Description
  • weight: 485 g

Specifications:

Color: Silver
Material: Metal
Size: Approx. 60 x 52 x 27mm / 2.36 x 2.05 x 1.06''
Input Voltage: DC 6-40V (10V to 40V is suggested)
Output Voltage: DC 1.2-36V
Output Current: 20A(max.), 15A (suggested)
Efficiency: 97% (24V to 12V, 20A)
Output Ripple: ≤50mV
Wiring Method: Terminal
Short Circuit Protection: Self-recovery (cannot short circuit 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 output; suspension, high voltage level is effective
When input and output is common grounded, no-load CV output constant voltage, CC output constant current
Working Tempreture: -10°C-75°C

Features:

With a wide input voltage range from 6V to 40V, the step-down converter can accurately adjust output voltage and current
The efficiency can be up to 96%, measured at 20A, converting 24V to 12V
Designed with 75V/80A large current dual MOS tube
The buck module has 2 heat sink that could enhance heat dissipation
Wiring is convenient with these large current 30A screw terminals
Input and output use high frequency low resistance electrolytic capacitor, low ripple, stable output
Stable and reliable
Fine workmanship and durable

Package included:

1 x 300W 20A adjustable step-down converter module

He probado el step down y reduce el voltaje perfectamente. A diferencia de otros que compré similares estos traen el disipador un poco más fino. Para el embalaje yo recomendaría ponerles una base de plástico acolchado para proteger los componentes SMD que están en la cara inferior. En mi caso han llegado perfectamente pero recomiendo lo anteriormente dicho.

Works great for DIY! don’t touch the circuit or especially not the radiators even when power is off. There is a lot of residual current sitting in it for a couple of hours. Use the one hand rule.

I took some measurements. For input = 24V, output-min = 1.4v and output-max = 23V (Input Current = 12 mA and 31 mA when Output Current = 0 mA.) Input: 24V - 450mA when Output: 10V - 1A. Input: 24V - 68mA when Output: 10V - 83mA. In summary, I am satisfied with the product.

very good, very easy to set up, using as current limiter for Banggood LED COB lights that were getting too hot

Good DC to DC changer. Useful for your DIY projets. Up to 300W just with the quick cooler othervise it can burn-out very quickly. Good design with the srew in conductors sockets. On-off switch is also advantage. Just dont exceed the input voltage it has no overvoltage input protection. The parametric data included which is great.

A good DC-DC converter. I use it to regulate the output power of a LED power supply for my hobby projects. The filter capacitor for the trimmer potentiometer has a dedicated spot on the PCB. This is not common for some of these boards which can be annoying when you want to replace the trimmers to some other potmeters. The solders look nice and clean. Heatsink goes hot when larger power is used, so it is a good idea to use some fan to keep it cool.

Купил по акции. Преобразователь стоит своих денег. Обязательно проверьте хорошо ли затянуты элементы к радиаторам. Заменил потенциометры.

The unit is OK. I tested it for 24V input, 11V output ay 10A current. The output voltage is relatively constant (from 11.5V no load to 11.2V at 10A). The temperatures are: 100 dgr.C for transformer, 100 dgr.C for one heatsink and 80 dgr.C for the other.

Great little power supply. unfortunately out of the 3 I purchased 2 of them had SMT components that were not soldered to the board correctly. the other board had been manually re-worked and the flux reside had not been cleaned off.. The quoted ripple voltage of 50mV is not accurate either, because it only has electrolytic filter caps on the output it has sharp spikes of over 300mV.. soldering some SMT ceramic capacitors across the output capacitors fixed this up and reduced the ripple to a very reasonable 10mV under 100W load. in my photos you can see where I soldered the ceramic caps. In my pictured the red circles are where I installed the ceramic caps. and the green circle is where the component wasnt soldered correctly on the 2 boards.... the glossy look is from a moisture proof laquer I applied to the boards
