Power Line Disturbance Analyzer
If you are responsible for pre-installation
site surveys, the maintenance of computers and their
peripherals, power surveys, or troubleshooting
sensitive industrial or commercial equipment, the
Dranetz Series 646 Power Line Disturbance Monitor
was designed with you in mind.
Available in both single-phase and
three-phase versions, the 646 can continuously
monitor and record power line sags and swells, under
and over-voltages, impulses, and frequency variations
on both phase-to-neutral and neutral-to-ground . A separate
DC channel is also provided for easy correlation of DC
power supply disturbances with AC power line disturbances.
Standard features include user-friendly,
menu-driven operating controls with alphanumeric display for prompting,
environmentally protected membrane keypad, real time clock, nonvolatile
data and setup memory, built-in thermal printer, and RS232C interface. A
temperature probe is available as an accessory.
Also available, three options provide
impulse duration measurements, an uninterruptible power supply, and an
integral direct connect, auto-answer, Bell 103-compatible modem. Separate
OPERATE and PROGRAM modes, menu listing of all commands and programmable
parameters, and two-key selection of the appropriate function through NEXT
MENU and NEXT CHOICE keys makes operation easy . . . even for the
infrequent user . The 646 is shipped with pre-programmed standard limits.
If these limits are suitable for the application, it is only necessary to
turn the power switch to the ON position to start basic monitoring
operation. Results are clearly printed in exact order of occurrence, as a
complete listing of all disturbances or in summary format and fully
annotated with numerical values, informative descriptors, and the exact
time and date of occurrence for easy analysis.
Available Models
Dranetz 646-1:Monitor
and record impulses, sags, surges,undervoltages,
over-voltages and frequency variationson a single
channel of AC voltage, neutral to ground voltage
channel, and a single channel of DC voltage.
Dranetz 646-3:Monitor
and record impulses, sags, surges,under-voltages,
over-voltages and frequency variations on a single
channel or 3 channels of AC voltage(total of 4 AC
channels available), neutral to ground voltage
channel, plus a single channel of DC voltage.
