Contact UsAs a premier manufacturer and international exporter of high-performance AC Drives (Variable Frequency Drives / VFDs) and total power distribution systems, we supply custom-engineered 400V/415V 50Hz solutions designed specifically for New Zealand's unique industrial matrix.
New Zealand’s industrial landscape demands exceptional equipment reliability. From the high-throughput dairy processing plants of the Waikato to the geothermal energy installations of the Taupō Volcanic Zone, continuous process uptime hinges on electrical control precision. AC Drives (Variable Frequency Drives) play a pivotal role in optimizing energy utilization, eliminating mechanical shock loads, and suppressing line harmonics across 3-phase electric motor networks.
Our operational architecture combines decades of power conversion engineering expertise with bespoke OEM/ODM manufacturing. We supply specialized low-voltage (230V to 690V) and medium-voltage (3.3kV to 10kV) AC Drive systems equipped with advanced Vector Control, Direct Torque Control (DTC), and Active Front End (AFE) regeneration capabilities. Every export configuration destined for Auckland, Tauranga, Christchurch, or Wellington ports undergoes comprehensive factory acceptance testing (FAT) to verify performance under localized environmental and electrical grid stress parameters.
Tailored drive topology engineered to survive humidity, corrosive geothermal gases, coastal salt fog, and continuous heavy washdown operations.
In high-volume dairy processing sites (e.g., Waikato, Taranaki), AC drives manage multi-stage centrifugal pumps, milk separators, and high-inertia spray dryer exhaust fans. Our IP66 stainless-steel drive cabinets withstand rigorous CIP (Clean-In-Place) washdowns and chemical exposure while delivering precise PID flow control.
New Zealand's geothermal plants (Taupō and Bay of Plenty) expose electrical hardware to atmospheric hydrogen sulfide (H2S). Our AC Drives feature conformal coating (Class 3C3/3S3 standard) on all internal PCBs, housed within IP54/IP65 sealed control cabinets to prevent sulfur-induced circuit corrosion.
Forestry processing facilities in Kinleith and Kawerau demand massive starting torque and quick deceleration for heavy sawlogs and chippers. Our heavy-duty vector AC drives incorporate high dynamic torque limits and regenerative braking units to feed excess energy back into the plant power loop.
Over the Canterbury Plains, large-scale center-pivot irrigation systems rely on deep-well pump controllers. We manufacture solar-compatible MPPT VFD drives that switch seamlessly between PV solar arrays and grid power, mitigating water hammer via soft-start ramp curves.
Port operations in Auckland and Lyttelton mandate zero-downtime gantry cranes and winch controls. Our Active Front End (AFE) low-harmonic AC drives ensure compliance with strict port power quality codes while delivering anti-sway positioning accuracy.
Commercial high-rises in Wellington and Christchurch leverage our BACnet and Modbus embedded AC drives for variable air volume (VAV) air handlers and chilled water pumps, reducing facility energy usage by up to 45%.
Navigating the transition toward complete electrification, grid harmonic mitigation, and energy conservation regulations.
New Zealand's Energy Efficiency and Conservation Authority (EECA) and the Electricity Authority (EA) have tightened regulations surrounding total harmonic distortion (THD) and motor system efficiency. Modern industrial capital expenditure projects require AC drives that conform to AS/NZS 61000.3.12 for harmonic emissions and support IE4/IE5 Super Premium efficiency synchronous reluctance motors.

Combining 38+ years of global power system design with tailored OEM customization and direct export capabilities.
Our manufacturing history spans nearly four decades of pioneering research in power conversion, high-power rectifiers, transformer isolation, and variable frequency drive algorithm design.
We do not just ship catalog items. Over 50% of our production volume consists of engineered-to-order drive cubicles, custom control software mapping, and multi-voltage distribution skid packages.
Every AC Drive assembly undergoes rigorous thermal chamber stress-testing, 100% full-load burn-in, insulation resistance verification, and high-voltage dielectric withstand testing prior to packing.
Common inquiries regarding international shipping, technical standards compliance, installation support, and drive sizing.
While standard Asian and European drives are nominal 380V or 400V, all our export AC drives built for New Zealand feature wide-input voltage tolerance (380V to 440V ±15% continuous rating at 50Hz). This eliminates over-voltage tripping during light load periods on rural 415V distribution lines and guarantees full motor shaft output performance.
We provide multiple harmonic mitigation tiers: standard integrated dual DC reactors, external 3-phase passive LCL filters, and Active Front End (AFE) regenerative drive units. Our AFE drive arrays limit total current harmonic distortion (THDi) to under 5%, easily satisfying the strict requirements of major NZ lines companies (such as Vector, Orion, and Powerco).
Standard standalone VFD drive units are stocked for immediate export dispatch within 5-7 business days. Custom-engineered drive control cabinets, ATS assemblies, or step-down distribution transformer packages typically require 3 to 4 weeks for production and testing, followed by fast ocean freight or direct air freight to major NZ ports.
Yes. Every industrial AC Drive system supports native RS485 Modbus RTU/TCP. We also offer factory-fitted option cards for DNP3 (Outstation Level 2 standard in power utility applications), Profinet, EtherNet/IP, and BACnet for seamless connection into Allen-Bradley, Siemens, or Schneider automation architectures.
We maintain comprehensive engineering documentation, parameter mapping sets, and modular spare power cards (IGBT modules, gate drivers, control boards) for at least 15 years after product series phase-out. Technical support is provided directly by senior application engineers who understand AC drive hardware and field application conditions.
