Universal Variable Frequency Drive

CHF100A series high performance Universal Variable Frequency Drive is the enhanced edition of CHF series, which is combined the advantage of CHF100 & CHE100. It adopts the DSP control system supplies sensorless vector control and V/f control. The performance is more perfect and stable. It is widely applied in Pump & Fan and some applications with high speed control accuracy, rapid torque response and high performance at low frequency.
Features
1.Three control modes: without PG vector (SVC), V/F control, and torque control;

2.Starting torque: without PG vector control: 0.5Hz/150% (SVC);

3.18.5kW-90kW inverter built-in DC reactor to improve input power factor and increaseoverall efficiency and stability;

4.Internal brake unit with every specification 0.75-15kW, so that the braking resister can be connected directlyfor a quick stop;

5.16-steps simple PLC, multi-speed control, and PID control;

6.Supporting multi-frequency installation methods: digital setup, analog quantity setup, PID setup, and communication setup;

7.Supports starting and stopping DC brake;

8.The input and output terminals may be freely programmed, so users may combine a variety of operating modes as needed;

9.Equipped with jump frequency control which prevents mechanical resonance and makes the system more stable and reliable;

10.Equipped with instantaneous power failure non-outage capability;

11.Equipped with sleep-wake delay installation capability;
