Medium Voltage VFD WD1000 — WOLONG
WD1000WD1000 Series High-Performance Engineering Drive (690 V / 1140 V)

Medium Voltage VFD WOLONG WD1000

WOLONGManufacturer: WOLONG

WD1000 is Wolong's engineering drive for 690 V and 1140 V systems, rated 315–5600 kW. The inverter uses ANPC (active neutral point clamped) technology and is three-level in the C and CL versions; inverter efficiency exceeds 98.6 % and diode rectifier efficiency exceeds 99.2 %. Control modes are VVVF, SVC and FVC with a range up to 1:1000, starting torque 200 % at 0 Hz, peak torque 150–250 %, torque response under 5 ms. One controller drives up to three vector axes or eight scalar axes and supports a common DC bus. Air or water cooling, noise below 75 dB.
