Buy for Today. Plan for Tomorrow. In addition to being a low cost 60 Hz sine wave filter, FlexSine®120 Hz sine wave filters can operate at fundamental frequencies up to 120 Hz without de-rating (Contact CTM for operating unit above 120 Hz). Motor advances are driving the market to switch to faster spinning PM motors. These higher speeds lead to high frequency harmonic distortion at the output of the drive. Consequently, our competitors’ filters overheat under this additional stress, forcing them to derate their filters. Furthermore, competitors often demand higher drive switching frequencies (to decrease THID), which then requires a drive derating.
However, there is another option. Due to a unique patented design and proprietary materials, FlexSine 120 Hz sine wave filters allow you to operate at 2.5 kHz (and up to 5 kHz) therefore avoiding any drive or filter derate. By installing a CTM FlexSine 120 filter now, you not only get the benefits of a low cost 60 Hz sine wave filter, you also unlock the ability to upgrade to a 120 Hz PM motor at no additional cost, whether that is an initial or future plan. Buy for today, prepare for tomorrow.
With patented liquid cooled technology, CTM sine wave filters offer the highest power density solutions available to the market. With a CTM liquid cooled product, 97% of the product’s heat is captured by the coolant and removed from the cabinet, protecting any heat sensitive electronics. Due to superior materials and geometric shapes, magnetostriction-induced noise is significantly lower in CTM filters. CTM products are quieter, “stealthier”, solutions for applications where noise is an important factor.
For unique applications, CTM provides semi and fully custom solutions. The CTM engineering team will work with you to design a product that meets even the most challenging application requirements. Due to our design software, CTM is able to produce custom designs in as little as two business days. If you have any questions or need help finding a product give us a call today or submit a form through our contact us page.
CTM is the leading choice in power quality products because of our unparalleled capabilities. CTM offers the highest filtering capabilities, smallest package size, lowest noise, highest power density, no common mode noise, and competitive prices. Contact CTM today.
