AD350 sensorless vector control frequency inveter

AD350 High Performance Sensorless Vector Control Frequency Inverter

AD350 high performance vector control mini frequency inverter is KEWO independently developed new generation general purpose electrical motor controller, which adopt the same software platform as same as AD800.
With a new generation of high-performance advanced vector control technology applying, high torque control even under low speed, high speed precision, quick torque response and high speed range are available for sophisticated motor control.
It is featured to have modular design, small size, small temperature rise, low noise, and reliable performance. It has built in simple PLC, PID adjusting, programmable input and output terminals function, RS458 terminals, multi function analog input and output function. ect.
Power range: 2S 0.4 to 2.2kw, 4T 0.75 to 3.7kw.
Input voltage: Single phase 220V, 3 phase 380V ±15%
Control mode: Sensorless vector control without PG, V/f control
Protection function: Provide up to 25 kinds fault protection, over current, over voltage, under voltage, phase missing, overload protection function
Cooling method: force cooling
Installation method: wall mount
Infineon iGBT module for good quality

Products features:
AD350 inverter has the same software and same operation manual as AD800.
Only some hardware, the size and I/O layout is difference.

*AD350 sensorless vector control inverter can’t performance close loop vector control because there are no PG connector.

AD100/AD350 frequency inverter application examples.
1. Food processing machinery
Bakery equipment, confectionary equipment, tea-making machine, noodle-making machines, candy-wrapping machines, rice/barely milling machines, flour milling machines, food mixers, food slicers, fruit sorting machines, etc.
Advantage:
l You can set the operating frequency according to the required work rate.
l Run and Stop keys.
l Ensures safety in the event of an instantaneous power failure.
l Low noise
l High torque from start up to the rated speed.
2. Conveyance machinery
Conveyors, automatic warehousing systems etc. Prevent the collapse of cargo on the conveyor.
The AD100/AD350 allow you to mitigate the shocks caused in starting and stopping a conveyor and change the acceleration /deceleration rates according to the conveyor characteristics and its applications.
The AD100/AD350 can slow down a high –inertia machine in a short period of time without causing an overvoltage trip by increasing the energy consumed by the motor.
The AD100/AD350 can turn on and off the braking circuitry in accordance with the inverter operating status.
It offers vector control and automatic torque boost control modes to achieve strong, stable torque from the start of a motor to the rated speed.
3. Fans & pumps
Built in fans- pumps in industrial machines, water supply and sewage systems, driers, etc.
Energy-saving mode
The variable torque and automatic energy saving modes help saving energy by passing optimal current in accordance with the load.
Automatic process control
Allows a motor to keep running and accelerate smoothly upon the recovery of power even in the event of instantaneous power failure.
Enable an uninterrupted operation without causing a trip.
4 Health, medical and nursing care equipment.
Stair lifts, nursing bed, bubble baths, health care equipment, medical equipment
5. Environment and daily-life-related machinery
Commercial ironing boards, car washing machines, Garbage disposers, dust collectors, Dries, etc.
6. Packing machinery.
Inner packaging machine, packing machines, output packing machines, membrane packing machines
