The Delta VFD32AMH43ANSAA is a Frame E AC drive rated for 15 kW (20 HP) motor output on a 3-phase 380–480 VAC supply. It delivers 36.0 A rated output current, with heavy-duty input current of 35.2 A and normal-duty input of 39.6 A — the HD figure tells you the continuous current it can sustain under a constant-torque load like a conveyor or extruder; the ND figure applies for variable-torque loads such as fans and pumps. Cooling is natural convection — no fan to fail, so it runs silent and suits dusty environments, but you need to respect the free-air space around Frame E for heat dissipation. IP20 means it's for clean, dry cabinet mounting only; not for washdown or outdoor placement.
The EMC filter is optional. The drive ships without an internal filter as standard.
