Eaton DG1 Variable Frequency Drive 20 HP

The Eaton DG1 variable frequency drive delivers 20 hp maximum output power and 31 A maximum output current for three-phase AC motor control. It accepts 380 to 500 VAC input voltage at 50 or 60 Hz and provides 0 to 400 Hz output frequency range. The NEMA 1 enclosure suits indoor industrial environments.

Input Voltage and Phase Constraints

This drive requires a three-phase AC supply between 380 and 500 VAC at 50 or 60 Hz for proper operation. Single-phase input is not supported by the DG1-34031FB-C21C model. The output mirrors the input voltage at 480 VAC three-phase with adjustable frequency up to 400 Hz. Ensure your facility power matches these exact electrical specifications.

Installation Compatibility Checks

Verify that your motor is rated for three-phase 480 VAC operation and does not exceed 20 hp or 31 A full-load current. Confirm the NEMA 1 enclosure meets your environmental protection requirements for the installation location. Check that available panel space and wiring infrastructure accommodate the drive's connection terminals and cooling needs.

Questions about this item

Should I choose the 20 HP or a different capacity for my 31 A motor?

This drive is rated for 20 HP and 31 A output, matching motors that draw up to 31 amps at 480 V AC three-phase.

What does the 0 to 400 Hz output frequency range mean when the drive is running?

The motor speed can be varied continuously from standstill up to 400 Hz, allowing operation above the standard 50 or 60 Hz line frequency.

How does the three-phase 380 to 500 V AC input affect installation?

The unit requires a three-phase supply between 380 and 500 V AC at 50 or 60 Hz and delivers three-phase 480 V AC output.
