The acronym TRIS NCT354 distinguishes an ultra-compact triple inverter with a single L1-L2-L3 mains input, a single braking resistor and three separate U-V-W outputs to drive three different motors each with its own specific operation.
The typical application of these inverters is the construction crane with one output used to drive the swing motor, one for the trolley motor and one for the hoist motor.
The TRIS NCT354 can drive motors for a total of 35-40 Hp (26-28 Kw) with a max of 25 Hp on the single output.
The NCT354 INVERTERS up to 20KW of power are in the SINGLE-THREE-PHASE version. If higher, they are only in the THREE-PHASE version.
