EC Fan Driver

An EC fan refers to a fan that uses an EC (Electronically Commutated) motor as its drive unit. It combines the high-efficiency and intelligent characteristics of EC motors with the aerodynamic design of fans, serving as an integration of high energy efficiency and intelligent control. Relying on its significant energy efficiency advantages, precise speed regulation, and long service life, it has become a mainstream choice in the field of modern ventilation and heat dissipation. From building HVAC (Heating, Ventilation, and Air Conditioning) systems to industrial equipment, and from new energy to high-end manufacturing, its application scenarios continue to expand. Especially in the era of pursuing low carbon and intelligence, it is becoming a key component for energy-saving upgrades across various industries.

Technical Specifications

● Power: 0.75-30W, single-phase 220V, three-phase 380V

● TI 32t high-speed DSP main control chip

● IP65 potection rating

● High power factor design

● Active PFC design

● Design meets UL certification requirements

● Reserved STO interface

● Optional 5/7ment waveform generation, supporting up to 16carrier frequency, with low motor resonance and low noise

● Built-in high-performance underlying algorithms (SVC, VVC+) for permanent magnet synchronous motors, featuring strong robustness

● Wide-range speed regulation: Supports smooth speed adjustment from 0 to 50Hz (or higher frequency), and can adjust the fan speed according to the real-time heat dissipation needs of the refrigeration system (such as changes in condensation temperature and ambient temperature)

● Soft start and soft stop: The speed rises gradually from 0 during startup (the starting current is only 1-2 times the rated current), avoiding the large current impact caused by the "instant full-speed startup" of fixed-frequency fans

● Avoid "overcapacity operation": Traditional fixed-frequency fans have a fixed air volume, often resulting in redundant energy consumption where "the designed air volume far exceeds the actual demand". The inverter can save 20%-60% of energy by dynamically matching the air volume

● Wide temperature range and corrosion resistance: The operating temperature range is extended to -10℃~60℃ (the heating module starts at low temperatures), and the PCB board is coated with UV paint to resist moisture and salt spray corrosion

● Remote control: Supports communication protocols such as RS485 and Modbus, and can be connected to PLC, SCADA systems or IoT platforms to realize remote speed adjustment and status monitoring

● Compatible with multiple fan types: Supports mainstream fans such as axial flow fans, centrifugal fans, and Roots fans, and is compatible with asynchronous motors and permanent magnet synchronous motors

● No need to replace the fan: Can directly replace traditional fixed-frequency controls (such as contactors, relays); during transformation, only the motor wires and control wires need to be connected, making installation simple

● Local control: Manually adjust the speed through the panel knob and buttons
