THE PERFECT HVAC SOLUTION BETWEEN CONTROL AND ENERGY SAVINGS
Schneider Electric's Altivar 21 variable speed drive bagged the 2008 European HVAC Electric Drives Technology Innovation Award. Known for the best harmonics reduction drive, Altivar 21 yields great energy savings. This breakthrough re-emphasised Schneider Electric's technological superiority within the industry.
Key functional principles for reducing harmonics
- Optimise power section
- Reduce DC bus capacitance value to 3% of an equivalent standard AC drive DC bus capacitance
- Input current waveform modified reducing current spikes observed during the capacitor charging cycle
Powerful algorithm and processor
- Less DC bus capacitance makes more DC ripple on the DC bus
- New motor control processor and algorithm manage the ripple and produce sinus current waveform to the motor
Benefits
- Harmonics reduction complies to IEC 61000-3-12 without additional chokes
- Reduced cost and size
- Flexible and easy integration
- Increase energy efficiency
