• ±2% High Precision Output Accuracy: Advanced servo motor control and dual high conductivity carbon brush technology enable precise voltage regulation with industry leading ±2% output accuracy, ensuring connected equipment receives stable power within tight tolerances at all times.
• 150KVA Full Capacity Output: Engineered with full purple copper column windings and high grade transformer core material, this regulator delivers genuine 150KVA rated capacity without false power rating, supporting heavy inductive, capacitive, and resistive loads simultaneously.
• 415V±20% Wide Input Regulation Range: Accepts input voltage fluctuations from 332V to 498V (415V±20%) while maintaining stable output, providing robust protection against severe grid instability commonly encountered in industrial zones and remote locations.
• Comprehensive Ten Function Protection Suite: Integrated protection mechanisms against over voltage, under voltage, overload, short circuit, over temperature, phase sequence reversal, phase loss, frequency deviation, neutral line disconnection, and time delay faults safeguard both the regulator and all downstream equipment.
• Intelligent LCD Real Time Monitoring: A multifunctional LCD display panel provides clear real time visualization of input voltage, output voltage, load current, operational status, and fault diagnostic codes, with intuitive on screen buttons enabling straightforward parameter configuration without external tools.
• Switchable Bypass and Regulation Modes: Built in manual bypass switching allows maintenance operations or direct grid passthrough when voltage conditions are stable, providing operational flexibility and reduced wear during normal grid conditions.
• Industrial Mobility and Thermal Design: Integrated heavy duty brake wheels enable easy repositioning within factory floors, while the optimized ventilation structure and heat dissipation channels maintain safe operating temperatures even under continuous full load operation at up to 45°C ambient conditions.

This 150KVA three phase voltage regulator excels in a broad range of industrial and commercial applications. Manufacturing facilities rely on it to protect CNC machine tools, injection molding equipment, and automated production lines from voltage surges that could cause tool path errors or motor damage. Data centers and server rooms deploy these units to maintain stable power for critical IT infrastructure, preventing data corruption and hardware failures caused by power anomalies. Photovoltaic power stations and generator based off grid systems utilize the regulator to condition irregular output before feeding distribution panels. Medical imaging equipment, laboratory analytical instruments, and precision measurement devices benefit from the clean sinusoidal output waveform with zero additional harmonic distortion. Telecommunications base stations, broadcasting equipment, and railway signaling systems also depend on this voltage stabilizer for uninterrupted reliable operation in remote and electrically noisy environments.

Each SBW-150KVA voltage regulator undergoes rigorous full function testing before shipment, including load testing under rated capacity, protection function verification, and extended burn in operation to ensure zero defect delivery. The unit is securely packed in a reinforced export grade wooden case with internal shock absorbing foam padding and moisture barrier wrapping to withstand long distance ocean, air, and land transportation.
