Application Specific DC Power Supplies tailored solutions for specific needs
Non-volatile memory can store a
maximum of 3500 points. The tables
(I-V curves) are easily stored and
recalled with an IEEE-488.2 com-
mand. The table(s) stored in this
memory will be retained when the
power is turned off. Volatile memo-
ry greatly increases the flexibility
by saving up to 30,000 points.
Multiple tables are easily accessed
with IEEE-488.2 command. These
tables will be erased after power
is removed.
In Table Mode, current and voltage
offsets can be applied to the select-
ed table to simulate a change in the
operating conditions of the solar
array.
3. Fixed Mode: This is the default
mode when the unit is powered on.
The unit has the rectangular I-V
characteristics of a standard power
supply, when an output capacitor is
added in this mode.

Load Switching Recovery Time: < 5 µs when
switched from short circuit to variable
load, to within 1.5 A of an operating point
on the I-V curve.
Remote Sensing: Up to 2 V+ (Voc-Vmp).
Add 3 mV to the voltage load regulation
specification for each 1 volt change in the
positive output lead due to load current
change.
