Power Factor Controller
Power Factor Controller
Dubas Engg Pvt. Ltd. offers Power Factor Controller. It is an active solid state power factor controller capable of correcting both displacement and distortion power factors, compensating the reactive current drawn by the load with a priority to correct displacement power factor. It improves the power factor to near unity (>0.99) dynamically. Since it is an active compensator, compensating both inductive and capacitive (+ and -) reactive power is achieved. This avoids dangers of resonance and overcompensation like in thyristor switched capacitor banks. Power factor capacitors are fully eliminated in this configuration. Systems can also be programmed and set to provide a specified PF if desired.
- Fully DSP controlled digital systems, compensation is done within 10 to 20 msec (< 1 cycle)
- Highly reliable and advanced IGBT based PWM technology
- Ideal system to achieve near unity PF (>0.99) to take full advantage of incentives provided by electric utility companies. Can also be programmed to achieve any specified reference PF
- Avoids dangers of over compensation and resonance
- No overheating of cables and components
- Increased life of all components / equipment in the connected electrical network
- Avoids stray tripping of breakers and protection relay
- Avoids flickers, sags and surges
- Reduced Demand charges and reduced tariff
- Full utilization of sanctioned demand
- Three phase currents in the network also gets balanced to a large extent by ePFC
