What does this Active Line Module do in a drive system?
This unit is designed to feed power into a SINAMICS drive system and manage the DC link efficiently. It is also suitable for regenerative operation, allowing energy to be fed back when the application conditions permit.
What are the main electrical ratings of this module?
The module is rated at 16 kW in standard duty, 21 kW in S6 duty and up to 35 kW maximum. Its DC-link current is 27 A at 600 V DC, rising to 35 A in S6 duty and 59 A maximum.
What input supply does it require?
It is intended for a three-phase AC supply with a line voltage range of 342 to 528 V and a line frequency of 47 to 63 Hz.
Is it suitable for regenerative applications?
Yes. The module has a regenerative feedback power rating of 16 kW, 21 kW in S6 duty and 35 kW maximum, making it suitable for applications where energy can be returned to the supply.
What DC link voltage values are used?
Factory settings are 600 V DC for 380 to 400 V AC input and 625 V DC for 400 to 415 V AC input. In Smart Mode, the DC-link voltage is maintained at 1.35 times the line voltage.
How does the module behave in Active Mode and Smart Mode?
In Active Mode, the module operates with a fundamental power factor of 1 and total power factor of 1. In Smart Mode, the minimum fundamental power factor is 0.96, with a total power factor range of 0.65 to 0.90.
What are the line-side connection details?
The line side uses screw-type terminals at X1. Supported conductor cross-sections are 2.50 to 10.00 mm², with an M5 PE connection. The shield connection is integrated into the connection plug.
What are the physical dimensions and construction style?
This module has a Booksize construction and measures 100 mm wide, 380 mm high and 226 mm deep. Its net weight is 8.8 kg. For reference, these figures apply to Siemens 6SL3131-7TE21-6AA3.
What enclosure rating does it have?
The unit is rated IP20 and listed as UL open type, so it is intended for installation inside a suitable electrical enclosure rather than for exposed mounting.
What operating conditions should be considered?
The specified ambient operating temperature is 0 to 40 °C, with an installation altitude of up to 1,000 m. The module uses external air cooling with a cooling air throughput of 0.016 m³/s.
What is the noise level and power loss during operation?
The sound pressure level is specified at 60 dB, and power loss is 0.29 kW at rated power, including losses from the 24 V DC electronics supply.
Are there cable length limits to consider?
Yes. Maximum line length is 630 m for shielded cable and 850 m for unshielded cable. In the stated configuration with Active Interface Module and Basic Line Filter, the RI suppression classification reaches Category C3 according to EN 61800-3, and Category C2 can be achieved with a line filter for total cable lengths up to 350 m.
