3-phase driveOEM motor drives often must meet demanding specifications. Invention House 3-Phase variable frequency drives (3PD) are designed to survive ambient temperature range from -45 to +55c and withstand 40g shock and 2g rms vibration. Drive control is facilitated through standard terminals or Modbus.

3PD Input/Output Configuration: Single or 3 phase input, 3 phase output.

Our 3-phase VFD is available with a flange for bulkhead mounting.

Cooling requirement is minimal - just 5 cfm across the heat sink fins.
