Product Introduction
When industrial processes demand precise motor control and energy efficiency, the Siemens 6SL3210-1PE21-8UL0 SINAMICS PM240-2 power module delivers robust performance with 97% efficiency. This Frame size FSB unit is part of the SINAMICS family, designed for three-phase AC drives in applications from conveyors to compressors. The Siemens 6SL3210-1PE21-8UL0 combines compact dimensions (100x292x165 mm) with a net weight of 3.00 kg, offering a space-saving yet powerful solution for modern automation lines.
Technical Specifications Breakdown
The Siemens 6SL3210-1PE21-8UL0 features a 3-phase input of 380–480 VAC with ±10% tolerance and line frequency 47–63 Hz. Rated current for low overload (LO) is 22.20 A input / 18.00 A output, and for high overload (HO) is 19.80 A input / 13.20 A output. Output power reaches 7.50 kW (10.00 hp) under LO and 5.50 kW (7.50 hp) under HO. The module supports both vector control (0–200 Hz output frequency) and V/f control (0–550 Hz) with a pulse frequency of 4 kHz. Overload capability is defined as 110% rated output for 57 s (LO) and 150% for 3 s, while HO offers 150% for 57 s and 200% for 3 s. Efficiency is 0.97, power factor λ 0.85, and power loss only 0.20 kW.
Application Scenarios
In automated production lines, the Siemens 6SL3210-1PE21-8UL0 excels in driving variable-speed conveyors and pumps. For HVAC systems, its high overload capacity handles fan startup reliably. In compressor applications, the power module maintains stable torque under fluctuating loads, reducing energy consumption by up to 3% compared to older drives. With an ambient temperature range of -10 to 50 °C (HO operation), it suits both conditioned and harsh factory environments.
Installation & Setup Guidance
The Siemens 6SL3210-1PE21-8UL0 uses plug-in screw terminals on both line and motor sides. Conductor cross-section ranges from 1.50 to 6.00 mm² (AWG 16–10). Shielded motor cables up to 50 m (164 ft) and unshielded up to 100 m (328 ft) are supported. The unit has IP20 protection and internal air cooling requiring 0.009 m³/s airflow. Ensure proper mounting in a clean, dust-free enclosure with adequate ventilation. Do not exceed 1000 m installation altitude without derating.
Maintenance & Reliability
This Siemens 6SL3210-1PE21-8UL0 module is designed for long service life with minimal maintenance. The internal cooling fan should be checked annually for dust buildup. Ambient conditions to monitor: relative humidity below 95% non-condensing, and temperatures within the specified range. The power loss of only 0.20 kW translates into lower heat generation, reducing stress on cooling systems and extending component life. With standards compliance (UL, cUL, CE, C-Tick, SEMI F47), it meets global reliability norms.
Selection Guide & Purchasing Advice
Before purchasing, verify that the Siemens 6SL3210-1PE21-8UL0 matches your motor's power rating (up to 7.5 kW LO) and voltage class. Confirm frame size compatibility with your SINAMICS G120 control unit. For applications requiring consistently low overload, this module delivers a cost-effective solution.
