Product Description:

The SV3420-11100 is a flux vector AC drive manufactured by Kollmorgen for the SV3000 Flux Vector Drives series. It is intended for industrial automation tasks that need accurate motor torque and speed regulation without relying on mechanical gear changes. By modulating voltage and frequency in real time, the drive maintains consistent output even when load conditions shift, which is valuable in material-handling lines, mixers, and pump assemblies that demand stable closed-loop control.

This model delivers 20 HP of mechanical output and is engineered for a nominal bus of 460 VAC. Under rated conditions, it draws 28.6 A from the line, converts that energy into 21.5 kVA of output power, and supplies 27.0 A RMS to the motor. A short-term overload margin of 150% for 60 s allows acceleration of heavy loads, while a peak phase output of 40.5 A RMS supports those transients without tripping protective logic. Maximum synthesized frequency is 120 Hz, enabling motors to run at twice their base speed if required. The input displacement factor is 0.87, so upstream power components can be sized with moderate reactive compensation. Closed-loop vector algorithms hold commanded velocity within 0.01% of base speed, maintaining process accuracy when supply or inertia changes.

An internal heat sink and fan reject 498 W of switching loss at a 6 kHz carrier, and the sealed NEMA 12 housing keeps dust and oil mist away from the electronics. DC bus protection activates at 750 VDC to power the dynamic brake and trips at 800 VDC to safeguard the IGBTs. The drive tolerates installation up to 3300 ft above sea level and continuous operation in ambient temperatures up to 40 °C without derating. When matched with proper motor insulation and cabling, it provides dependable service in factory cells and plant utility systems.
