1. Product Application:
LKW5C series automatic reactive power compensation controller is suitable for automatic reactive
power adjustment and control of balanced distribution network of low-voltage 400V system, which can
make the power factor of power grid reach a predetermined state, improve the utilization efficiency of
power transformer, reduce line loss, improve the voltage quality of power supply, reduce or eliminate the
fine of power regulation, and improve economic and social benefits.
2. Product Features:
2.1. It has two working modes (power factor control and reactive power control).
2.2. It has the function of switching oscillation locking in power factor mode.
2.3. It can automatically identify the polarity of current signal, and the identification accuracy and
reliability are extremely high.
2.4. Simple operation and friendly human-computer interaction.
2.5. With harmonic measurement and protection functions.
2.6. All digital control parameters are adjustable.
2.7. With manual and automatic operation modes, it is convenient for installation and debugging.
2.8. With overvoltage protection function.
2.9. Once the control parameters are adjusted, they will be permanently saved, and they will not be lost
after power failure.
