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).
