SVC Cooling 3 Phase Inverter 380V / 220V CHF100A series , Invt Inverter Chf100A
Brief Introduction
CHF100A series 3 Phase inverter 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) Supporting multi-frequency installation methods: digital setup, analog quantity setup, PID setup, and communication setup;
2) Three control modes:
2.1) without PG vector (SVC);
2.2) V/F control;
2.3) and torque control.
3) QUICK/JOG function: users can freely define multi-functional shortcut keys, and by setting up these parameters users can quickly browse different function codes of modified which are different from default values;
4) Starting torque: without PG vector control: 0.5Hz/150% (SVC);
5) 18.5kW-90kW inverter built-in DC reactor to improve input power factor and increaseoverall efficiency and stability;
6) Internal brake unit with every specification 0.75-15kW, so that the braking resister can be connected directlyfor a quick stop;
7) 16-steps simple PLC, multi-speed control, and PID control;
8) Equipped with instantaneous power failure non-outage capability;
9) Supports starting and stopping DC brake;
10) The input and output terminals may be freely programmed, so users may combine a variety of operating modes as needed;
11) Offering a variety of fault protection functions: over-current, over-voltage, under-voltage, over-temperature, phase-failure, overload, etc.
12) Equipped with jump frequency control which prevents mechanical resonance and makes the system more stable and reliable;
13) Equipped with sleep-wake delay installation capability;
14) Equipped with over-torque detection;
15) Variety of maximum frequency setting source options;
16) Equipped with a bidirectional shift key , which enables users to use the shift key to view real-time parameters;
17) Rotation speed tracking re-start function: allowing rotating machinery to be started smoothly and without any shocks;
18) Equipped with automatic voltage adjustment function, which can effectively resolve problems with high-power motors low-frequency vibrations;
19) Equipped with vibration suppression;
