TECPRO BA905 Power supply boost adapter


The BA905 is used to add an additional power supply to a Tecpro system. It isolates the additional power supply from the communications line, carrying only the DC power through to the circuit (without this adaptor, the additional power supply would provide a second communications line termination, which would cause problems). Any Tecpro MS or PS unit can be used to boost the power in a circuit by connecting the BA905 in series between the circuit outlet on the MS or PS unit and the circuit to be boosted. The BA905 also will allow any 24-30 volt power supply to be used as a booster, but will probably require the addition of a diode in series with the power supply.

Typical applications include providing power to a remote set of outstations, minimising line losses, or in systems with a large number of loudspeaking outstations.
