malarz Posted October 15, 2016 Share Posted October 15, 2016 Hi everyone, Just a little question regarding the LPS-1. Are there some noteworthy differences between the HYDRA ZPM Power Supply (apparently the same technology, 2 x 310 Farad, 5V/1A) Hydra ZPM | Audiobyte and the LPS-1 Thanks in advance and have a nice day.

malarz Posted October 17, 2016 Share Posted October 17, 2016 My understanding is that the Hydra ZPM uses supercapacitors just for additional filter capacitance and the AC charging them remains connected at all times. In contrast, our UltraCap LPS-1 completely separates the AC mains from the output by alternately charging two strings of supercaps, and thus is more like a battery supply (but more convenient and with lower output impedance over a wide bandwidth). The LPS-1 is a vastly more complicated design (262 parts on the board plus a lot of software code), and this was all done in service of the design goal of complete blockage of leakage currents. To-date the only other firm that has accomplished a bank-switching, processor-controlled, supercapacitor-based linear power supply is Vinne Rossi--currently as the built-in supply for his very fine LIO modular source/amp component, though I understand he has announced plans for a $1,000 stand-alone 2.5 amp PS. I hope that helps a little. Supercapacitors are amazing high-energy-density devices, but utilizing them as isolated power sources is not a trivial task. Thanks a lot for for your explanations.
