Introducing AC Master Series
In the railway sector, electric motors are widely used in various applications, such as compressors, fans and pumps. These devices require electrical energy to operate and deliver the necessary speed to the equipment they drive. By using VFDs (variable frequency drives), we can ensure that the AC motors run at the right speed according to the specific demands. This not only saves energy but also reduces maintenance costs and noise emissions.
Premium PSU’s engineering team has been working on a standardised solution to meet the increasing demand for AC/AC VFDs in trains. In a significant stride towards modernising railway systems, Premium PSU, a leading innovator in power electronics, proudly unveils its latest breakthrough product – the AC/AC Railway Variable Frequency Drive.
The new AC Master Series, comprising the TDX-3300, TDS-3300 and VDX-10K, represents a remarkable advancement in power electronics technology, offering unparalleled control and efficiency in powering railway systems. While these devices share similarities, their distinctive capabilities set them apart, delivering cutting-edge solutions for diverse railway applications and ensuring reliable and efficient power delivery in the most demanding environments.
The TDX-3300 stands as a true marvel of engineering, boasting an additional converter stage – the stepup converter. This ground-breaking feature ensures exceptional stability in power output, even amidst fluctuations in the input voltage. By elevating the input voltage, the step-up converter guarantees a consistent and independent output voltage, safeguarding critical railway equipment from power loss.
In addition, the team also developed a 400–480VAC 3-Phase / 230VAC 1-Phase model, the TDS-3300, that provides a stable voltage to the sockets of passenger cars and locomotives, as well as being able to change the frequency, e.g. to 60Hz, when required.
