High Reliability & Performance / Compact / Energy Saving
LSIS medium voltage drive consists of compact integrated systems built on cutting-edge technologies, delivering optimum energy-saving solution featuring high efficiency and power factor. The system supports a user-friendly HMI(Human Machine Interface) that allows easy operation and displays desired information for customers maximum convenience. LSIS medium voltage drive offers leading industrial drive solutions with proven reliability and economic viability. It also contributes to energy saving and environment protection in various industries including gas, water treatment, marine, power generation, and cement.
Improved Power Quality
Improved Input Power Quality and THD (Total Harmonic Distortion) by Adopting Multi-winding Phase-shift Transformer
Producing Multilevel PWM-type Sinusoidal Output
Achieving Energy Saving and Minimum Energy Loss through Optimized Speed Control
Guaranteeing High Operating Efficiency and Power Factor
Cell Bypass Function
Automatically bypass of failed cells if cells connected in series randomly fail during operation, allowing continuous operation.
Automatically estimates speed of the rotating motor to reach the frequency without any system failure(trip)
Mechanical energy of load is regenerated to continue operation for up to 5 cycles when power outage occurs. It allows continuous operation without stopping the drive or system.
Synchronous Transfer Function
Switching motor power from medium voltage drive to commercial power (bypass mode) or vice versa (drive mode)
Standard HD HMI Monitoring Maximizes User Convenience
