AUTOMATIC VOLTAGE REGULATOR FOR POWER SUPPLY
Product Description
A single-phase automatic voltage regulator is a device used to adjust the voltage of single-phase AC power, mainly composed of a single-phase autotransformer, an on-load tap changer, an automatic controller, etc. It can adjust the input unqualified voltage to a stable and qualified output voltage to meet the voltage demand of the load. It is mainly used in power systems, industrial production, and other fields. It is widely used in Central America and Australia, and the product is mature and reliable.
Main Technical Parameters
Features of Products
Product Features: Single-Phase Automatic Voltage Regulator (AVR) for Power Supply Systems
1. Advanced Voltage Regulation Technology
* Real-Time Correction: Continuously monitors input voltage and provides instantaneous correction (±0.5% to ±1% output accuracy) through electronic switching or tap-changing mechanisms.
* Wide Input Voltage Range: Compensates for ±15% to ±25% input voltage variations while maintaining stable output (e.g., 120V/230V ±1%).
* Fast Dynamic Response: Reacts to voltage fluctuations within 1.5 to 2.5 cycles (20-40 milliseconds), ensuring critical loads remain unaffected by sags or surges.
* Multiple Correction Methods:
Electronic (Solid-State): IGBT/Power MOSFET-based for seamless, step-less correction (0-100% of range)
Electromechanical: Servo-motor driven variable transformer for high-current applications
Hybrid Designs: Combine electronic pre-regulation with tap-changing for optimal efficiency
2. Intelligent Control & Protection Systems
* Digital Signal Processor (DSP) Control:
* Adaptive Algorithms: Self-adjusting compensation based on load characteristics and line conditions
* Programmable Voltage Profiles: Time-based, temperature-compensated, or load-dependent setpoints
* Harmonic Filtering: Built-in passive/active filtering to reduce THD to <3%
* Comprehensive Protection Suite:
* Input/Output Surge Protection: 10-40 kJ surge withstand capability (per IEEE C62.41)
* Overload & Short-Circuit Protection: Electronic current limiting with automatic recovery
* Phase Loss & Reversal Detection: Immediate shutdown on abnormal phase conditions
* Over-Temperature Protection: Multi-zone thermal monitoring with graded response
3. Enhanced Operational Features
True Online Double-Conversion (for UPS-grade AVRs):
* Zero transfer time between input and regulated output
* Complete isolation from input disturbances and noise
* Energy Efficiency Optimization:
* Eco-Mode Operation: Bypasses regulation during normal input conditions (efficiency up to 98%)
* Sleep Mode**: Reduces standby consumption to <0.5% of rated power
* Power Factor Correction: Maintains >0.95 lagging/leading PF across load range
* Modular & Scalable Design:
* Hot-Swappable Power Modules (for parallel redundant systems)
* Field-Expandable Capacity: 20-100% scalable without downtime
4. Connectivity & Smart Grid Integration
Industry 4.0 Ready:
* Dual Communication Ports: RS-232/485, Ethernet (Modbus TCP/IP, SNMP)
* Cloud Connectivity: Built-in IoT gateway for remote monitoring via web/mobile apps
* Predictive Maintenance: AI-based algorithms analyzing performance trends
* Grid Support Functions:
* Demand Response Capable: Automatically adjusts voltage setpoints based on grid signals
* PV/Frequency Support: Compatible with solar inverters and microgrid applications
* Data Logging: 10-year event history with 1-minute resolution trending
