DETAILED DESCRIPTION

VFPS1…

Α compact drive series with three-phase supply input from 18,50 KW to 630,00 KW motors that combining the most advanced and optimized mode for energy saving with a compact and complete line as well as a function software dedicated to pump and fan applications.
The built-in EMC filters and the DC reactors supplied with the drive allow to significantly reduce the generated harmonic distortions and to limit the input current to a maximum value of 1.1 times the output current.
The VFPS1 has a QUICK mode that provides a customized menu of 32 specific parameters for a single application, inhibiting access to all the other parameters..
