Compact Power Supply AC Requirements
The GV K-Frame XP 8-RU Power Supplies have provision to support up to three hot
swappable power modules. These convert the AC line input to 48V DC for the Video
Processor Frame. The cells for the three modules (referred to as left, center, right) are
identical and any or all cells can have a module installed. Each cell has its own AC line cord.
The supplies are power factor corrected and automatically accommodate low line (120V
nominal) or high line (240V nominal). The power supplies have a rating of 90-140V AC for
low line and 180-240V AC high line to accommodate under and over voltage conditions.
The 8RU Frame is supplied with two power modules. A third power module can be fitted as
