In power supply mode, the PSC converts 120 volt AC line input into a virtually noise-free, nominal 13.4 volt DC output. In battery charger mode, the PSC delivers current up to the rated value for charging any voltage-depressed 12 volt lead-acid battery. Once fully charged, the PSC detects battery condition and tapers current output to to sustain accessory loads or offset any parasitic drain.
PSC Series power supply chargers are available in 15A, 30A, and 55A configurations.

 Features:

• Allows for vehicles to be displayed with all electrical features and accessories activated
• Great for maintaining the battery while powering aftermarket accessories that drive sales
• Provides a constant clean power supply for using scan tools and reprogramming of ECMs without discharging battery
• Advanced switch-mode design - Provides a cleaner, more reliable power source than using a standard charge; Fully-regulated DC output prevents overcharging of the battery and provides precise control to maintain the necessary battery voltage during complex service and reflash; Quiet, small, and compact for portability
• Commercial design and heavy-duty internal components ensure years of continuous use
• Multiple protection features for a long, trouble-free life - Reverse battery polarity protection via replaceable fuses; Brownout input protection; Over-current protection; cycle-by-cycle peak limiting and rated current-limiting to maximize the life of the converter; Over-temperature protection
• Unique proportional fan control circuit - Sets the fan speed directly proportional to the converters internal ambient temperature, enables the fan to turn on and off very slowly, minimizing unwanted fan-starting noise
• High quality, detachable cables for easy field service
• Optional protective carrying case for storage or during use
