SAFESAVE SN360 Series 400V-750V solar pump frequency inverter is a high quality, multi-function SVC inverter, based on the European power and latest control theoretical and technological achievements and combining with the latest market power technology application requirements. By decoupling control of motor magnetic flux current and torque current torque to reach fast response and accurate control, you can run a wide range of speed and torque control in high-precision.
◎ Control system: AC frequency vector control based the high performance of DSP.
◎ Control method: V/F control, vector control for flux with open loop 1, vector control for flux with open loop 2, vector control for PG.
◎ Lifting function of automatic torque: Torque control for low frequency (1Hz) and great output in the control method of V/F.
◎ Control on accelerating and decelerating: Setting method for subsections of accelerating and decelerating S curve; the longest operation time 9600h.
◎ Control on programme operation: Operation for speed program of 16 sections; the longest operation time: 888.88h.
◎ V/F curve method: User defines V/F curve for linear and multiple power
