Inrush Current Damping Modules

Inductors (e.g. transformers) exhibit an extremely high initial surge current (up to 100 x rated current) at switch-on depending on phase angle and magnetic forming. This causes problems with the protection of such circuits since normal fuses are triggered by these high values. A low-cost solution to this problem is provided by our series MCD damping modules. These limit the inrush current surge to a value at which selective protection is possible. For the duration of the high inrush current an ohmic resistor attenuates the current surge and is subsequently by-passed by a relay contact.
