Bypass Solutions for Critical Applications
We understand the criticality of your application and your quest for an uninterrupted process. The most reliable products can also fail at times, but Amtech will never let you down. Amtech solution lets the system run on the bypass system till the process gets completed while repair of module can be carried out at a convenient time later.
Our series of Bypass Solutions from 2/3/5 contactor bypass, soft starter bypass or hot standby (redundant system) lets your system continue to work without any production loss.
At times, your process needs bump-less transfer in no time without any major change in speed. We have the solutions for every challenge. Our system solutions equipped with state-of-the-art technology, monitors the health of the VFD all the time and in an abnormal situation, transfers the control to the hot standby VFD in no time. The transfer will be so smooth at times, that even your control room will not be able to diagnose the transfer. Successfully implemented many such solutions on critical applications in various power plants.
Low Harmonic Solutions
With the increased usage of Power Electronics products and Variable Frequency Drives (VFDs), there is concern for a potential increase in the level of harmonic distortion conducted back into the utility power lines. The new harmonic guidelines of IEEE will force the user to restrict the harmonic level.
Our VFDs come with Low Harmonic Solutions customized to your need. They come either with ACL (line reactor) or DCL (DC reactor), which reduces the harmonic level to 35...45%.
Our multi-pulse converter system offers huge reduction in harmonic current and voltage distortion for various systems and locations to 8...12% and meet the reasonable limits of IEEE 519.
More so, for the stringent requirements demanding harmonic current distortion less 5%, Amtech offers Active Front-end Converters (AFC) or Wideband Harmonic Filter (WHF). Both Axpert-i-Sine Series AFC and WHF are capable of reducing the harmonic content to below 5% at rated load. Apart from that AFC can also be used to feed the regenerative energy back into the grid.
We also offer Active Harmonic Filter (AHF) for the harmonic mitigation at a system level.
