With a rapid response time of 500 ms for voltage variations, it protects your equipment while being built to endure high vibration levels. This product is specifically tailored for low voltage alternators and is proudly made in France, complete with a 2-year international warranty. ## Description If generators put out weak or inconsistent voltage outputs, it can cause severe damage to the equipment they power. The Leroy Somer R250 ensures that you get a consistent output from your generator, keeping your equipment safe and saving you from the costs involved in repairing and replacing your equipment.World-class qualityThe Leroy Somer AVR R250 is produced by French company Leroy Somer. This company is the largest producer of AC alternators in the world. Every component in the unit is individually factory tested and certified -- so you can be sure you are getting a voltage regulator of the highest quality, built by world leaders in the field.Stable voltageThe AVR R250 works by controlling the excitation current. The exciter is the part of the generator that turns the rotor and generates electricity. If the excitation current is not consistent, the generator will not produce a stable voltage. The Leroy Somer R250 sits by your generator and monitors its output. When the voltage dips, the R250 increases the exciter current. Likewise, should the voltage increase, the AVR R250 will reduce the exciter current.Key specifications: Voltage regulation: -0.5% to +0.5%Adjustable voltage and stability settingsThe power supply is protected by an 8 A fuse with a breaking capacity of 30 kA - U/F and LAM functionsSupply range/voltage detection from 85 to 139 V (50/60Hz) Optional remote voltage potentiometerI.E.C 60034-1 standard compliantU.L. 508/C.S.A. approvedCan be safely operated in temperatures ranging from -40Β°C to +70Β°CKey Points:Same day Worldwide ShippingOriginal Leroy Somer R250 AVRP.N AEM110RE019Largest AVR Stock in USA ## Features - Ensure stable output from your generator and protect your equipment - Well suited to harsh conditions and high vibration levels - Fast response time -- kicks in within 500 ms for 20% voltage variations - Designed for low voltage alternators with a SHUNT excitation - Power controlled by transistors ## Images ![R250 AVR | 100% Original | 2 Year International Warranty | Official Leroy Somer Distributor | Leroy Somer P/N AEM110RE019 | 100% Made in France - Image 1](https://m.media-amazon.com/images/I/71X565Lu5UL.jpg) ![R250 AVR | 100% Original | 2 Year International Warranty | Official Leroy Somer Distributor | Leroy Somer P/N AEM110RE019 | 100% Made in France - Image 2](https://m.media-amazon.com/images/I/71SG1JALXlL.jpg) ![R250 AVR | 100% Original | 2 Year International Warranty | Official Leroy Somer Distributor | Leroy Somer P/N AEM110RE019 | 100% Made in France - Image 3](https://m.media-amazon.com/images/I/61bbB6ifBBL.jpg) ![R250 AVR | 100% Original | 2 Year International Warranty | Official Leroy Somer Distributor | Leroy Somer P/N AEM110RE019 | 100% Made in France - Image 4](https://m.media-amazon.com/images/I/61NteFW+eaL.jpg) ![R250 AVR | 100% Original | 2 Year International Warranty | Official Leroy Somer Distributor | Leroy Somer P/N AEM110RE019 | 100% Made in France - Image 5](https://m.media-amazon.com/images/I/61AKSguGDNL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Awesome!! Original is the way to go! *by A***R on November 16, 2017* Installed this on my LS 43.2 back end easy to install adjust it to 480V 3phase and worked like a charm! Don’t buy the other cheap clones you see for less than $100, recently purchased one of those aftermarket Chinese ones and it burned up. This is the original! called General Power after the purchase and confirmed for myself. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/72666561-r250-avr-100-original-2-year-international-warranty-official-leroy](https://www.desertcart.vn/products/72666561-r250-avr-100-original-2-year-international-warranty-official-leroy) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-20*
