Product Overview
APF active power filter is intended for harmonic control and power quality improvement. It is commonly used for harmonic control and reactive power compensation, with the final selection based on rated data, drawings, and site conditions.
electrical contractors, industrial plant engineers, EPC companies, maintenance teams, and project distributors can request configuration review for active power filter. Please send system voltage, compensation or filtering capacity, control logic, monitoring requirements, cabinet quantity, and wiring diagram, quantity, destination, and any project standard requirements for quotation.

Installation Dimensions / Drawing
ForAPF, confirm the cabinet outline, ventilation space, wiring path, component arrangement, and control interface drawing. Use the confirmed technical table, project drawing, and site installation plan as the final dimensional reference before ordering or installation.
Applications
APF is mainly selected for harmonic control and reactive power compensation. The final application should match the confirmed active power filter, rated data, and site installation conditions.
- Harmonic control
- Reactive power compensation
- Industrial projects requiring power quality improvement
Ordering Instructions / Information Required for Quotation
ForAPF, send system voltage, compensation or filtering capacity, control logic, monitoring requirements, cabinet quantity, and wiring diagram, quantity, destination, and the expected delivery schedule. The engineering review will be based on the selected active power filter and project drawing.
ORDERING INSTRUCTIONS
- State the required APF configuration, quantity, project destination, and intended application.
- Provide rated voltage, required capacity or current, control logic, wiring diagram, cabinet quantity, and installation environment for technical review.
- Confirm the cabinet outline, ventilation space, wiring path, component arrangement, and control interface drawing before final production or installation planning.
- List any special environmental, wiring, communication, metering, protection, or component requirements in the inquiry.
