Protections: Over-current, Over-voltage, Over-temperature, Over-load and Short-circuit, auto-recovery when device is back to normal operating. 5. Certificates: CE/RoHS, 1 year warranty, lifetime up to 100,000 hours. Package included: 1 x DC 12V/24V - 5V 30A Voltage Converter Questions: 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. ## Features - Input voltage range: DC 10-30V; Output voltage: DC 5V(non-adjustable); Output current: 30A; Output power 150W. - High conversion efficiency: Synchronization rectification technology-multiple intelligent protection function with high conversion efficiency and stability. The conversion efficiency may reach 95%. - Protections: Over-load, Over-current, Over-temperature, Short-circuit, Over-voltage. - Aluminum shell and silicone sealed design: Waterproof, Anti-shock, Anti-humidity and Dust-proof, more durable. - Wide application: Large trucks, taxi radio, emu, car audio, LCD TV, advertising screen, LED strip lights, monitoring system, motor, electronic systems and DIY etc. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07VGN79X5 | | Best Sellers Rank | #282,243 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #1,199 in Power Converters | | Brand | Cllena | | Color | Silver,Black | | Customer Reviews | 4.6 out of 5 stars 3 Reviews | | Input Voltage | 30 volts | | Item Weight | 5 ounces | | Manufacturer | Cllena | | Mfr Part Number | DC1205-30 | | Number of Outlets | 1 | | Output Voltage | 5 volts | | Power Source | Battery Powered | | Total Power Outlets | 1 | ## Product Details - **Brand:** Cllena - **Input Voltage:** 16 Volts - **Output Voltage:** 24 Volts - **Power Source:** Battery Powered ## Images ![DC 12V 24V Step Down to 5V 30A 150W Converter Voltage Regulator, Waterproof DC/DC Buck Transformer Power Supply - Image 1](https://m.media-amazon.com/images/I/71jQ3A+pljL.jpg) ![DC 12V 24V Step Down to 5V 30A 150W Converter Voltage Regulator, Waterproof DC/DC Buck Transformer Power Supply - Image 2](https://m.media-amazon.com/images/I/71RtVeQLdEL.jpg) ![DC 12V 24V Step Down to 5V 30A 150W Converter Voltage Regulator, Waterproof DC/DC Buck Transformer Power Supply - Image 3](https://m.media-amazon.com/images/I/71uLYOKdSmL.jpg) ![DC 12V 24V Step Down to 5V 30A 150W Converter Voltage Regulator, Waterproof DC/DC Buck Transformer Power Supply - Image 4](https://m.media-amazon.com/images/I/61N63-QPA6L.jpg) ![DC 12V 24V Step Down to 5V 30A 150W Converter Voltage Regulator, Waterproof DC/DC Buck Transformer Power Supply - Image 5](https://m.media-amazon.com/images/I/711AVswO0kL.jpg) ## Available Options This product comes in different **Size** options. --- ## 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.lk/products/509206947-dc-12v-24v-step-down-to-5v-30a-150w-converter](https://www.desertcart.lk/products/509206947-dc-12v-24v-step-down-to-5v-30a-150w-converter) --- *Product available on Desertcart Sri Lanka* *Store origin: LK* *Last updated: 2026-09-03*
