Frequently Asked Question
A: Servo stabilizers use electromechanical control with 1-3 second response time and ±2-3% accuracy. IGBT static stabilizers offer ultra-fast ≤10ms response, ±1% precision, and no mechanical wear, making them ideal for critical applications.
A: Our stabilizers feature independent phase control with automatic balancing. Each phase is regulated individually while maintaining proper phase relationships, correcting imbalances up to ±1% between phases.
A: Our largest single cabinet unit is 3000KVA. For higher capacities, we design parallel systems with multiple units. We’ve successfully installed systems exceeding 10MVA using modular parallel configurations.
A: Yes, we manufacture for all global standards including 380V (Europe/Asia), 415V (UK/Australia), 480V (North America), and custom voltages. Each model is optimized for its specific voltage system.
A: Comprehensive protections include over/under voltage, phase loss, phase imbalance, overload, short circuit, over-temperature, and surge protection. Advanced models add harmonic filtering and arc fault detection.
A: Our industrial models feature redundant components, advanced thermal management, continuous duty ratings, and preventive maintenance alerts. We conduct 168-hour burn-in testing for critical applications.
A: We provide complete installation support including site surveys, electrical drawings, installation supervision, and commissioning services. Our engineers ensure proper integration with existing electrical systems.
A: Yes, our systems support parallel operation with automatic load sharing and redundancy. N+1 configurations ensure continuous operation even if one unit requires maintenance.
A: Advanced models include Ethernet, Modbus, CAN bus communication, SCADA integration, remote monitoring capabilities, and comprehensive data logging for predictive maintenance.
A: Industrial systems include 2-year comprehensive warranty with optional extended coverage. We provide global service network, spare parts availability, preventive maintenance programs, and 24/7 emergency support.
