We've recently updated our IGBT rectifier technically with our engineering team's hard work.1).Control board and driving board in one box, anti corrosion. 2).Inside cable collection all in terminals, no man-made welding, more reliable. 3).Fans with filter for anti dust and corrosion, easy change. 4).Cooling channel in the middle of cabinet, and nearby transformer with one fan. 5).Breaker at input side, more safe. 6). Cabinet more compact. We will do the standard-mode bulk production to bring the benefits to customers:Lower price, higher IP and shorter lead time.
