PRO12-48M  TM  

  • Does not work on Optima, Brute Force or Lithium batteries.
  • Auto Ranging Battery Monitor - Connect to any fully charged lead acid battery system and the meter will select the proper range, for 12, 24, 36 or 48 Volt DC systems.
  • Works on all batteries as the meter can be set for one of two different discharge curves made by different battery manufacturers. Works on Exide, Trojan, Continental and Interstate, PowerTron, US Battery batteries and more. The PRO12-48M can be wired to work on newer type batteries as well as the standard type battery.
    • Curve 1 - Standard Lead Acid batteries have a discharge curve of 10.4 volts empty to 12.34 volts full (multiply by 2, 3 or 4 to get the range for 24, 36 or 48 volt systems).
    • Cruve 2 - For newer designed "hot" acid batteries with a discharge curve of  11.5 volts empty to 12.7 volts full as found on Exide and Trojan deep cycle batteries  (multiply by 2, 3 or 4 to get the range for 24, 36 or 48 volt systems).
  • Internal Relay - can be wired for Normally Open or Normally closed operation for controlling secondary devices- limited to 200 ma.
    • Relay opens or closes (depending on how you wire it) when the display shows fully discharged - flashing red #1 and yellow #2 LEDs
  • Can be used on forklifts, golf carts, solar sytems and any other battery powered equipment
  • Battery Status
    • The battery meter has 10 LEDS that will light to show the battery condition. When fully charged, only the 10th LED will light shown a green LED.
    • As the battery discharges, successively lower LEDs will light; the 9th, 8th, 7th and so on lighting only 1 LED.
    • At approximately 30% battery life, the #3 LED will light and the color is Yellow as a caution indicator.
    • At approximately 20% battery life remaining, the #2 LED will light as a Flashing Yellow.
    • When the battery discharges to approximately ~10% remaining life, the #1 LED will start FLASHING RED with the #2 LED FLASHING Yellow alternately.

It is recommended to have the battery or batteries recharged when the #3 LED lights Yellow as a safety margin to prevent dead batteries.

CAUTION: This is not a full proof device and no warranty is made that your battery/batteries is/are in good condition.
