9 Features: E-clamp with 24 V DC drive 24 V DC voltage is already used by automotive plants for control and sensing technology Low voltage Safe operator protection! Broad and cost-effective range of very compact motors of different manufacturers on the market Only the energy that is actually needed is consumed. Maintanance of voltage is not required during standstill. Energy consumption is subject to loads. More energy can be saved by optimising the weight of the clamping point Additional 24 V net required Solution: TUNKERS supply module (TVM) for up to 16 clamps With central voltage supply and long cable lengths, large cross sections are required Solution: Decentralized voltage supply by TVM and cascaded control of the clamps by the Tünkers motor island (TMI) 2018 TÜNKERS Maschinenbau GmbH 9

10 Power consumption of an electric clamp (here EK 50.1) I Power consumption max. 13A High momentary power consumption during start-up High power consumption during closing / clamping Averaged 6A Start-up peak Clamping operation t 10

11 Motor terminal Manager of power consumption A. Theoretical overlap of power consumption, e.g. when 5 clamps are purely operated in parallel B. Cycle cascading through intelligent clamp control via motor terminal 500 % % 100 % % High net/ transformer output 5-fold power consumption in total! Low net/ transformer output 1.5-fold power consumption in total 11
