## Description

DROK DCDC Power Supply Stabilizer ModuleTechnical Specification: Input Voltage: DC 9V~36V (12V) Output Voltage: DC 12V Output Current: 5A Output Power: 60W Conversion Efficiency: >90% No Load Voltage Range: Set voltage ±3% Load Regulation: ±3% Quiescent Power Dissipation: <10mA Operating Temperature: -25~65℃ Storage Temprature: -40~80℃ Operating Humidity: 10%~90% Waterproofing Grade: IP67 Over-current Protection: Yes Over-temperature Protection: Yes Short-circuit Protection: No Dimension: 2.24*1.54*0.87 inch Installation Ear Diameter: 0.16 inchNote: 1. Connect the wiring in strict according with the wiring instruction. 2. Use short and thick input & output wire to ensure output enough voltage and power. 3. If there are multiple output wire, do not combine the load. 4. Leave a margin for the power supply to ensure it can long-term stably working.Package Included: 1x DC-DC Stabilizer

Review: Works great with MaxxFan for voltage regulation. - Easy install and quick-fix for MaxxFan voltage errors. Fits inside MaxxFan housing.
Review: Works to protect circuit boards from over-voltage on Power Pole pumps - Installed on boat to regulate power for 2 Power Poles. The circuit boards on the power pole pump motors don’t like voltage levels higher than 13VDC. Just in case they forget to turn the battery switches off before charging. The power pole pump draws 16.4 amps when retracting, and 8.8 amps when deploying. If you are using a single pump to run two poles, you will need a buck converter that can handle 30 amps. The single pump draws 29.5 amps when retracting 2 poles at once.

## Questions & Answers

**Q: If  it fails, does it pass the input voltage straight through or does it block it?**
A: Blocks it and doesn't work

**Q: Vent fan connect to led interior light. led burns out. can this stabilize interior led power save from burn out??**
A: Only one word, excellent !!!!

**Q: Several people have asked if the grounds on this module can be tied together. i asked drok, an they said yes, because the module is non-isolated. ok?**
A: Black wires are already tied together inside module.  One black wire (ground/ return) goes to input, second black wire goes to output/ load.  Have a blessed day!

**Q: Can the 2 negatives share a common ground?**
A: This goes in the line.  You will have a positive and negative going to your load.  You  cut the wires and hook the positive and negative from your power sorce to ine in-side and the positive and negative coming out go to the load.  Simple.

### ⭐ Spectacular failure
*by J***. on February 19, 2025*

I used this for a step-down voltage 5v output on a portable ham radio setup for POTA since November. Everything else required 12v, the tuner required 5v so I added this in line for its power. Seemed to work well. Yesterday the device failed spectacularly. Sudden "pop" noise, smoke, and even flame for a couple of seconds where the case had split. I had to evacuate the car until the smoke had dissipated. Glad I was there when it happened. Definitely done with these things, I will replace those I'm running at home as well. I can't trust them.
