Whether multiple DC power supplies can be combined for higher voltage or current depends on the specific model and its output topology. Some power supplies support series connection (for higher voltage) or parallel connection (for higher current), but this requires compatible output stages and proper load balancing. Not all models are designed for stacking — connecting incompatible units can damage the supplies or create unsafe conditions. Berkeley Nucleonics offers the Heinzinger EVO Series, which is adding multi-unit stacking capability.
