DC power modules offer low
noise outputs
Careful attention has been paid to this
design to ensure low normal mode noise
(ripple and peak-peak) as well as low
common mode noise. While all DC power
modules are switching power supplies, the
N6750 high-performance autoranging DC
power modules, the N6760 precision DC
power modules, and the N6780 Source
Measure Units are switching power supply
designs that outperform most linear power
supplies on the market.
DC power modules provide fast
voltage changes
When it comes to speed, the N6750
high-performance autoranging DC power
modules, the N6760 precision DC power
modules, and the N6780 Source Measure
Units achieve performance unlike a typical
DC power supply. Thanks to an active
down-programming circuit to rapidly pull
down the output when lowering the output
voltage, these power modules can rapidly
program both up and down in voltage.
Changing voltage from 0 V to 50 V, or 50 V
to 0 V for example, can be accomplished in
less than 1.5 milliseconds.
Note that for smaller voltage changes,
from 0 V to 5 V or 5 V to 0 V for example,
the programming speed is less than 200
microseconds. These output speeds
allow the N6750/60/80 to give maximum
system through-put when your test calls
for frequent changes in power supply
voltage settings.
Autoranging for exibility
The N6750 high-performance auto-
ranging DC power modules and the N6760
precision DC power modules give you even
more flexibility by providing autoranging
outputs. This autoranging capability
provides maximum output power at any
output voltage up to 60 V. This allows one
power supply to do the job of several power
supplies, because its operating range cov-
ers low voltage, high current as well as high
voltage, low current operating points. For
example, the N6755A high-performance,
autoranging DC module, rated at 20 V, 50
A, and 500 W can provide full power at:
10 V @ 50 A (= 500 W),
20 V @ 25 A (= 500 W),
15 V @ 33 A (= 500 W),
or anywhere in between.
Therefore, this 500 W autoranging power
supply, due to its extended
voltage and current range, can produce
voltage and current combinations in the
range of a 1000 W non-autoranging
power supply.
