Remote Sensing Capability
Voltage Drop Per Lead:
Load Voltage:
Up to 1/2 of rated output voltage.
Subtract voltage drop in load leads from specified output
voltage rating.
Load Regulation:
Degradation due to load lead drop in--output: mV (regulation) = Vdrop(R
sense
-)
Degradation due to load lead drop in + output:
mV (regulation) = V
drop
(R
sense
+) + 2V
drop
(V
rating
)/(V
rating
+ 10 V)
where R
sense
_ and R
sense
+
are resistances of respective sense leads.
Maximum Reverse Voltage Current Sink Capability: *
With ac input power applied and the dc output reverse biased
by an external dc source, the supply will continuously
withstand without damage a current equal to its output
current rating.
* Current must be limited by user's external dc source.
Maximum Input Power:
9000 VA,
7950 W,
175 W (with no load)

Output Voltage Programming Response Time**
Programming Rise/Fall Time (time for output to change from 90 % to 10% or from 10% to 90% of its total
excursion):***
45 ms 60 ms 100 ms
Full-load programming speed up/down time (time for output to settle within 4 LSBs of the final value):***
150 ms 185 ms 280 ms
No-load downprogrammiug discharge time (time for output to fall to 0.5 V when programmed from full voltage
to zero volts):
340 ms 650 ms 870 ms
