WD400WD400 Series AC Drive (CE, UL, EAC)
International Grade AC Drive WOLONG WD400

WD400 is a general-purpose vector AC drive rated 0.75–710 kW for export applications: supply 1 × 200–240 V, 3 × 380–480 V and 3 × 660–690 V, V/F, SVC and FVC control of induction and permanent magnet synchronous motors. Speed range 1:500, steady speed accuracy ±0.5 % (SVC) and ±0.02 % (FVC), torque accuracy ±3 % and ±2 % respectively, starting torque 200 %, overload 150 % for 60 s. Safe Torque Off (STO) is built in; the drive complies with CE, EAC, UKCA and RoHS, which simplifies supply of equipment into the EAEU.
