Understanding Automatic Voltage Regulators
Learn how YOKE AVRs protect your equipment from voltage instability and power fluctuations.
SVC Series - Servo Motor Voltage Stabilizers
SVC (Servo Voltage Control) series regulators use a servo motor mechanism to adjust voltage. When input voltage fluctuates, the servo motor automatically moves the carbon brush along the autotransformer winding to maintain stable output voltage. YOKE SVC regulators offer excellent voltage regulation accuracy (±2-3%) and fast response times. Available in capacities from 3KVA to 60KVA, these units are suitable for both residential and light industrial applications where reliable voltage stabilization is critical.
SVC Series Key Features
TND Series - Digital Display Voltage Stabilizers
TND series voltage regulators feature digital LED or LCD displays showing input and output voltage in real-time. These models use advanced electronic control circuitry for faster response times and more precise voltage regulation compared to traditional SVC models. The digital display allows users to monitor voltage conditions at a glance, making TND series ideal for environments where visibility and monitoring are important. Available in various capacities with compact designs suitable for desktop or wall mounting.
TND Series Key Features
Why Voltage Stabilization Matters
Voltage fluctuations and power surges are common problems in many electrical grids worldwide. Unstable voltage can cause serious damage to electrical equipment, leading to costly repairs or premature equipment failure. A quality voltage regulator like YOKE AVRs ensures that your appliances and equipment receive consistent, safe voltage levels regardless of input fluctuations. This extends equipment lifespan, reduces downtime, and saves money on repairs and replacements.
🔌 Over-Voltage Protection
Voltage spikes can instantly destroy sensitive electronics. YOKE AVRs detect and correct over-voltage conditions within milliseconds.
⚡ Under-Voltage Protection
Low voltage causes equipment to overheat and fail prematurely. YOKE AVRs boost under-voltage to safe operating levels.
AVR Capacity Selection Guide
Selecting the right capacity is crucial for effective voltage regulation. The AVR capacity should exceed your total load by 20-30% to account for startup currents and future expansion. For inductive loads (motors, compressors), allow 3-5x the running wattage for startup.
| AVR Model | Capacity | Recommended Use | Max Current |
|---|---|---|---|
| SVC-3000VA | 3KVA / 2400W | Home appliances, computer, TV | 13A |
| SVC-10KVA | 10KVA / 8KW | Small office, shop, multiple rooms | 40A |
| SVC-30KVA | 30KVA / 24KW | Large office, light industrial | 120A |
| SVC-50KVA | 50KVA / 40KW | Production lines, workshop | 200A |
| SVC-60KVA | 60KVA / 48KW | Heavy industrial, large machinery | 240A |
