Due to the large fluctuation of ac voltage, the recommended ac voltage range has been reserved. - The power module adopts plug-in LM2596HV, LM2596 version of high voltage, the highest input voltage is 50V(limited by filter capacitor voltage) with external radiator, can withstand high current work. - Input voltage range: AC 5V-30V, DC 5V-50V Output output range: DC 3.3V-33V ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B094ZTG5S8 | | Best Sellers Rank | #162,916 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #662 in Power Converters | | Brand | UMLIFE | | Color | 4 PCS | | Customer Reviews | 4.1 4.1 out of 5 stars (164) | | Input Voltage | 50 volts | | Item Weight | 3.84 ounces | | Manufacturer | UMLIFE | | Model Number | 701715466395 | | Number of Items | 4 | | Number of Outlets | 4 | | Output Voltage | 33 volts | | Plug Type | Type A | | Power Source | Dc Power Supply | | UPC | 701715466395 | | Unit Count | 4 Count | ## Product Details - **Brand:** UMLIFE - **Color:** 4 PCS - **Input Voltage:** 50 volts - **Item Weight:** 3.84 ounces - **Output Voltage:** 33 volts ## Images ![4PCS AC/DC to DC Step Down Buck Converter AC 5-30V DC 5-48V 24V 36V 48V to DC 2.5-35V 12V Voltage Regulator Board 2A Adjustable Volt Power Supply Module - Image 1](https://m.media-amazon.com/images/I/71WT5ASrcBS.jpg) ## Available Options This product comes in different **Color** options. ## Questions & Answers **Q: Need 5vdc out, input varies 7-15vac...will it regulate at 5vdc out or will it be proportional to varying 7-15 input** A: They are very precise about the output. I used on with 12 v input and 5v output for an arduino. When I connected it to 24v - still, exactly 5v! **Q: Will this modual go from 12v ac in to 3v dc out ?** A: Yes **Q: Is there a UL Listing for this?** A: You don’t need one. If you’re going to embed this into a system then the system gets UL approval. That’s the point of an embedded system. **Q: Can this convert 24v ac to 24v dc or will there be a drop across the device?** A: This conversion broad has worked great for me. My demands are not great , I can get the DC voltages I need. I recommend! ## Frequently Bought Together - UMLIFE 4PCS AC/DC to DC Step Down Buck Converter AC 5-30V DC 5-48V 24V 36V 48V to DC 2.5-35V 12V Voltage Regulator Board 2A Adjustable Volt Power Supply Module - HiLetgo 2pcs 5V One Channel Relay Module Relay Switch with OPTO Isolation High Low Level Trigger - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects --- ## 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.co.th/products/331208210-4pcs-ac-dc-to-dc-step-down-buck-converter-ac](https://www.desertcart.co.th/products/331208210-4pcs-ac-dc-to-dc-step-down-buck-converter-ac) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-10-08*
