Hifisonix Improved Soft Start + DC Blocker PCB aka iSSDCB
in Power amplifiers, Power supplies
The Improved SS + DCB aka iSSDCB provides mains in-rush current limiting to 10A and blocks any DC on the mains making this a welcome upgrade for any power amplifier. The maximum continuous AC mains load current that the board supports is 4.6A RMS. On 240VAC mains supply this translates to a continuous load of […]
