300 W 20 A DC buck module, constant current, adjustable step-down converter voltage
output current: 20 A (max.), 15A (recommended)
output voltage : 1.2 V to 36 V DC.
Efficiency: 95% (24V to 12V, 20A)
With a wide input voltage range from 6 V to 40 V (10 V to 40 V is recommended), the step-down converter set the output voltage and current precisely.
Output ripple: less than equal to 50 mV.
Wiring Method: Terminal.
Short-circuit protection: self-recovery (cannot be short-circuited for a long time).
VO +: output positive
VO-: output negative
+ IN: input positive
-IN: input: negative.
CV: Output voltage adjustment.
CC: Output current adjustment
EN: Enable, Low Voltage Level Shut Off Out; Suspension, High Voltage Level is effective
If input and output are grounded together, no-load CV output constant voltage, CC output constant current.
Operating temperature: -10 ° C to 75 ° C.
Designed with 75 V / 80 A large current dual MOS tube.
The buck module has 2 heat sinks that can improve heat dissipation.
The wiring is easy with these 30 A screw terminals.
Input and output use high frequency low resistance, electrolytic capacitor, low ripple, stable output power.
Stable and reliable
Fine workmanship and durable.
Widely used in industrial automation, scientific research equipment, led lighting, air purification, civil equipment, solar panel voltage regulator, battery charging, wind turbine and so on.
Note: Due to the light and different screen settings, the color in the picture may differ slightly from the actual product.
The dimensions can vary by ± 1-3 cm.
Scope of delivery: 2 x high-power buck converter step-down module.

The BGTXINGI 2Pcs 20A 300W High-Power Buck Converter is an outstanding product that delivers exactly as promised. I’ve been using these converters for a variety of projects, and they have performed flawlessly every time. The adjustable constant voltage and constant current features make it incredibly versatile, and it’s easy to fine-tune the settings for different applications.The build quality is solid, with a robust design that can handle high power loads without overheating. I appreciate the clear labeling on the board, which makes installation straightforward even for someone who isn't a professional electrician. The efficiency is impressive, and I’ve noticed minimal energy loss during operation.I’m particularly happy with how stable and reliable the output is, which is crucial for sensitive electronics.

These are not as described. They DO NOT step up as is suggested in the description.

Having bought several models of these, som good some very bad, I cannot say which are the bad. Advice, use antistatic matting. Set this up on a work bench. Current limit & voltage. When they work they are excellent. I'm using these as battery chargers, stable power supplies amongst other uses. I have added fans to keep them cool, 50 * 50 12 volt, also using voltage & current monitor, (Digital Ammeter Voltmeter 2PCS DC 100V 50A LED Volt Meter Voltage Current Meter) fan mounted directly onto of cooling fins.Presently testing with a very "Noisy elect" switch mode PSU, so far so good. No filters added.14 V @ 8 A. Just cranked the load up to 10A. cannot push the load over 10.5A, seems there is a cooling problem on the base of the board, Just confirmed this.Next test will be dual output into same load.Watch this space. So far very happy.FAILURES: Which models dont know1. Could not adjust current.2. Could not adjust voltage.3. Failed, no output.Take care with bridge rectifiers, some fail & output is 70V with high ripple, 4 of these same problem (Even with very good heat sink)
