Automatic energy-saving operation
• V/F curve is automatically optimized according to load conditions to achieve energy-saving operation

Mains Dip Ride Through
• Despite the mains voltage change, the output voltage is maintained constant automatically


Automatic Current Limiting
• Apply auto current limiting during operation to avoid frequent tripping due to over-current.

Automatically Adjustable Switching Frequency
• Automatically adjust the switching frequency according to the load demand
 

Operating function

Control command channel
• Control command can be issued through operation panel, control terminals, and the serial ports; different channels are switchable

Frequency setting channel
• Digital setting, analog voltage/current setting, pulse setting and serial ports setting; different settings
methods are switchable.

Auxiliary frequency setting
• Flexible auxiliary frequency tuning and synthesis

Pulse output terminals
• 0 ~ 50kHz pulse square wave signal output, able to output set frequency, output frequency and other
programmable parameters.


Analog output terminals
• 2 analog outputs, 0 / 4 ~ 20mA or 0 / 2~ 10V are selectable, able to output set frequency, output frequency and other programmable parameters.
