Series Launch for Frequency Converter SD4S

In the course of the year 2022, the new SD4S series by SIEB & MEYER AG will grow to a total of nine sizes, which cover and even extent the current power range of the SD2S series. The functionally tested successor products for the SD2S series provide numerous advantages for customers.
 

At the beginning of 2022, SD4S will be available in five construction sizes in the 230 V class; over the first half of the year, four additional construction sizes in the 400 V class will be launched. Together these frequency converters cover the current power range (1.4...55 kVA) of the SD2S series and even extend it downwards and upwards (0.8...66 kVA). "We look forward to the extensive series launch of SD4S," said Torsten Blankenburg, CTO at SIEB & MEYER AG. "Then, even more customers will benefit from the key advantages of the SD4x product family: optimized performance, higher speeds and low motor heating without additional sine-wave filter."

Until recently, the focus was still on field testing of the new SD4x development platform. The first SD4S device variant was developed foremost to close a gap in the existing product line of frequency converters regarding the lower power ranges: It is a switch cabinet variant of SD4S with 800 W / 1.6 kVA. At the end of the second quarter of 2021, another construction size with 1,600 W / 3.2 kVA was available. These SD4S variants make an optimal basis for the operation of high-speed spindles and motors in the power range from a few hundred watts up to 1.6 kW. Both device variants are already working successfully in customer installations. Testing in different applications proves that SIEB & MEYER has developed a stable system for universal use.
