PowerWatch VDR Features
The PowerWatch VDR records surges, sags, impulses, outages and
frequency variations. It is self powered and easy to use - parameters can be
set by a few easy keystrokes from your PC.
The VDR can retain 4,000 events. The existence of recorded events can be
indicated by the VDR's flashing light.
Communication between a PC and the VDR is carried via the Lite-Link
interface cable. By using this optical data transfer, the PC remains electrically
isolated.
Safety Precautions
The VDR is designed and certified to work only on single-phase systems.
Attempting to modify the VDR or operating it improperly may cause circuit
damage which can ultimately result in property damage, personal injury, or
death.
Plugging in a PowerWatch VDR
The VDR is designed to plug into a standard convenience outlet. As a safety
precaution, the unit should be in a place where it can be easily unplugged.
This will also make it accessible for data retrieval. The VDR does not use a
protective earth connection since there are no exposed metal parts. The earth
conductor is used to measure neutral to ground (N-G) events. The ground
prong may be electrically unconnected (as long as it is not exposed). The
