Specifications

When your testing requires a
power supply to do more than
just provide a constant DC
level, the N6750 family of High-
Performance, Autoranging DC
Power Modules and the N6760
family of Precision DC Power
Modules are the perfect fit.
These modules combine a fast
output with flexible controls
and sophisticated measure-
ments. The N6750/60 is more
than a power supply; it is a
stimulus/response instrument.
To fit in 1U, the N6750/60
use an advanced switch-mode
design that offers the low
output noise and fast output
speed typically found on
linear power supplies.
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 com-
mon mode noise. This switch-
ing power supply outperforms
most linear power supplies on
the market.
Output Programming Speed
When it comes to speed, the
N6750/60 achieves perfor-
mance unlike a typical DC
power supply. Thanks to an
active down-programming
circuit to rapidly pull down
the output when lowering the
module’s output voltage, the
N6750/60 can rapidly program
both up and down in voltage.
Changing voltage from 0 V
to 50 V, or 50 V to 0 V, can be
accomplished in less than
5 milliseconds. And for smaller
voltage changes, for example
from 0 V to 5 V or 5 V to 0 V,
the programming speed is
less than 500 microseconds.
These output speeds allow the
N6750/60 to give maximum
system throughput when your
test calls for frequent changes
in power supply voltage settings.
Autoranging for Flexibility
The N6750/60 gives test system
designers even more flexibility
by providing autoranging
outputs. This autoranging
capability provides maximum
output power at any output
voltage up to 50 V. This allows
one power supply to do the
job of several power supplies
because its operating range
covers low voltage, high cur-
rent as well as high voltage,
low current operating points.
For example, the N6751A
High-Performance, Autoranging
DC Module, rated at 50 V, 5 A,
and 50 W can provide full
power at 10 V @ 5 A (=50 W),
20 V @ 2.5 A (= 50 W), 33.3 V @
1.5 A (= 50 W), 50 V @ 1 A
(= 50 W) or anywhere in
between. Therefore, this 50 W
autoranging power supply,
