SD4x series grows

Only recently SIEB & MEYER has launched a new SD2M construction size with a higher output power and output current of 470 kVA / 800 Arms (at 400 V) that allows for powerful system solutions in the sector of turbo blowers and turbo compressors. "This device comes with state-of-the-art power electronics," said Torsten Blankenburg, CTO at SIEB & MEYER AG. "We have prepared everything so that this device can be transferred as a new logic variant into SD4M. This makes the changeover feasible relatively quickly."

Customers mainly benefit from the improvements to the control loop and the Ethernet-based bus systems. The new 32-bit processor is up to five times faster and therefore allows a higher resolution and more precise calculations. With the multiprotocol chip, which is used for the globally established Ethernet-based interfaces, as well as useful additional functions like a real time clock, the SD4x devices are well prepared for the future. Existing customers can of course continue to use SD2M – for new projects, though, switching to SD4M is quite easy: There is not much to be adapted on the power side. On the logic side, customers only need to use a slightly different connector and consider a few minor differences.
