I don't have any experience with driving in the multiplexed mode for nixies, but I think you don't need 300v for that, just lower the anode resistor then you will get higher brightness for dynamic scanning. There's a precise potentiometer on the board, you will get 100-230v output can be used for most Nixie applications, that would require some other kind of power module if you need 300V output or more, no power module can meet all application requirements ;)
