Baumüller BUS6-VC-AC-0020 Bus621-10 15-54 (8.3.3)

Baumüller BUS6-VC-AC-0020 Bus621-10 15-54 (8.3.3) is a BUS621 power unit designed for use with Baumüller’s BUS6-VC drive system to power and regulate AC servo motors. This power unit is part of the BUS6-VC Regler family and is compatible with the BUS621 power-regulator variants, including the CE+UL-rated manuals that cover the BUS621, 622, 623 and 624 series. The BUS621 family supports two PWM frequency configurations (8 kHz and 4 kHz), with nominal and peak current ratings that vary by version, ranging from a few amperes up to tens of amperes and up to about 75 A for higher‑current variants. For example, the 8 kHz/4 kHz operating modes provide different nominal and peak currents across versions (e.g., lower-current variants around 5–12 A nominal with modest peak, while higher‑current variants reach well into the tens of amperes).
