Product Description:

The SV3425-01000 is an AC flux vector drive manufactured by Kollmorgen and included in the SV3000 Flux Vector Drives series. Its primary role in industrial automation is to modulate voltage and frequency so a three-phase induction motor can deliver closed-loop torque and speed control for conveyors, mixers, and similar continuous-duty loads. External dynamic-braking hardware can be connected to the factory-provided terminals so deceleration energy is shunted through an external resistor instead of feeding back to the line.

The drive is rated for 25 HP on a 460 VAC supply. Rated output current is 34.0 A RMS, which is the continuous current the inverter can supply without exceeding thermal limits. A base frequency of 60 Hz matches standard North American power systems and supports common motor setups. The housing has a NEMA 12 rating, so the enclosure helps keep out dust, oil, and non-corrosive fluids in general factory areas. The power section releases 615 W of heat, which must be removed by the drive's fan system. Rated input line current is 32.4 A, and the converter loads the supply at a level compatible with common 40 A branch circuits. A 4-pole, 1800 rpm TEBC motor is the intended match, and the 27.1 kVA output rating gives the apparent power available under full load.

When a rapid speed change occurs, the inverter can momentarily deliver 51.0 A RMS, giving the control system extra torque for acceleration or impact loads. This short-term current headroom helps the drive respond to load changes during starts and commanded speed transitions. Electrical efficiency is supported by an input power factor of 0.92, which keeps reactive current low. The mechanical interface follows the 284TC frame, so shaft height, bolt circle, and foot dimensions align with standard C-face motors and gearboxes used on production machinery.
