The 4320W/1080W energy shelf is specially designed for the -48V art switching mode rectifier and advanced microprocessor technology, the
shelf is able to perform efficient AC to DC power conversion. The energy shelf is N+1 redundant design with hot swappable capability,
hence, particular easy and convenient for maintenance. The shelf is particularly suited for mobile communication base station, switch
exchanges, optical fiber communications, microwave base station and others -48V telecommunications equipment.
The shelf can be divided into four (4) major blocks: (1) AC PDU, (2) DC PDU, (3) Supervisory Unit and (4) Rectifier Module.
The AC PDU distributes AC power to the rectifiers and other portions of the shelf. AC MCB is available within the AC PDU to isolate the
shelf from the mains.
The DC PDU distributes DC power from the rectifiers to external loads and batteries. Within the DC PDU, there are MCBs to be connected to external loads. The DC PDU also incorporates battery connections which are equipped with battery MCB for protection purposes. The battery connections allow the system to have power backup capability in the event of an AC failure.
The supervisory unit CSM6, it monitors and controls the operating parameters of the entire system as well as featuring the battery management and support local and remote monitoring through RS-232 and TCP/IP (RJ45).
Last, the heart of the energy shelf, the OT8046 (1080W) switching mode rectifier. It is specially designed for the -48V telecommunication power applications. By using the advanced PWM and zero current soft-switching technologies, the rectifiers perform AC to DC power conversion at high input power factor and efficiency. It is capable of delivering up to 1080W under a wide range of AC input. The rectifier is modular and hot swappable in design. All power signal connections are located on a single connector at the rear of the rectifier. As a result, rectifier installation and maintenance can be carried out swiftly and conveniently.
