Automatic Power Factor Correction (APFC) panels are electrical devices designed to improve the power factor of electrical systems. They automatically adjust the reactive power in a circuit, helping to reduce energy costs and improve the efficiency of electrical equipment. APFC panels are typically constructed from durable materials such as steel or aluminum and are equipped with capacitors, contactors, and control circuits to manage power factor correction effectively.
| Material | Steel or aluminum enclosure |
| Voltage rating | Up to 690V |
| Power factor correction range | 0.8 to 1.0 |
| Capacitance range | 1 kVAR to 1000 kVAR |
| Control type | Microprocessor-based or relay-based |
| Protection features | Overcurrent, short circuit, and surge protection |
When selecting an APFC panel, consider the specific power factor requirements of your electrical system. It's important to specify the desired power factor correction level, the voltage rating, and the total kVAR needed. Additionally, inquire about the control type, as microprocessor-based systems offer more advanced features. Ensure that the panel meets relevant industry standards and certifications for safety and performance.
