Product Description
High Performance General Purpose Inverter Industrial VF Control, Invt Inverter Chf100
Brief Introduction
CHF100A series high performance universal 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
Three control modes:
Without PG vector (SVC);
V/F control;
And torque control.
Starting torque: Without PG vector control: 0.5Hz/150% (SVC);
18.5kW-90kW inverter built-in DC reactor to improve input power factor and increaseoverall efficiency and stability;
Internal brake unit with every specification 0.75-15kW, so that the braking resister can be connected directlyfor a quick stop;
16-steps simple PLC, multi-speed control, and PID control;
Supporting multi-frequency installation methods: Digital setup, analog quantity setup, PID setup, and communication setup;
Supports starting and stopping DC brake;
The input and output terminals may be freely programmed, so users may combine a variety of operating modes as needed;
Equipped with jump frequency control which prevents mechanical resonance and makes the system more stable and reliable;
Equipped with instantaneous power failure non-outage capability;
Equipped with sleep-wake delay installation capability;
Equipped with over-torque detection;
Variety of maximum frequency setting source options;
Equipped with a bidirectional shift key, which enables users to use the shift key to view real-time parameters;
Rotation speed tracking re-start function: Allowing rotating machinery to be started smoothly and without any shocks;
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;
Equipped with automatic voltage adjustment function, which can effectively resolve problems with high-power motors low-frequency vibrations;
Equipped with vibration suppression;
Offering a variety of fault protection functions: Over-current, over-voltage, under-voltage, over-temperature, phase-failure, overload, etc;
Low voltage inverter.

Applications
Belt-type conveyors, hoists, winches, emulsion pumps, electric submersible pumps, mining fans, water pumps, etc.
Solution
CHF100A series inverter used on the centre air conditioner
The difference of effluent temperature and backwater temperature of the water-cycling system in the central air-conditioning indicates the heat exchanger of the whole system needed, so, we can control the low of water-cycling to control the heat exchange speed based on the difference, it is the first choice control mode for energy saving.
