The BK-ZHB570 series (3 Phase) heavy-duty industrial frequency inverter y variable frequency drive (VFD) is a high-performance current vector AC drive specifically engineered for heavy-duty industrial applications requiring three-phase power supply. As a professional frequency converter y inverter drive, it is ideally suited for driving general-purpose three-phase AC asynchronous motors, and excels in powering equipment with high starting impact, continuous heavy loads, and rigorous operational demands—such as industrial crushers, large ball mills, heavy-duty elevators (equipped with dedicated elevator drive), hydraulic presses, steel rolling mill auxiliaries, and mining conveyors (matched with specialized conveyor drive).

This three-phase heavy-duty VFD supports two advanced control modes: voltage-to-frequency ratio control (V/F control) and sensorless vector control (SVC). As a reliable frequency inverter, it boasts an overload capacity of 1.5 times the rated current, outstanding low-frequency high-torque output performance (150% rated torque at 0.25Hz in SVC mode), and a comprehensive fault protection mechanism (including overcurrent, overvoltage, undervoltage, overheating, phase loss, and short-circuit protection). Designed to adapt to three-phase grid characteristics, this AC drive can effectively withstand grid voltage fluctuations, minimize equipment energy losses, and significantly enhance the operational stability and energy efficiency of large-scale industrial production.

Its core design focuses on high reliability, robust environmental adaptability, and precise control under heavy-duty conditions. Through optimized heat dissipation structures, reinforced circuit layouts, and industrial-grade component selection, this frequency converter ensures long-term stable operation in harsh industrial environments—such as high-temperature workshops, dusty mining sites, and humid processing plants—meeting the uninterrupted operation demands of critical industrial processes.

✅ FAQs – 75–160kW Three-Phase Variable Frequency Drive (VFD)

Q1: What industrial systems typically use a 75–160kW VFD?
This high-power range powers mission-critical applications such as:

Municipal water booster & wastewater lift stations (100–200 HP pumps)
Large screw or centrifugal air compressors in manufacturing plants
Mine hoists, crushers, and long-distance conveyors
Cooling water circulation in power plants or data centers
Extrusion lines and rolling mills in metal/plastic processing
These systems demand continuous operation, high torque at low speed, and minimal downtime.

Q2: Can a single 160kW VFD replace multiple smaller drives?
Yes—and it often reduces total cost of ownership. For multi-pump headers or parallel fan arrays, one 160kW VFD with built-in multi-motor control logic can synchronize operation, simplify wiring, and cut panel space by up to 40%. However, redundancy-critical systems may still prefer N+1 smaller units.

Q4: Is harmonic mitigation included for utility compliance?
Standard units include a built-in DC choke (reducing THD to ~20–30%). For sites requiring THD <5% (per IEEE 519), we offer factory-integrated options:

12-pulse diode front-end + phase-shifting transformer
Active Front End (AFE) with near-unity power factor
Both solutions avoid costly external filters and simplify grid approval.
