Multitest ecoAmp high-power contactor

The ecoAmp high-power Kelvin contactor is a solution for high-power applications of 1000+ amperes. All typical packages and modules for power applications are covered by the ecoAmp, including MOSFETs, drivers, IGBTs, power modules and power packages such as TO, SO and DIP.

To achieve equal current symmetry over I/Os within the contactor, the contacting resistance is held low and stable. Resistance stability is influenced by the contact spring itself and the condition of the device pin. The contactor is designed for an electrical performance of 500+ amperes with an inductance of 1.0 nH and below for 0.5 mm pitch.

The high-power contactor allows for testing at the full temperature range from -60 to 175°C, which is a standard requirement for automotive applications. The ecoAmp is able to stand the high thermal stress and support temperature stability during test. Thermal energy dissipation requires thermal management within the contactor.
