The Wayne Kerr 1100 Overload Protection Unit is designed for use with the 6430B or 6440B Component Analyzers, providing a solution that protects test equipment from charged capacitors. In such an event, the protection unit blows fuses, which can be easily and cheaply replaced, whilst the test equipment remains unharmed and continues to provide reliable accurate performance. The protection unit will protect the test equipment from up to 25 Joules of charged energy.
