Active Line Module — what it does in the drive system
The 6SL3136-7TE28-0AA3: This is the regenerative front end for a multi-axis S120 drive group — it supplies the DC link that Motor Modules draw from, and it actively shapes the input current to keep line-side harmonics low without a separate 12-pulse transformer.
Booksize frame and cold-plate cooling — panel fit
This module uses the Booksize mechanical format, which means it mounts side-by-side in a cabinet with other S120 Booksize units, sharing a common DC bus and DRIVE-CLiQ ring. Cooling is via cold plate — the module clamps to a liquid-cooled backplate or a finned heatsink that ducts heat out of the enclosure, so the panel interior stays cooler than with fan-cooled units. That matters when you are packing multiple drives into a sealed cabinet in a pulp mill or a marine engine room.
Product class C — what that means for your order
Siemens classifies this as product class C: manufactured or produced to order, not a stocked shelf item. That means the module is built against a confirmed order, so lead time is driven by the production queue rather than warehouse availability. For a BOM freeze or a line-down replacement, you want to get the RFQ in early — the factory schedule sets the ship date, not a distributor bin.
Compliance and documentation — RoHS, REACH, export
RoHS compliant since 20 August 2015. REACH Article 33 declares lead (CAS 7439-92-1) above 0.1% w/w in one or more homogeneous materials — the supplier must pass that declaration down the chain if requested. Export control is AL:N / ECCN:N, so no license barrier for standard industrial shipments.
