may vary with working voltage) Output voltage: adjustable 1.25 to 30 V continuously Output current: maximum 10 A; for longterm use keep within 5 A with adequate cooling; reduce rated load at higher output voltages Constant current range: 0.2 to 10 A Operating temperature: 40 to 85 C Switching frequency: 150 kHz Conversion efficiency: typical 91%, up to 93% Protections: over current, short circuit with current limiting, over temperature automatic reduction Reverse input: none built in; add a series diode at input if reverse polarity protection is required Output backflow: prevented, no diode needed for charging Wiring: terminal block, IN is input, OUT is output Weight: approximately 70 g How to set voltage and current Set output voltage first: adjust the CV potentiometer to the desired voltage based on the load or battery specifications. Limit current setting: rotate the current potentiometer fully counterclockwise (about 30 turns) to reach minimum output current, then connect the load or LED and adjust clockwise to the required current. For battery charging: connect the module to the battery after it is discharged to the required level, then set the charging current. Charging current will decrease naturally as battery voltage rises. Do not use a short circuit to adjust current. Practical notes and safe operation For continuous, longterm operation keep input current below 6 A and output current within 5 A unless extra cooling is provided. If output voltage is or module temperature exceeds 65 C, improve heat dissipation or reduce the load to prevent thermal limiting. Add a series diode at the input if you need reverse polarity protection; no additional diode is required on the output when charging because output backflow protection is present. Avoid prolonged operation at maximum ratings to preserve component life. Applications and use cases Battery charging and management: adjustable constantvoltage and constantcurrent control makes it suitable for charging lead acid, lithium, and other battery packs when set to appropriate profiles. Automotive and vehicle accessories: convert 12 V or 24 V vehicle sources to stable voltages for sensors, lights, and electronics. DIY power supplies and test benches: small, efficient adjustable regulator for prototyping, LED drivers, and bench power applications. Solar and offgrid systems: stepup or stepdown capability works with variable panel or battery voltages to supply regulated loads.
