Easy System Integration — Standard RS485 with Modbus protocol for remote monitoring and centralized control.
The Z2400-45G/55P is widely used in:
Air compressors — stable pressure control with PID
Pumps and fans — energy-saving variable torque operation
Conveyors and material handling — smooth start/stop with S-curve ramp
Textile machinery — precise speed regulation in dense wiring environments
CNC and machine tools — reliable torque output for spindle and feed drives
Metallurgy, building materials, and mining — enhanced stability under harsh conditions
The Z2400 series upgrades the proven Z2000 platform with a focus on stability and interference resistance in heavy-duty operations. It features high-quality IGBT modules and optimized thermal design, enabling continuous full-load operation at up to 45°C ambient temperature. The series also includes momentary power-loss ride-through and rapid current limit functions, significantly reducing nuisance tripping caused by grid fluctuations or sudden load changes.
1. What does the model “45G/55P” mean?
A: “45G” refers to 45 kW for constant torque (heavy-duty) applications, while “55P” refers to 55 kW for variable torque (fan and pump) applications. One drive covers both duty types, giving you greater flexibility across different loads.
2. What is the overload capacity and starting torque?
A: The Z2400-45G/55P delivers 150% rated current for 60 seconds and 180% for 3 seconds (G type). It also provides 150% rated torque at 0.5 Hz, ensuring reliable startup and stable operation under heavy loads.
3. Does it support PID control and remote communication?
A: Yes. It features built-in PID constant-pressure control and standard RS485 communication with Modbus protocol, making it easy to integrate into centralized monitoring and automation systems.
4. Can it operate continuously at full load, and what is the maximum ambient temperature?
A: Yes. The Z2400 series is designed for continuous full-load operation at ambient temperatures up to 45°C, with optimized thermal design and high-quality IGBT modules for enhanced stability.
5. What certifications, warranty, and ordering terms do you offer?
A: The product is CE certified and comes with an 12-month professional warranty. MOQ is 1 unit, lead time is 7–30 days depending on quantity, and payment can be made via T/T or PayPal. OEM/ODM inquiries are welcome.
