Boost Talk Battery and Loop Current to Line Powered Devices

Talk Battery Booster

The TBB-1B will boost talk battery voltage up to 40 VDC and loop current up to 26mA on single analog line extensions behind PABX�s and electronic key systems. This is helpful for powering line powered devices such as Touch Tone dialers and emergency phones on low voltage and/or low loop current extensions. When the TBB-1A is being used, the POWER LED lights extra bright to show activity. The TBB-1B is not compatible with Pulse/Rotary dialing.
