As a dedicated manufacturer with over a decade of expertise in electrical equipment, Jinhua Dika Electrical Equipment Co., Ltd. proudly presents our Automatic Voltage Stabilizer series. Designed specifically for demanding industrial environments, these stabilizers in 30kVA, 50kVA, and 100kVA capacities provide a robust solution for converting 220V input to a stable 380V output. Our commitment to quality, backed by a comprehensive ISO management system framework, ensures that every unit delivers reliable performance to protect your valuable machinery and ensure operational continuity.
Our Three Phase Automatic Voltage Stabilizers are engineered to address the critical need for consistent voltage in industrial applications. Fluctuations in power supply can lead to equipment malfunction, reduced efficiency, and even permanent damage. This product actively corrects these variations, providing a safeguarded power environment.
- Core Technology & Operation: The stabilizer employs an advanced microprocessor-based control system that continuously monitors the input voltage. Upon detecting a deviation from the nominal 220V, it automatically adjusts the output through a series of regulated steps to maintain a precise 380V supply. This process is seamless and instantaneous, preventing any disruption to connected loads.
- Construction & Durability: Built with industrial-grade components, the unit features a sturdy enclosure designed for longevity. Key internal components include high-efficiency magnetic cores and precision winding coils, ensuring minimal energy loss and high tolerance to electrical stress.
-
Key Features & Benefits:
- Automatic & Continuous Regulation: Eliminates the need for manual intervention, providing uninterrupted voltage correction.
- High Capacity for Heavy Loads: The 30kVA, 50kVA, and 100kVA models are capable of supporting large industrial motors, CNC machines, production lines, and other high-power equipment.
-
Comprehensive Protection Suite: Integrated safeguards protect both the stabilizer and your equipment:
- Overload Protection: Shuts down output if connected load exceeds capacity.
- Short Circuit Protection: Instantly isolates the stabilizer in case of a fault.
- Over-voltage & Under-voltage Protection: Prevents output voltage from exceeding safe limits.
- User-Friendly Interface: Options include a digital LED display showing input/output voltage, load percentage, and system status, facilitating easy monitoring.
- Flexible Cooling: Designs are available with natural convection or forced air cooling fans to suit different installation environments and duty cycles.

Frequently Asked Questions (FAQ)
-
Q: What is the primary application for this Three Phase Stabilizer?
A: It is primarily designed for industrial settings where three-phase equipment (like large motors, industrial pumps, manufacturing machinery) operates on a 380V supply but is fed from a 220V grid or source, requiring voltage stabilization and conversion. -
Q: How does the "Automatic" feature work?
A: The stabilizer uses a digital control board that samples the input voltage thousands of times per second. If it deviates from 220V, the system automatically commands servo motors or electronic switches to adjust the transformer tap positions, correcting the output to 380V without any manual operation. -
Q: Can this stabilizer handle voltage spikes or surges?
A: While its primary function is correction of gradual variations, the unit includes basic over-voltage protection that will disconnect the output if the input spike exceeds a safe threshold. For severe surge protection, additional external devices may be recommended. -
Q: Is installation complex?
A: Installation involves connecting the input and output power cables, which is straightforward for qualified electricians. We provide detailed wiring diagrams and manuals. The physical mounting depends on the model size—larger units may require floor placement. -
Q: What is the difference between the 30kVA, 50kVA, and 100kVA models?
A: The key difference is the maximum load they can support. kVA (kilo Volt-Ampere) indicates capacity. You should select a model based on the total power consumption (kVA or kW) of all equipment you intend to connect to it, with some margin for safety. -
Q: Does it work with both 50Hz and 60Hz power systems?
A: Yes, the core design is compatible with both frequencies. The specific model can be configured or selected at the time of order to match your local grid frequency. -
Q: What kind of maintenance is required?
A: Routine maintenance is minimal. It primarily involves keeping the unit clean, ensuring ventilation paths are unobstructed, and periodically checking connection tightness. The internal electronic components are designed for long-life operation. -
Q: Are custom specifications available?
A: As a manufacturer, we can discuss modifications such as different input/output voltage ranges, special enclosure requirements (like higher IP ratings for dusty environments), or integration of remote monitoring interfaces. Please inquire for customization options.
