AC drive for pump and fan application
Shenzhen Powtran Technology

1).Can save 20%-50% energy of your motor
2).Power range: 0.75-11 KW
3).Input voltage: 1 phase AC, 220V,3 phase AC--380V,
460V,575V, 660V-(fluctuating :15% )
4).Output voltage:3 phases 220V-660V.
5).Output frequency range:0--800hz.
6).Has protection of over current, over heat, over voltage, over load, less voltage and less load.
7).Central control module based on DSP(digital signal processing),realizes high-speed and perfect performance control.
8).Integrate V/F control ,V/F+PG control .
9).3 produce ways of spacial voltage vector waveform
10).Dead area compensation function, realize low frequency and big torque control.
11).Automatic slip compensation.
12).At most 7 steps speed control and 8 steps acceleration control can be realized.
13).6 programmable output control terminals.
14). PID function, realize high performance closed loop control.
15).Support feedback signal of DC 0-10V,1-5V,0-20mA and 4-20mA.
16).Built-in PID regulate DC braking.
17).Automatic tracking speed and starting and restart after momentary power loss.
18).Forceful communicated function, support standard RS485, and remote keyboard control.
