Power Capacitor for PFC

Power Capacitor for PFC

The power Capacitor for PFC is a self-healing type low voltage shunt capacitor that is made of advanced metalized film and is produced strictly in accordance with IEC. This power factor capacitor is suitable for low-voltage power networks to improve power factor reduce reactive loss and better voltage quality.
