Midtronics PSC Power Supply Chargers provide clean, reliable power for charging and maintaining battery state-of-charge. These chargers/maintainers are designed for use during service reflashing, complex maintenance, or on the showroom floor where vehicle demonstrations can make significant demands the battery. 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.

Midtronics PSC or Power Supply Chargers are an absolute must for “re-flashing” vehicle computers. Conventional chargers and booster packs were not designed for reflash use, and can cause problems such as program interruption (need to start over, lose time!) and, worse yet, damage to vehicle electronics (costly part replacement and even more lost time!). Do it right the first time with right equipment -the PSC Charger from Midtronics!


  • Converts 120V AC line input into a virtually noise-free nominal 13.6VDC output
  • As a charger, the PSC unit delivers current up to the rated value to charge any 12V lead-acid battery as needed
  • Once battery is charged, the PSC tapers current to operate as a regulated power supply that will sustain accessory loads and offset parasitic drain
  • Reverse connection, brown-out, over-current, and over-temperature protections
  • Same platform required by Audi, Jaguar, Land-Rover, VW, and Volvo; also approved by Daimler-Chrysler, Ford, GM, and Mercedes-Benz
  • 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
  • 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
  • Quiet, small, and compact for portability
  • Commercial design and heavy-duty internal components ensure years of continuous use
  • 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
  • Maximum amps output at regulated voltage: 55 A
  • Output voltage tolerance (no load) + or - .7%
  • Output voltage (full load) approx. 13.4 V (DC)
  • Ripple and noise <50 mV rms
  • Typical efficiency >100%
  • Line regulation 100 mV rms
  • Load regulation <1%
  • Thermal protection
  • Working temperature range 0-40C
  • On/off switch with power LED indicator
  • Fuse Protection: Internal breaker
  • 3-stage charge controller
  • 6 ft Removable clamp set
