If the input supply is not capable of providing the power, the converter will fold back the output voltage as necessary. Example: If your load draws 3A at 3V (9W), and the input supply is only capable of providing 12V at 0.5A (6W), the maximum output voltage the converter will deliver is 2V (6W/3A).Package includes:1X 12V to 3V 3A Mini DC-DC Step Down Converter ## Features - Converts a 12V input voltage (will operate with any input voltage from 8V to 24V) to 3V DC (+10% -0%) output at up to 3A - Up to 9W output power (3V at 3A) - Fully sealed and waterproof - Overload / over-current / over / low voltage protection, stable performance - The inputs and outputs are labeled on the sticker on top of the converter, the red and black wires are the + and - 12V input, and the red and yellow wires are the + and - 3V output. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07PNWPLRY | | ASIN | B07PNWPLRY | | Best Sellers Rank | #28,391 in Electronics ( See Top 100 in Electronics ) #395 in International Power Adapters | | Brand Name | Envistia | | Current Rating | 3 Amps | | Customer Reviews | 4.6 4.6 out of 5 stars (244) | | Customer reviews | 4.6 4.6 out of 5 stars (244) | | Date First Available | 29 August 2019 | | Is Discontinued By Manufacturer | No | | Item Dimensions D x W x H | 38D x 27W x 230H millimeters | | Item Weight | 30 Grams | | Item model number | 3V 3A DC-DC Converter | | Manufacturer | Envistia | | Manufacturer | Envistia | | Model | 3V 3A DC-DC Converter | | Mounting Type | Surface Mount | | Part Number | 3V 3A DC-DC Converter | | Power Source | DC Power Supply | | Product Dimensions | 3.8 x 2.7 x 23 cm; 30 g | | Specification Met | UL | | UPC | 732387204855 | ## Product Details - **Brand:** Envistia - **Current rating:** 3 Amps - **Mounting type:** Surface Mount - **Power source:** DC Power Supply - **Product dimensions:** 38D x 27W x 230H millimeters ## Images ![Envistia Mall 12V to 3V 3A Step-Down Waterproof Miniature DC-DC Converter Power Supply Module by - Image 1](https://m.media-amazon.com/images/I/61QiTvq2r4L.jpg) ## Questions & Answers **Q: What guage are the wires?** A: The manufacturer doesn't specify the wire gauge, but the wire conductor has a diameter of 1mm (0.04 inches), which would make it 18 AWG wire. **Q: is this a switching DC-DC converter (or linear converter)?** A: It's a switching converter. Power output at 3V is roughly equal to power input at 12V, so the input current is much lower than the output current. Minimal dissipation compared to a linear converter. **Q: So, if i have a device that takes 3v .225a, even though this outputs a max of 3a it should work fine?** A: Yes, absolutely. This module is voltage-regulated, meaning it regulates the output to 3V, and will provide whatever current the load draws, up to 3A maximum. ## Frequently Bought Together - Envistia Mall 12V to 3V 3A Step-Down Waterproof Miniature DC-DC Converter Power Supply Module by - HOMELYLIFE DC 12V 24V to DC 5V 3A 15W Step Down Buck Converter Voltage Regulator Reducer Power Converter Mini Module Transformer - DC 12V/24V to 5V 3A Step Down Converter - 12V Voltage Regulator Buck Converter Power Supply Transformer - 12V/24V to 5V 3A --- ## 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/343402550-envistia-mall-12v-to-3v-3a-step-down-waterproof-miniature](https://www.desertcart.tn/products/343402550-envistia-mall-12v-to-3v-3a-step-down-waterproof-miniature) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-22*
