System function and position

Rebuilt from individual evidence

Radwell identifies EVF8104-A as a Lenze drive and inverter.

The EVF8104-A listing specifies a 4 A drive for 220/240 VAC.

The unit sits in a cabinet between the AC supply and a controlled motor, where its inverter stage regulates motor power.

Unknown: installation-specific compatibility, replacement fit, and current commercial availability require separate confirmation for EVF8104-A.

System role

This section explains what the product does and where it acts in the surrounding system.

Function: Converts the AC supply into controlled motor power for variable-speed operation.
System position: Sits in the cabinet power path between the incoming AC supply and the motor.
Upstream / inputs: Receives 220/240 VAC input and control setpoints.
Downstream / outputs: Supplies regulated electrical output to the connected motor.
Limitations: Unknown: installation-specific compatibility, replacement fit, and current commercial availability require separate confirmation for EVF8104-A.
