Description of 💡 DROK - 90068 DC 12v to 5v Converter, DC-DC 10v-35v 24v to 5 Volt Regulator, High-Current Power Supply Module - 20A

DROK buck converter input voltage range is DC 10v-35v ( for protect 12V battery, when the using battery Voltage less than 10V the Item will NOT work ). The voltage regulator module has a high current 20A, output Voltage is DC 5V, can convert 12V / 24V to 5V. Our volt transformer is made of Aluminum, suitable for a variety of adverse working conditions. The power supply module is with overcurrent protection, short circuit protection, overheat protection. The step down converter is commonly used in LED display, toy cars, motors, audio, navigation, Surveillance, air conditioning, electric fans, solar energy, etc.

Amplifier power is orders of magnitude too high

I bought this to power an LED display from a 12 volt battery (solar) system. After only a 2A load, the output has a horrible sawtooth pattern with peaks of 6.2V. I don't have a large enough capacitor bank to test the actual output power of this device, but judging by the pulse width, I daresay saying will not fit.

Pros
  • Lighting and power
Cons
  • I will add later

You get what you pay for.

They're incredibly cheap, small and work well; but the output is very loud. I put a 5 amp load on the 20 amp version and the output had very high peaks around 100kHz and smaller peaks at much higher frequencies. Adding a bunch of capacitors at the output should calm it all down. I just bought and tested this power supply, so I don't have a long experience yet.

Pros
  • Electric
Cons
  • -

The best of the best Converter

DROK emailed me asking for my opinion on this product. I don't normally waste time on reviews in my busy schedule, but I have to say that this particular product is very impressive. I have a hobby and use this converter to power many 5V DC projects, most of which are going from the workbench to the field for portable use. I tested this power supply and can only say that DROK did everything right. Tension stability is the best I've seen and surpasses anything I've built in the last 5 decades…

Pros
  • Ammeter
Cons
  • Not everything fits
