Input voltage: 4.5 v to 28 v; output voltage: 0.8 v to 20 v. Output current: 3 a (maximum); conversion efficiency: 92% (maximum).

The buck module has 2 heat sink that could enhance heat dissipation. With a wide input voltage range from 6v to 40v, the step-down converter can accurately adjust output voltage and current. When there is a big difference between input and output voltage, please decrease power and current. It is designed with 75v/80a large current dual mos tube. Wiring is convenient with these large current 30a screw terminals. The efficiency can be up to 96%, measured at 20a, converting 24v to 12v.

Perfect for electronic hobby project, wide application, you can use it on radio, car audio, led display, motor, cell phone, etc. Fully sealed, outer enclosure acts as a heat sink, specially made to be waterproof, anti-shock, anti-humidity and dust-proof, more durable. Uses synchronous rectification technology, has high conversion efficiency and stable performance; the input should be at least 3v higher than output. With potentiometer on the bottom, which allows you adjust the accuracy with the mini screw, but ensures you won’t easily change its setting when mounted. With reversed-connection protection, over-current protection, over-heating protection and over-voltage protection, hence is safe to use.

Note: the dc-dc buck converter can work stably at 3a indoor (test condition temperature is 29,, and humidity is 50%). If it s for long time work, it is recommended adding heat sink. Output indicator: the volt transformer board is with a indicator light, which is green and the display is bright, clearly visible and not glare. Parameters: drok buck converter input voltage range is dc 3-40v, adjustable output voltage range is dc 1.23-37v, max output current is 3a, conversion rate can up to 92%. Safe protection: the step down power supply module is designed with reverse connection protection, over current protection, overheat protection, short circuit protection.

High precision potentiometer: the buck circuit adopts imported bi potentiometer, with high resolution, sensitivity, reliability.

Drok dc-dc buck voltage converter input voltage range is dc 10-75v, adjustable output voltage range is dc 0-60v, adjustable output current range is 0-12a, max output power is 720w. Equipped with cooling fan: the power converter comes with a small cooling fan. Constant current & voltage: the step down converter can adjust to constant output voltage, or constant output current by the key. Auto output: the programmable voltage transformer can be set automatic output after power on.

Drok buck converter input voltage range is dc 4.5-24v, adjustable range is 0.8-17v, fixed output are 1.8v.2.5v.3.3v.5v.9v.12v that can be chosen on the back side. Output current is 3a max (please enhance cooling work when it is full load); when real tested input 12v and output is 1.5a, no need to add special system. Output integrated adjustable and fixed voltage, you can get fixed output voltage by soldering the pot on the board. If the fixed output voltage is not what you want, you can adjust by potentiometer. Strong and high quality construction: imported potentiometer and 3a current chip, high current shielded inductors and mlcc solid capacitance with long service life. Integrated enable port defaults the working mode and it will be off when it is at low electric level off, which bring a great convenience for users.

High efficiency and super compact size, high frequency and low ripple, stable working performance, wide range of applications, will be a good component for fixing work.

Input voltage: 4.5v-30v ; output voltage: 0.8v-30v( continuously adjustable ); output current: 0a-12a 100w ( can be up to 200w if enhance heat dissipation ). Tvs tube can effectively prevent surge breakdown voltage, make the work safer and more reliable. Coming with enhanced enhanced aluminum radiator make the work temperature is lower and more stable. 50v/mlcc chip capacitor, combined with high frequency low resistance electrolytic condenser, make the output ripple lower. Short-circuit protection (14a max) combined with over-temperature protection (automatically shut off the output once over temperature), safe and reliable.

Module name: 12a dc step down buck converter.

Four screw holes in the board enable you to mount the module more conveniently and easier. It has the tvs diode to prevent voltage surge from breaking the chip d, hence allowing safer module operation. There is led indicator in the module, making the operating status of this board clear. Super dense and reinforced aluminum radiator allows lower and more stable operating temperature. V-twin for input and v-out for output; installation of four 3 mm screws.

Input voltage: 5-30v dc, output voltage: 0.5-30v dc, max load: 60w/4a peak.35w/3a sustained (whichever is lower, amps or watts). Conversion efficiency: up to 88%, (our test results: 24v- 12v1a: 86.5%.12v- 16v1.5a: 85%.8v- 16v1.5a: 74%). Low input voltage or a large difference between input and output voltage will degrade the current capacity and efficiency (boosting 5v to 12v only works with very low current). The module will cut out if it is unable to source enough input current. Dimensions: 65x32x21mm, fp5139 ic with external mosfet, sepic topology.180khz switching frequency. Maintain stable output voltage and limit the output current over a wide range of input voltages. Great for general voltage conversion, battery charging, powering raw leds, automotive electronics, battery conversions, micro-controllers, and electronic projects.

With voltmeter/ammeter/power meter itself, can be directly used without outside multimeter. Drok buck converter input voltage range is 5-36v, output voltage range is 1.25-32v continuously adjustable, default output 17v, max output current is 5a(please use it within 4.5a). With usb port, can be used to charge for digital products. (note: usb output voltage is the same as the module voltage output, please check before using. Can be a constant current led driver module; also can be a battery charger for solar panels, wind driven generator. Can be buck converter with over current protect function, won’t be burned even if short circuit.
