Product Overview

The ZONCN Z2400-37G/45P is a high-performance three-phase 380V vector variable frequency drive (VFD) engineered for industrial motor speed regulation and energy-saving operation. With a dual power rating design, this single unit supports both 37kW constant torque (G-type) for heavy-duty equipment and 45kW variable torque (P-type) for fans, pumps, and ventilation systems - one drive, multiple applications.

Product features

1. Dual Power Rating - One Drive, Two Applications

The Z2400-37G/45P uniquely combines 37kW G-type for constant torque loads (conveyors, mixers, machine tools) and 45kW P-type for variable torque loads (fans, pumps, ventilation). This eliminates the need to purchase two separate drives, reducing procurement costs and simplifying inventory management.


2. High-Precision Vector Control

Advanced Sensorless Flux Vector Control (SFVC) delivers 150% high torque output at 0.5Hz, with speed regulation accuracy up to ±0.5% and speed ratio of 1:100. This effectively resolves low-speed jitter and insufficient power issues common in traditional VFDs.


3. Intelligent Energy Saving

Built-in intelligent energy-saving algorithms automatically adjust output power based on real-time load changes, reducing equipment energy consumption by 20%-40%. Ideal for continuous-duty industrial operations where electricity costs represent a significant portion of total operating expenses.


4. Wide Voltage Adaptability

Supports 3-phase 380V AC input with ±15% voltage fluctuation tolerance, ensuring stable operation even in unstable power grid environments. Suitable for various regional industrial power supply conditions worldwide.


5. Robust Industrial Design

Automatic Voltage Regulation (AVR) : Maintains constant output voltage during mains fluctuations

Auto Voltage/Over-Current Stall Control : Prevents frequent tripping by automatically limiting current and voltage during operation

Rapid Current Limit : Avoids over-current faults and extends drive lifespan

DC Braking : 0.0Hz to maximum frequency, braking time 0.0-100.0s


6. Flexible Control Functions

16 Preset Speeds via simple PLC function or X terminal combination

Onboard PID for process-controlled closed-loop systems

4 Groups of Acceleration/Deceleration (0.0-6500.0s), straight-line and S-curve ramp modes

Multi-Point V/F Curve , N-power V/F curve, complete/half separation options.
