FAQ
Q1: What is the Emerson UNI3403?
A legacy Unidrive AC drive, 22 kW / 30 HP, 400 V three-phase, high-power panel-mount inverter for general industrial use.
Q2: Can UNI2403 replace UNI3403?
No. UNI2403 is rated for 11 kW, so it is too small for a 22 kW UNI3403 application unless the load and current are reduced.
Q3: Does UNI3403 support servo or vector control?
Yes. Depending on configuration, it supports V/f, open-loop vector, RFC and servo modes.
