AXA's 28 VDC unit is available also with 400 Hz input voltage.
The Add on Module can be supplied by almost any existing 400 Hz power unit and is therefore available in both fixed and mobile stand alone versions.
Further, the Add on Mocule can be supplied mounted from the factory on new AXA 2200 400 Hz converters (pls. refer to combi units) or it can be retrofitted on existing converters.
