20 hp, vfd, variable frequency ac motor speed drive
380 ~ 480VAC Three Phase Input.
If you have 200 ~ 240VAC Input:
HITACHI L300P Series is a Variable Torque Drive
ideally suited for Fan, Blower or Pump Application.
If your Application involves Starting under Load Conditions
or Operating at Low Motor Speed (less than 50% rated)
you might require a Drive with
Constant Torque Characteristics.
AC or DC Variable Speed Drives
