Product Description:

The SV3402-01000 is a flux vector AC drive built by Kollmorgen for the SV3000 Flux Vector Drives series. It converts fixed three-phase utility power into a variable-frequency, variable-voltage output so induction motors can meet commanded speed and torque references in automated conveyors, mixers, and process equipment. Closed-loop current sensing and fast digital signal processing allow the unit to hold motor performance when loads fluctuate. Its real-time vector control supports low-speed operation without an encoder, simplifying installation in both retrofits and new machinery. This control method also allows standard induction motors to cover a wider operating range without adding separate feedback hardware.

The inverter delivers 2 HP of mechanical power while supplying 3.4 A RMS to the motor windings, a level it can sustain continuously through its thermal design. Its apparent power rating is 2.7 kVA, matching branch-circuit capacities in typical 230-volt cabinets. An input displacement factor of 0.95 keeps reactive demand low and helps reduce unnecessary line loading. For rapid speed changes, the control loop permits 5.1 A RMS peak, providing additional torque above the steady value. Under nominal loading, the rectifier draws 4.9 A from the mains, which helps match upstream protection and conductor capacity. This combination supports stable continuous operation while still allowing brief torque increases during acceleration or changing process demand.

The drive uses a sealed NEMA 4/12 housing that resists dust and water splashes, and the internal fan moves air across the heat sink. This enclosure style is useful in areas where airborne debris or incidental liquid exposure is present. At a 6 kHz carrier frequency, the drive dissipates 75 W, heat that the fan ejects to keep semiconductor temperatures within limits. Upstream protection is furnished by a 6 A AC line fuse that opens on short-circuit faults. The braking circuit can absorb 100% of generated torque, allowing full deceleration during the 5-second portion of the 5 s/2 min duty cycle. This braking behavior supports frequent stopping and restarting on loads that need controlled speed reduction.
