Description
The AVR LS R250 Automatic Voltage Regulator is a compact, reliable, and high-performance voltage controller, tailored specifically for use with small to mid-range generator sets. Built for consistency, the R250 AVR ensures that your generator delivers clean, stable voltage output, regardless of load variation or operating conditions.
Designed for LS Alternators and Stamford-type generators, this regulator is a smart choice for gensets ranging from 5 kVA to 30 kVA. Whether you're powering a shop, a small industrial setup, a commercial property, or backup systems at home, the R250 AVR plays a crucial role in safeguarding your equipment and improving generator efficiency.
At the heart of its function is precision voltage regulation, offering an impressive ±1% voltage stability. This helps protect sensitive appliances and machinery like pumps, compressors, lights, computers, and medical equipment from voltage spikes, surges, or brownouts. In locations where power fluctuation is common, installing this AVR significantly enhances power reliability and reduces maintenance cost for your entire electrical system.
The AVR LS R250 uses shunt excitation, which is highly efficient for its capacity class and simplifies installation. It requires no external power supply, drawing excitation directly from the generator output. Its air-cooled design provides efficient heat dissipation, allowing stable performance even during extended operation.
A key feature of the R250 is its auto-frequency sensing. Whether your generator operates at 50 Hz or 60 Hz, this AVR will automatically detect and adapt without the need for manual settings. This makes it a versatile option for mobile generators or units used in different regions or industries.
Installation is plug-and-play, with clearly labeled terminals and compact size that fits easily inside generator control boxes or panels. The unit also includes potentiometers for voltage adjustment, allowing quick tuning to match your generator’s voltage output to the connected load's needs.
One of the biggest reasons customers prefer the AVR LS R250 is its excellent price-to-performance ratio. For a budget-friendly cost, it delivers reliability, safety, and long-term protection for generators and electrical equipment. It's widely used by electricians, generator service providers, and OEMs for its quality and ease of use.
