Introduction
Welcome
The HPE-300/HPE-300-2AC is a combined power supply and SMPTE Hybrid Fiber Extender
for Grass Valley’s LDX 100 and other LDX studio cameras. The power supply is specifically
developed for cameras using 300 VDC.
The HPE-300/HPE-300-2AC is key components of Grass Valley’s unique NativeIP and
Di) workflows where the camera’s video, audio and control/data signals are sent
directly to a network IP switch. Additionally, the HPE-300/HPE-300-2AC can be used in
conventional applications where local power of a camera is needed.
Due to the high density of equipment installations, the HPE-300/HPE-300-2AC is built in a
small package that measures only 2RU height and 1/3 unit wide. This allows to install three
units side-by-side in a standard 19”rack using the optional rack mount shelf (HPE-TRAY).

Technical overview
The primary function of the HPE-300/HPE-300-2AC is to convert an incoming AC mains
power source, compatible with all international voltage and frequency standards, to a fixed
300 VDC, 300 W output to power Grass Valley’s studio cameras.
Safety features are incorporated to assure that the interconnecting SMPTE Hybrid Fiber
cable and associated connectors between the HPE-300/HPE-300-2AC and the camera are
intact and safe before the 300 VDC is applied.
The HPE-300 is equipped with a robust power supply providing all necessary safety and
control circuits designed specifically to operate Grass Valley studio cameras and including
