With a remarkable efficiency of over 95% and built-in safety features, this waterproof converter is ideal for a variety of applications, including golf carts and LED lighting. Designed for extreme conditions, it operates reliably in temperatures ranging from -40°C to 80°C, backed by a one-year replacement guarantee. ## Description Product description YOU NEED TO KNOW Please follow the wiring instruction and connect them strictly： 1.The load connected to the output end of the power regulator should not be more than max listed load power； 2.If there are multiple output wire, do not combine the load. 3.Leave a margin for the power supply to ensure long-term stably working. How to Choose the Correct Current for Loads? For example, if the max current of your load device is 10A, then choose 10A/0.8=12.5A at least for resistive loads according to international standard. If the load device is motor or compressor, then you may choose 10A/0.5=20A according to real testing result since the motor and compressor starting current may be 2-3 times than nominal current. Specification IP68 Waterproof Module DC voltage converter with Strict epoxy potting process is waterproof, anti-dust, anti-shock and adapt to a variety of harsh environment. Better Heat Dissipation Aluminium shell improve better heat dissipation effect and sturdiness to extend service life. SMT Process SMD components with high integration, high reliability, high stability makes it better control. Wide Applications Th ese compact size dc voltage reducer converters are high reliability power transformers. They can work safely and reliability within temperature range -40°C~80°C. Widely used to golf cart, motor, speaker, GPS, LED car display screen, air-conditioner, electric fan, solar energy, photo-voltaic power, DVD, industrial equipment ect. If the converter does not work, please check this following steps 1. Please to check whether the power supply has voltage 2. Whether the terminals are in poor contact and whether the wire ends are connected securely 3. Please to check whether the wires are installed as shown in the pictures and instructions. If the wires are not installed correctly, the voltage regulator will not work If all the above are correct, please reach out us and we will solve your problem immediately. PLEASE NOTICE 1. The input voltage should not exceed the fluctuation range of the converter can withstand. 2. The converter output power must be greater than output nonnection device required power. 3. Positive and negative wires can't be reversed connection. Review: I would recommend - No problem with performance here. Can maintain 3A output. Was able to do 3A constant current load even at 5V (says it's good to 8V). Efficiency was around 85% to 91% depending on input and output. At 2A output (for hours), the unit is warm to the touch but not hot. Solid converter that costs a little more than the cheaper ones, but the performance makes it well worth it. Review: Easy to work with, runs cool - I'm using this to run my network router off of a DIY solar-powered battery backup. The router is designed for a 12V power supply and pulls 13W max. I didn't want to risk the charging voltage of 14.6V frying the router (it would probably be fine, but...) so I have this DC-DC converter hooked to the load terminals of the solar charge controller. The converter runs cool, but then again I'm hardly pushing it. Hookup was easy- I just inserted the stripped ends of one pair into the SCC terminals, and crimped an Anderson connector onto the other. There are mounting holes on the converter, but I just used double-sided foam tape to attach it to the battery box. ## Features - Input Voltage: DC 12V/24V/36V nominal, Voltage Range: 8V-40V; Output Voltage: DC 12V 3A 36W ; Maximum Efficiency:≥95%; Ripple Wave: 50Mv; Starting delay time:≤2s. - Protection: Built in over-load, over-current, over-temperature and short-circuit protection. - Design: Aluminium shell with epoxy potting, waterproof, anti-dust, anti-shock protection and better heat dissipation. - Application: Widely used in golf cart, club car, car audio, LED strip lights, monitoring system, advertising screen, motor, dashcam, truck, emu and DIY etc. - Guarantee:These voltage converters are excellent power transformers, can work safely and reliable in -40°C~80°C range.

Can maintain 3A output. Was able to do 3A constant current load even at 5V (says it's good to 8V). Efficiency was around 85% to 91% depending on input and output. At 2A output (for hours), the unit is warm to the touch but not hot. Solid converter that costs a little more than the cheaper ones, but the performance makes it well worth it. ### ⭐⭐⭐⭐⭐ Easy to work with, runs cool *by S***L on November 6, 2023* I'm using this to run my network router off of a DIY solar-powered battery backup. The router is designed for a 12V power supply and pulls 13W max. I didn't want to risk the charging voltage of 14.6V frying the router (it would probably be fine, but...) so I have this DC-DC converter hooked to the load terminals of the solar charge controller.

I got this to regulate the input to a backup camera. It introduced a lot of flicker in the video so, wasn’t appropriate for that application. ## Frequently Bought Together - Protooma DC Voltage Converter - Regulator Boost Buck Converter Reducer 8V-40V Step Up Down to 12V 3A 36W for Golf Cart Club Car LED Light,Waterproof Power Supply Transformer Volt Module - 3 Gang Toggle Rocker Switch Panel Red LED Breaker Waterproof Widely Fits for Auto Automotive Lights Car Marine Boat Yacht, Trailer, Caravan, Camper, Bus, Tractor, Jeep, Truck Vehicles & More --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/476279482-dc-voltage-converter-regulator-boost-buck-converter-reducer-8v-40v](https://www.desertcart.tn/products/476279482-dc-voltage-converter-regulator-boost-buck-converter-reducer-8v-40v) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-01*
