Midtronics PSC Power Supply/Battery Chargers are designed to provide clean and reliable power for charging and maintaining battery state-of-charge during service reflash, complex maintenance and in the showroom. PSC Series Power Supply/Battery Chargers keep the battery fresh throughout vehicle demonstrations, which can make significant demands on the battery. In power supply mode, the PSC converts 120V AC line input into a virtually noise-free, nominal 13.4V DC output. In battery charger mode, the PSC delivers current up to the rated value for charging any voltage-depressed 12V lead-acid battery. Once the battery is fully charged, the PSC converts a 120 VAC line input into a virtually “noise free” 13.6 VDC output.
