Battery Meter Features

  • Tri-color 10-bar LED displays state of charge & discharge (7 green, 2 yellow, 1 red LEDs)
  • Only 1 LED is lighted at a state. Default setting: Full state.
  • In the discharge process, the LED can only decrease to the next lower level and will not increase to a higher level. 
    • The LED (#3, yellow) is lighted, indicating “Energy reserve” (70% discharged).
    • Flashing yellow signals “energy reserve” alarm at 80% discharged.
    • Double flashing red and yellow LEDs signal “empty” alarm at 90% discharged, and relay lockout at the same time.
  • In the charge process, corresponding LED flashes. Flashing LED inceases one by one until #10 LED is lighted indicating fully charged.
  • When battery sets are swapped and new battery voltage equals to OCR, the right most LED #10 is lighted.

Hour Meter Features

  •  Records and displays up to 99.999.9 hours on LED
  • Hour meter LCD remains on as long as battery is connected.
  • Stores latest total in EEPROM nonvolatile memory, without need of external power or internal battery.
  • Accuracy of 0.01% throughout its operating temperature range.
  • Control pin connected, hour-glass icon flashes and hour meter accumulates time.
