Numerous applications require lower than standard line voltages for a bushless servo application. The AKD can be ordered in a low voltage variant that allows for operation as low as 48 Volts DC. The part number for this variant is AKD-P00306-NBAN-0069 and has some special characteristics on the power scripts to allow for this operation.

The DC bus voltage must at least reach 20VDC so as to not generate an under-voltage fault.
If applying DC power to the AC mains input terminals (L1 and L2), The DC bus voltage must at least reach 30VDC so that the in-rush relay will switch on.
