Description
The Ultra SlimPak II is an exciting
new line of isolating signal
conditioners from Action Instruments
with greater accuracy and better
stability than virtually any
other signal conditioners on
the market today. The Ultra
SlimPak II features Smart Power,
which eliminates wasted power
for low loop resistance loads
in the current output mode.
The
WV418 supports 2-wire, 3-wire
or 4-wire Pt100 RTDs with alphas
of either 0.00385 or 0.00392,
as well as Cu10. Ranges are
DIP switch selectable or (optionally)
PC programmable. Outputs include
0-10V, 0-20mA and 4-20mA.

Smart
Power
The Ultra SlimPak II uses Smart
Power to control its output
supply. Smart Power automatically
adjusts the the voltage to drive
the output loop to the required
current. A low impedance current
loop will subsequently require
less voltage than a loop with
higher impedance. Previous designs
provided only a single supply
at the highest voltage required
to drive the highest impedance
load. Using Smart Power results
in power savings and reduces
the operating temperature of
the signal conditioner.
