Applications
- Mining processing plants, conveyor drives, and underground VFD motor controls in Western Australia & Queensland.
- Solar PV inverter stations, wind farm balance of plant, and battery energy storage system (BESS) connections.
- Data centers, commercial hospital towers, and telecom facilities with heavy UPS and switching power supply loads.
Features
- Optimized low-loss foil/transposed winding architecture minimizing stray eddy current losses caused by high-frequency harmonic currents.
- Heavy-duty 200% rated copper neutral conductor and terminal prevents overheating from 3rd, 9th, and 15th harmonic currents.
- Grounded copper electrostatic shielding attenuates high-frequency common-mode electrical noise and switching transients.
