Certificates: CE/RoHS, 1 year warranty, lifetime up to 100,000 hours. Package included: 1 x DC 40V/90V to12V 20A 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. Review: Does an excellent job protecting my expensive electronics - I purchased this to use for my Iceco VL60D in hopes that it will give it a longer life. The compressor is much quieter and the refrigerator runs much smoother. The voltage regulator stays really cool... It always feels room temperature and works perfectly. I believe that this is a great purchase to protect my large investment of the refrigerator.

However, if you hook each one to a 1 ohm ceramic resistor each, then connect them together. The issue is that each one will want to be at a slightly different voltage and they’ll fight each other. You need to buffer that difference with a resistor on each of them. **Q: Large spark when conncting 72v battery normal?** A: Yes, it is normal to get a rather unnerving spark when connecting the converter to the battery. **Q: What in the input amperage required?** A: That would depend on the AMP draw of the output, and the voltage of the input. You can probably find a good calculator by googling. **Q: what is the exact output voltage and can it be adjusted?** A: The exact voltage is 12,4V and don’t have no ajustement ## Customer Reviews ### ⭐⭐⭐⭐⭐ Does an excellent job protecting my expensive electronics *by R***N on November 10, 2025* I purchased this to use for my Iceco VL60D in hopes that it will give it a longer life. The compressor is much quieter and the refrigerator runs much smoother. The voltage regulator stays really cool... It always feels room temperature and works perfectly. I believe that this is a great purchase to protect my large investment of the refrigerator. ### ⭐⭐⭐⭐⭐ Great product *by V***D on November 12, 2025* Works Great !! ### ⭐⭐⭐⭐ Works perfectly to convert 15 VDC to a stable, regulated 12 VDC - 3A! *by B***K on June 24, 2024* Repurposing an old Verizon FiOS battery backup power supply sounded good, not so much when I measured the output voltage! To my surprise, the labeled 12 VDC output voltage measured over 15 VDC! My search to find a converter to drop the 15 VDC to a stable... regulated 12 VDC found this one! The pros: + Reasonable price of $14.24, with free Amazon Prime 2nd day delivery! + Good customer product reviews for the 12 VDC - 3 A converter & regulator. + I like not having to adjust the output voltage, it's preset & not adjustable! The cons: - Made in China, for those that prefer to but product made in the USA. - The wire leads are on the thick side, which made crimping on Molex .062 connectors tricky, but doable! Closing remarks: ▪ With 15.28 VDC in from the old Verizon FiOS battery backup power supply, the output was a stable, regulated 12.28 VDC... perfect! ◄ see my attached picture! ▪ To my surprise, the "huge" heat sink stays cool to the touch! ▪ I didn't want to drill holes, so I opted to use foam double sided tape to attach the heat sink. ◄ see my attached picture! ▪ The Cllena 8-40 VDC >to> 12 VDC - 3 A, down converter & regulator is used to power the auto shutdown control valve on our RO - reverse osmosis water filtration system. ◄ see my attached picture. ▪ I ordered 2 more of these for a couple other projects I have on the "to do" list! ## Frequently Bought Together - Cllena DC 40V-90V to 12V Converter Voltage Regulator Reducer 48V 60V 72V Step Down to 12V 20A 240W Converter Waterproof Buck Transformer Power Supply for Golf Cart Club Car LED Light - Battery Adapter for EGO 56V 10 Gauge 2FT Lithium Output Dock Power Connector ONEWHEEL --- ## 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.jp/products/362153079-dc-40v-90v-to-12v-converter-voltage-regulator-reducer-48v](https://www.desertcart.jp/products/362153079-dc-40v-90v-to-12v-converter-voltage-regulator-reducer-48v) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-05-18*
