Special Frequency Converters (electrostatic precipitator power supplies) (15KW/18.5KW)

Reliability:

• The entire product range conforms to the national standard open-grade EMC testing standards and has obtained the CNAS system certification certificate and authentication record number.
• Generous margin design, rigorous testing and validation, selection of high-quality components, and meticulous process management to ensure long-term reliable operation of the product.
• The entire product line adopts an encapsulated IGBT module solution, effectively ensuring product consistency and reducing quality blind spots.
• Three-channel current sampling enables precise torque control while effectively protecting against abnormal conditions such as overcurrent, short circuits, and grounding.
• Robust switch power protection design ensures product stability under any auxiliary power instantaneous/continuous short-circuit conditions.
• The product utilizes original German Peters three-proof paint, along with a two-coat application process, to ensure reliable operation in complex environments.

Structural properties:

• Direct independent air duct design, and spatial isolation, maximizes heat dissipation capability and support compact installation of multiple units in parallel.
• The entire series is equipped with high-speed DC fans, offering extended lifespan and easy replacement.
• Optional dust cover plates and dust screens (supporting quick installation) are available to effectively reduce the impact of dust and moisture on the product.
• Models with a power rating of 160KW and above support cabinet mode, enabling rapid and cost-effective cabinet assembly.

Characteristics of the software:

• Multiple control modes such as V/F, open-loop vector, closed-loop vector, and pressure frequency separation are available with deeply optimized software performance, making it suitable for a wide range of application environments.
• Supports static and dynamic self-learning modes, enabling rapid and accurate acquisition of motor parameters.
• Upon power-up, automatic ground detection is performed on the power output line (including the motor), enabling comprehensive protection for both the inverter and motor.
• Optimized speed tracking function, supports one-to-one or one-to-many tracking start, effectively reducing the start-up surge current.
• Rapid suppression function for over-current and over-voltage ensures uninterrupted operation in the event of sudden load fluctuations.
• Supports parameter copying, enabling rapid batch debugging of similar functional requirement environments.

Expanded Features:

• Supports a variety of encoders, including differential signal and open collector signal.
• Supports 2/3 channels of 0~10V analog isolated inputs.
• Supports 2/3 channels of 0~1V analog isolated inputs.
• Supports 2/3 channels of 0~10V or 0~1A combined analog isolated inputs.
• We are soon launching a programmable I/O expansion card that can serve as a cost-effective alternative to small PLCs, effectively reducing system costs for our customers.
