Information

Product Overview

The YIMAI DVR Series Automatic Voltage Regulator is an advanced microcomputer-controlled voltage stabilizer engineered to provide precise, stable power for electrical equipment in regions with poor grid quality. Utilizing high-speed electronic switching and servo-motor control technology, this AVR automatically adjusts input voltage fluctuations (typically 90V~260V AC) to a precise 220V±1% output, protecting sensitive devices from damage caused by over-voltage, under-voltage, and power surges. Available in 5kVA, 8kVA, and 10kVA capacities, it is the ideal solution for homes, small businesses, and light industrial applications.

Core Technical Advantages

Microcomputer-Controlled High-Precision Regulation

The voltage stabilizer employs an advanced microprocessor to monitor and adjust voltage in real time, achieving a regulation accuracy of ±1% and a fast response time (<0.5 seconds). This ensures a stable 220V output even when the input voltage fluctuates drastically, protecting sensitive electronics from damage.
Ultra-Wide Input Voltage Range

It accepts an ultra-wide input voltage range (typically 90V~260V AC), making it suitable for areas with extremely unstable power grids, where voltage often drops below 100V or spikes above 250V. This wide range ensures continuous operation even under the most extreme power conditions.
Real-Time LCD Monitoring & Display

The front panel features a clear color LCD display that shows real-time input voltage, output voltage, load percentage, and operating status. It also provides visual and audible alarms for fault conditions (over-voltage, under-voltage, overload), allowing users to easily monitor power quality and detect abnormalities at a glance.
Comprehensive Multi-Layer Protection Mechanisms

The system is equipped with a full suite of built-in protections:
- Over-voltage protection (OVP): Automatically cuts off power when output voltage exceeds safe levels.
- Under-voltage protection (UVP): Disconnects the load when input voltage drops below the minimum threshold.
- Over-load protection (OLP): Shuts down to prevent damage when the load exceeds the rated capacity.
- Short-circuit protection: Safeguards against short circuits in the connected equipment.
- Surge & lightning protection: Filters out high-voltage spikes caused by lightning or grid switching.
- Over-temperature protection: Prevents overheating of internal components.
Efficient & Durable Design
- Uses high-quality copper coils and magnetic cores, ensuring low energy loss and high efficiency (>90%).
- The robust metal enclosure provides excellent heat dissipation and mechanical protection, extending the service life to 10+ years.
- Low noise operation (<55dB) makes it suitable for home and office environments.
Compact & Easy Installation

The compact, wall-mountable design saves valuable floor space. It features plug-and-play operation, with input and output terminals for quick connection to various devices. No complex wiring or configuration is required, making installation quick and hassle-free.
