Variable Frequency Drive Control Cabinet for Fans

• Strict compliance with ISO9001:2015 Quality Management System Certification

• Equipped with international standard certifications.

Modular design integrating variable frequency drive (VFD), current transformers, and multi-function meters

PID algorithm enables stepless motor speed regulation (0-50Hz), achieving 30%-60% energy savings compared to traditional damper control

Independent cooling system maintains efficient heat dissipation for VFD motors at low speeds, preventing overheating issues common in conventional motors

Standard molded-case circuit breakers and fuse bases provide dual protection against short-circuit/overload, supporting continuous operation for fans below 55kW

Embedded intermediate relays and fault indicator lights in power distribution box

Real-time feedback on overload, phase loss, etc., with response time ≤0.1s

Temperature controller with IP55-rated cabinet automatically activates cooling fans (-20℃~50℃ operating range)

Optional harmonic filters extend equipment lifespan by 2+ times by suppressing PWM-induced electromagnetic interference

Aviation plug quick-connect solution simplifies field installation

Manual/auto mode toggle switch compatible with DCS remote monitoring

Drawer-type design enables hot-swap maintenance of VFD modules (average fault recovery time reduced to 15 minutes)

0.5-grade precision energy measurement via ammeter/CT combination for data-driven efficiency optimization

Widely used in subway ventilation, factory dust removal, etc.

Multi-brand VFD compatibility (e.g., Siemens, ABB)

Optional soft starters reduce motor inrush current to 150% (75% less grid load than traditional methods)

Full series CCC certified with customizable cabinet sizes and protection levels
