Is applicable to any brand inverter; Capacity: 0.75-22 kw / 30 to 55 kw / 75-132 - kw. Allow parallel to use, there is no limit to the capacity; Allow for grid change big occasions to use; Has completely short circuit protection, won't because resistance short-circuit damage frequency converter; Special design, can use ordinary resistance, don't have to choose non-inductive resistance; Full voltage automatic tracking, the user does not have to adjust the voltage setting; Noise filtering all the way, does not interfere with other equipment;
Performance optimization; Braking resistor for selected items, can be made according to user needs resistance box.
