The 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.
In addition to its status monitoring features, the unit can act as a remote
control, switching the inverter OFF or ON (only on inverters incorporating an
RC4/RC8 compatible remote control jack).
The TM500A operates on 12-, 24-, or 48-volt battery systems (48-volt
systems require an optional shunt board).
