Sieve & Meyer
Frequency inverter series expanded
Sieb & Meyer presents the SD4S, SD4M and SD4B, the latest models in the SD4x series of frequency inverters for high-speed applications.
The SD4B, successor to the "SD2B plus", is suitable for use as a highly dynamic servo amplifier for operating rotary and linear low-voltage servomotors as well as for operating high-speed low-voltage synchronous and asynchronous motors. In the high-speed range, the frequency inverter allows sensor-based operation of motors with a superimposed synchronization function based on 24 V synchronization signals.
This allows several high-speed motors to be operated synchronously in master/slave mode. The SD4S from Sieb & Meyer is available in numerous sizes in the 230 V class and 400 V class. Overall, these devices cover the power range (1.4 to 55 kVA) of the SD2S series or extend it upwards and downwards (0.8 to 66 kVA). The SD4M three-level inverters are suitable for turbo compressors and turbocompressors, for example.
