On the N67xxA modules,
the OV trip point can be
programmed up to 60 V on all
50 W and 100 W output modules.
When overvoltage protection is
enabled, the power supply will
turn off its output if the output
voltage reaches the programmed
overvoltage limit. The voltage is
measured at the output termi-
nals. There is no SCR crowbar
nor is there a fixed overvoltage
threshold in any of the N67xxA
modules. When an overvoltage
occurs, the OV enunciator will
appear next to the channel
number in the bottom left corner
of the display and the OV status
bit is set for that output.
662xA OV Trigger Connections
Each output of the 662xA
power supplies has two OV
terminals on its rear panel
terminal block labeled +OV
and –OV. By connecting these
terminals in parallel, an over-
voltage shutdown on any one
output will also trigger the
overvoltage on the remaining
outputs. Up to eight terminals
can be strapped together.
The N67xxA Modules lack
these OV terminals, but not the
functionality. The functionality
is achieved in firmware by
using the “OUTPut:PROTection:
COUPle <on, off, 0, 1>” com-
mand. This command enables/
disables output coupling for
protection faults. When enabled,
ALL output channels are dis-
abled when a protection fault
is triggered. When disabled,
only the affected output channel
is disabled when a protection
fault is triggered. This eliminates
the need for physical OV
terminals. The standard RI/DFI
on each N6700A/B mainframe
extends this functionality to
more than one mainframe.
Please refer to the Digital
Control Connections section
of the N6700 User’s Guide for
more information on configuring
the digital port for RI/DFI.

Overcurrent Protection
662xA: When the Overcurrent
protection feature is enabled,
and the output is sourcing cur-
rent and enters +CC operating
mode, the output will be
disabled (set to zero volts and
minimal current) and the word
OVERCURRENT will appear
on the front panel display.
The OC status bit is set for
that output.
N67xxA Modules: When over-
current protection is enabled,
the power supply will turn off
its output (set minimum volt-
age, minimum current, and
goes into a high-impedance
state) if the output current
reaches the programmed cur-
rent limit. The output current
is measured across a current
shunt resistor on the inboard
side of the output terminals.
When an overcurrent condition
occurs, the OC enunciator will
appear next to the channel
number in the bottom left
corner of the display and
the OC status bit is set for
that output.
Unregulated Output,
Overtemperature, and Errors
Operation and handling
is the same between the
662xA and the N67xxA
modules.
