CommBat Talk Battery
The CommBat talk battery is a unique power source for talk battery circuits. The CommBat provides a constant current of 10mA for the talk line. The helps ensure the talk circuit is loud and clear, even on longer loops.
As the line becomes longer, CommBat increases the battery voltage up to 30VDC, if necessary, to maintain talk current on the line.
The CommBat is powered by four AA batteries for easy replacement and small size.
