Siemens 6SE6420-2UD17-5AA1 Inverter Drive Module

Siemens 6SE6420-2UD17-5AA1 Micromaster 420 Inverter Drive Module is a compact, three‑phase variable frequency drive designed for precise speed control of small motors in industrial automation. Rated at 0.75 kW, it accepts 380–480 VAC three‑phase mains (nominal 400 V) and delivers an output up to 480 VAC with a speed range from 0 to 550 Hz. The drive uses a linear V/f control (FCC, V/f) for smooth torque across the speed range and offers a typical power factor of around 0.95 with about 96% efficiency. An IP20 enclosure rating protects the electronics in indoor control cabinets, while an operating ambient range of −10 to +50 °C keeps it usable in typical factory environments. Its height is approximately 0.173 m, and it is part of Siemens’ Micromaster 420 family, known for straightforward configuration and integration into standard drive systems. The 6SE6420-2UD17-5AA1 is a suitable choice when a compact, economical solution is needed to accurately regulate speed of a small three‑phase motor on 400 V power networks.
