Expansion cards
If the extended function (RS485 card, PG card, Canbus card, etc.) for other functional modules is
needed, please specify the functional module card you want when ordering.

Brake unit and brake resistor
ST500 converter 220V 11kW and below, 380V 22kW and below have a built-in brake unit.
Please refer to the user purchase table to match the braking resistance can; 220V 15kW and above as
well as 380V 30kW and above models need to use an external brake unit, if there is a need to brake,
please use the Sourcetronic brake unit and select a braking resistor resistance value and power
according to the specific situation.
