A Klampit will place a short across the Smart Drive PMA if the voltage ever exceeds 120 or 240 VDC.
It only shorts the PMA and not the input capacitors of the MPPT regulator (reverse flow is diode blocked).
This device can be used to protect 150 and 250V MPPT regulators from over voltage damage when deployed on hydro and wind turbines. The device will reset once the PMA rotation is stopped. It must be mounted on a suitable large heat sink.
