HI-SAVER Features


Before Installation
• Starts with initial control panel Y-Δ.
• Generates 3-6 times the starting current
• Starts at FULL SPEED regardless of load variation, leading to high energy consumption
• Unable to control power during peak hours.
• Irregular load quantity with the use of power factor control capacitors.
• Unreasonable increase in contracted power with expansion
• Unable to control airflow and water flow
After Installation
• Enables SOFT START
• Starts within 100% of the rated current
• Reduces PEAK power due to starting current, extending motor life.
• Energy saving with load control by inverters
• High power control with increased PEAK reduction effect
• Easy automatic control of load with power control
30% reduction in contracted power
• Precise control of air and water flow

Technical Effectiveness 

Annual electricity bill savings of 20-50%; with a reduction of 30-50% starting from the 2nd year
Reduction in apparent power leads to lower contracted power and basic charges 
Eliminates the need for power factor improvement capacitors 
Noise is stringently filtered 
Easy proportional output control on the drive load side 
Enhanced product competitiveness 
Increased equipment lifespan 
Improved safety
