LFC100 Series Linear AC Power Source

Products Information:

The LFC Series Linear AC Power Source is integrated with the linear amplification circuit to ensure low noise and high stability. Users can easily develop programs to facilitate different applications. This linear power source provides clean power with THD less than 0.3% at 50/60Hz and it delivers wide output voltage range single phase 0-300V (opt.0-600V) ,3 phase 0-520V; frequency setting range 45-500Hz adjustable, fixed 50/60Hz.

Remote voltage feedback function to ensure the test voltage is consistent with the setting value.
Inrush current up to 5 times(3 times at 3 phase) of the peak current, allowing users to activate high inrush current loads(i.e. motor, compressor and so on).
Able to display the phase voltage per phase independently.
Real-time adjustment for the voltage& frequency instantly to save the time needed for the test.
Shortcut key lock, preventing the data from being modified due to any disoperation.
Either front panel or a remote RS-232 /485 control are available.
Precision True-RMS meter of volts, amps and power or power factor for displays and reports.
STEP and RAMP function: ideal for voltage and frequency variation tests and effectively reduces the inrush current during motor startup.
