The PSC-300S Power Supply Charger from Midtronics provide clean, reliable power for charging and maintaining battery state-of-charge during service reflash and complex maintenance. When operating as a power supply, the PSC converts 120V AC line input into a virtually noise-free, nominal 13.6V DC output. When operating as a battery charger, the PSC delivers current up to the rated value for charging any 12V lead-acid battery in which voltage is depressed due to a discharge event. PSC senses when the battery is fully charged, and tapers current to operate as a regulated power supply to sustain any accessory loads or offset any parasitic drain.
