Adjustable Battery / Hour Meter
Multi-volts with 8 pin connector
R8867A Series
Panel cutout: Round Φ52mm
Compact structure, high reliability & durability
Battery Meter Features
- Tri-color 10-bar LED displays state of discharge (7 green, 2 yellow, 1 red LEDs)
- Only when battery is properly charged and keeps at the high voltage (HVR) over 6 minutes, is the right most LED lighted.
- As battery’s state-of-charge decreases, successive LED lights up, one at a time, 160s after detecting state low voltage.
- 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.
- 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.
