6SL3224-0BE33-7UA0 Siemens SINAMICS G120 PM240 Power Module Unfiltered 380-480V 3AC 37kW

1.Overview of the 6SL3224-0BE33-7UA0 Siemens

The Siemens 6SL3224-0BE33-7UA0 PM240 Power Module, part of the SINAMICS G120 series, is designed for variable-frequency speed control of three-phase AC motors with a capacity of 37 kW (heavy duty) or 45 kW (light duty). The module features a wide 3AC input voltage range of 380–480 V and a built-in brake chopper, enabling rapid deceleration and four-quadrant operation without an external braking unit. It also offers a high overload capacity of 200% for 3 seconds and 150% for 60 seconds, easily handling shock loads and rapid acceleration and deceleration.

The compact IP20 metal housing measures only 497 × 275 × 204 mm and supports DIN rail or backplane mounting. It boasts a 30% increase in power density over the previous generation. Built-in low-inductance busbars and nano-film capacitors reduce dv/dt by 40%, extending motor insulation life. The module's plug-and-play control unit, the CU240B/E-2, supports vector, servo, and V/f modes, with a speed accuracy of ±0.01% and a torque dynamic response of < 5 ms, making it suitable for high-dynamic applications such as high-speed filling, handling, and winding.

Integrated RS485, PROFIBUS-DP, PROFINET, and Ethernet interfaces enable commissioning, monitoring, and remote diagnostics for the inverter, PLC, and host computer via a single network cable. Built-in STO (Safe Torque Off) and SS1 (Safe Stop 1) functions achieve SIL3/PLe standards without the need for external safety relays, reducing safety costs. The high-efficiency cooling fan activates only when the heatsink temperature exceeds 40°C, generating less than 55 dB of operating noise, ensuring quiet operation even during nighttime production. The pluggable fan, capacitor, and terminals reduce maintenance time by 70%, resulting in an MTBF of up to 120,000 hours. The 6SL3224-0BE33-7UA0 has been widely used in OEM and project-based markets such as food and beverage, textile and chemical fiber, logistics sorting, fans and pumps, and machine tool spindles. It is an energy-saving, compact, and reliable drive core in the Industry 4.0 era.
