Abstract

본 발명은 무선 PBX 시스템에 연결된 단말기 측으로 전원을 공급하는 무선 PBX 시스템의 전원공급장치에 관한 것으로, 일정한 전원을 단말기 측에 공급하고 선로상태 및 과전류 상태를 감지하여 적절한 조치를 취해줄수 있는 무선 PBX 시스템의 전원 공급 장치 및 그것의 제어방법에 관한 것이다.The present invention relates to a power supply device of a wireless PBX system for supplying power to a terminal side connected to a wireless PBX system. The present invention relates to a wireless PBX system capable of supplying constant power to a terminal side and detecting appropriate line conditions and overcurrent conditions. It relates to a power supply device and a control method thereof.

본 발명은 무선 PBX의 시스템 본체에 연결된 단말기 측으로 일정 전류를 공급하고, 과전류 공급시에 전류공급을 차단하고, 선로 상태를 감지하여 시스템 운용자에게 이를 경보해 주므로, 과전류에 기인한 단말기의 손상을 방지할수 있고, 무선 PBX 시스템을 효과적으로 운용할 수 있다.The present invention supplies a constant current to the terminal side connected to the system main body of the wireless PBX, cut off the current supply when the overcurrent is supplied, and detects the line condition to alert the system operator, thereby preventing damage to the terminal due to overcurrent Can operate the wireless PBX system effectively.
