摘要:
A selectively protected electrical system includes or operated with a powersource(1514) , a load (1512), a power driver circuit (1506) for controllablytransferring power from the power source (1514) to the load (1512), the powerdriver circuit(1506) being encapsulated in a potting material, and acontroller(1518) for enabling and disabling the power driver circuit (1506),the controller (1518) being un-encapsulated by the potting material. If acontaminant induced electrical fault occurs in the selectively protectedelectrical system, the electrical fault is more likely to occur in the un-encapsulated controller, such that the selectively protected electrical systemis disabled. The contaminant is inhibited from contacting and inducing anelectrical fault in the power driver circuit, thus providing for a controlledfailure of the selectively protected electrical system.
