ZONCN Z2400-75P is a high-performance vector VFD from the Z2000 series, engineered for square torque loads such as large fans and water pumps. Rated 75kW, 3-phase 380V~440V, with 150A rated output current. This P-type drive delivers stable speed regulation and remarkable energy-saving performance for medium & large industrial fluid equipment, ideal for retrofitting existing fixed-speed systems and new project deployment.
Built with sensorless vector control algorithm, the drive maintains steady output under fluctuating load conditions. Integrated IPM power modules lower heat generation and extend service life. It comes with rich built-in functions including PID closed-loop regulation, multi-speed preset, automatic voltage stabilization (AVR) and stall protection, simplifying system configuration without extra PLC hardware.

FAQ

Q1: What does P-type mean for Z2400-75P?

A: P variant is optimized for square torque loads like fans and pumps, featuring energy-saving logic and matched overload capacity, different from G-type constant-torque models for heavy machinery.


Q2: What motor can this VFD drive?

A: It matches 75kW three-phase asynchronous motors, widely used for water pumps, blowers and similar fluid equipment.


Q3: Can it work with unstable grid voltage?

A: Yes. The built-in AVR function automatically stabilizes output voltage when mains power fluctuates within ±15% of rated voltage.


Q4: What protections are included?

A: It includes over-current, over-voltage, under-voltage, over-temperature, phase loss and short-circuit protection to prevent sudden equipment damage.


Q5: What about delivery and packaging?

A: Standard models have short lead time. Packed in sturdy carton with foam cushioning. Sea freight, air freight and express shipping are available.


Q6: Can you help with parameter debugging?

A: Our technical team offers remote support via video or email for commissioning and parameter setting. Operation manuals are provided for onsite reference.
