AS2 Series is a compact panel-mount V/F inverter for machines that need variable speed but not vector control. It covers 0.4 to 7.5 kW on single-phase 220 V and three-phase 380 V supplies, with natural convection cooling and a keypad an operator can learn in ten minutes.
Power input lands on L1/L2 or L1/L2/L3, the motor connects to U/V/W, and two-wire start-stop uses the FWD, REV and COM control terminals. There is no cooling fan, so there is no filter to clean and no fan to replace.
0.1-400 Hz output covers 50 Hz and 60 Hz motors and higher-speed blower duties
V/F control with linear, multi-point and square V/F curves
150% starting torque and 150% overload for 60 s (G type)
Built-in PLC for eight-speed operation, plus built-in PID and AVR
Over-current stall control limits current instead of tripping on heavy starts
4-digit LED keypad with speed potentiometer; natural convection, panel mount, IP20

Conveyors: set belt speed once, adjust with the knob when the product changes
Water pumps: replace valve throttling with speed control, PID holds the pressure setpoint
Fans and blowers: square V/F curve matches variable-torque duty
Processing equipment: mixers, small extruders, packaging lines with eight preset speeds
Send us the motor nameplate - power, voltage, phases, full-load current and the duty - and we will confirm the right model and lead time. Sample orders and OEM branding are available.
