DC fuses and on-load disconnectors
It is a combination of DC fuses and on-load disconnectors that can be fitted in one or two module frames. This solution leads to a limitation of the maximum inverter modules that can be fitted in the same inverter frame size.
SD7ICL - INRUSH CURRENT LIMITER
Avoid fluctuations in the grid
Inspired by the most accurate and powerful motor control applications and the extensive experience of Power Electronics in the variable speed drive market, Power Electronics has designed the kit SD7ICL which can provide a voltage ramp up on the MV Transformer by the LV side, allowing a transformer soft load, minimizing its inrush current and therefore avoiding fluctuations in the grid.
