Battery Status Meter (TM500A)
The TM500A features six data monitoring functions and three indicators
including:
• State-of-charge/amp-hour content (full or percent of capacity)
• State-of-charge/voltage (real-time voltage level, historical high and
low system voltage)
• Amps (real-time amps, total charging amps, total load amps)
• Amp hours removed
• Days since fully charged
• Cumulative amp hours
• Recharge indicator
• Low-voltage indicator
• Full-charge indicator
The unit is configurable for specific system or application functions such
as setting the CHARGED indication parameters, battery capacity,
charging efficiency, low-battery warning conditions and a recharge
reminder. The TM500A can monitor any battery supply from
approximately 8 to 65 volts, track energy consumption, and estimate
remaining battery life.
The TM500A operates on 12-, 24-, or 48-volt battery systems (48-volt
systems require an optional shunt board).
