APS General Information
APS N6900 Series and N7900 Series
power supply power requirements
Connect the power cord that was
supplied with your unit to the AC
mains connector on the rear of
the unit. Note that these cords are
standard and are specially rated to
handle the power needs of the APS
supply they are shipped with. The
AC input on the back of your unit
is a universal AC input. It accepts
nominal line voltages in the range of
100 VAC to 240 VAC. The frequency
can be 50 Hz, 60 Hz, or 400 Hz. AC
mains rated below 180 VAC cannot
supply enough current to power
either the 1 kW or the 2 kW N6900
and N7900 models to their full rated
output power. In such cases, when
a 1 kW or 2 kW APS power supply
is connected to below 180 VAC AC
mains, the power supply will still
operate normally, but its maximum
output power will be limited to 700 W.
In this condition, if the power supply
exceeds 700 W of output power the
instrument turns off the output and
sets the CP+ status bit.
APS power supply connectivity
All APS power supplies come
standardwithGPIB(IEEE-488),
LAN(LXICore),andUSBremote
programminginterfaces.GPIBand
LAN parameters can be set via the
frontpanel.TheAPSisLXICore
2011 compliant and includes a
built-in Web interface. This means
you can control the APS remotely
using a Web browser and a LAN
connection.
Single Output: 1 & 2 KW GPIB, LAN (LXI Core), USB
