Applying the most advanced sensorless vector control technology , 32bits DSP control system and Infineon latest IGB technology, Excellent unique ventilation design with powerful big fans. More than 2000pcs AD800 high performance vector control inverters are widely using in kinds application since 2014 with good customer feedback.

Specification:

(AD100, AD350, AD800, AD800S)
Single phase, 220V, 0.4kw to 2.2kw. Three phase, 220V, 0.75kw to 75kw
Three phase, 380V/660V/1140V, 0.75 to 630kw.

Product feature:

It has V/F, OLV( open loop vector control ), CLV ( close loop vector control), Compatible with variety of encoder such as collector, differential / rotary transformer . 

1). Wide speed control range 
a). Sensorless open loop vector (OLV) control: 0.5 to 400Hz ( 1:100/50Hz datum point )

b) . Sensor with PG card: 0.5 to 400Hz ( 1:100/50Hz datum point) Good current waveform.

2). Response speed improving
Adopting high speed 32 bit DSP to get the high speed response of frequency inverter.
a)  The response 100rad/s, precision ± 0.5% in sensorless open loop vector control mode.  
b). The response 250rad/s, precision ± 0.01% in sensor close loop vector control mode.

3). High torque output under low speed to meet some big inertia load conditions
High torque under low speed achievement. Adopting advanced current vector control technology and motor parameters detecting to make high torque under low speed is available.

4). Torque control in OLV and CLV

5). Powerful PID function 

6). Stall protection function 

7). Speed tracking restart function
Detect motor speed and rotation direction automatically, no any trip during start even in reverse running status.

8). S curve function 

9).16 segment speed circle running, easy to configure.

10). Advanced energy saving technology

AD800 series inverter can detect the load status to control the output voltage and power factor to make motor work in high efficient mode.
