Frequency setting
method
Settings can be implemented through digital, analog,
pulse frequency, multi-step speed run, simple PLC, PID,
and communication.
Settings can be combined and the setting channels can
be switched.
Automatic voltage
regulation
The output voltage can be kept constant although the
grid voltage changes.
Fault protection
Many protection functions available, such as protection
against overcurrent, overvoltage, undervoltage,
