Hi Ron,

Yeah, in looking for a replacement, I researched the LinkLite and LiinkPro; as
you've surmised, my question WRT application concerns the prescaler. From what
I've read, it appears that the new models can't be used *directly* (i.e.,
readout 0identical to a Link 10) as a pack voltage monitor. But it should still
be usable, e.g., 161V would display as 16.1V. There appears to be a slight
dimensional difference, as well.

As for raiding Marine suppliers and what not, no luck so far. Apparently it was
back MD'd back in February ,, a bit of time for stock depletion.

The Link 10 appears to be the only product that supported a prescaler.

is fed from pin 5 at the terminal block on the back of Link 10. If the battery
bank reaches higher than 40 V, the power should be tapped from a more suitable
point or a DC to DC converter should be used. The DC to DC converter should meet
the power requirements of your system. In electric vehicle applications, the use
of a converter is important to prevent voltage drops that occur when the system
is tapped during acceleration. For most alternative energy sites or high voltage
packs, tap the battery between 18 and 24 V (reference from the negative of the
bank). This will ensure the voltage to pin 5 is stable and remains within Link
10's specifications.

When installing the prescaler, do not connect the prescaler's input negative to
any other location other than load side of the shunt. It is imperative that the
prescaler is installed properly or permanent damage to Link 10 will result.

voltage, or cause no display.

output. A continuity check should display 0 Ohms between the black wires when
the prescaler is not connected. A resistance check between the red wires will
vary depending on the model of Prescaler.

while the prescaler is not hooked up to Link 10, you will get an erroneous
reading. If the resistance checks are sufficient, go ahead and connect Link 10
between pins 1 (Ground) and 4 (Voltage Sense). Measure the voltage between the
same pins. A 10:1 ratio on the display should appear for the 500V model (i.e.
read 30V on the output for a battery voltage of 300V). A 2:1 ratio should appear
on the display for the 100V model (i.e., you read 30V on the output for a
battery voltage of 60V). It is imperative that the input and output wires be
hooked up in the proper places with correct polarity. Failure to do so can
destroy Link 10 or the prescaler.

wired in another location, you run the risk of destroying Link 10 if the battery

source) is operating.

If the voltage is less than 100V do not use a 500 V prescaler. Link 10 will make
certain assumptions about the batteries based on the model of prescaler. Certain
functions may not be programmed properly if using a 500 V prescaler on a system
less than 100 V. For example, volts, amps, amp hours and time remaining would
still be displayed, however, it would not be possible to employ all of Link's
features.
