Tecpro

Tecpro는 '두개의 와이어' 혹은, 많은 사람들이 같은 통신에 참여할 수 있게 해주는 '파티라인', '링' 시스템이라고 알려져 있습니다. 모든 사용자는 전화기 시스템처럼 일제히 말할 수 있는 동시에 같은 서킷에서 다른 사용자들의 말을 들을 수 있는 전방향의 대화가 가능하도록 합니다. Tecpro 시스템의 주요 어플리케이션은 극장, 컨퍼런스, 라이브 공연 그리고 방송 시스팀에서 사용됩니다.

PB752

The Tecpro Series 2 PB752 Power Booster provides a simple method of supplementing the 24V DC system power within existing Intercom systems of any size when there is insufficient drive current available. This may be due to power loss over long cable runs or because too many outstations and loudspeaker stations are connected to the system.

To avoid altering the system impedance set by the main power supply, the PB752 does not terminate the line and no additional isolating components are required.

Maximum available current is 2A and is shared between two outputs to facilitate connection to larger two circuit intercom systems. When connected to a single circuit only, the full 2A is available for that circuit.

The PB752 can be linked to an intercom system at any point. If cable runs are long, the farthest point where voltage drop off is worst would typically be the best connection point.

The Power Booster is protected against short circuit and over-temperature. Protection is electronic and automatic and no resetting is necessary following removal of a fault condition. The unit can be operated world-wide without the need to change AC power supply settings.

The Power Booster is compatible with older Tecpro designs.
