CC Source Effect
Test category = performance
This test measures the change in output current that results from a
change in AC line voltage from the minimum to maximum value within
the line voltage specifications.
1 Turn off the solar array simulator and connect the ac power line
through a variable voltage transformer or AC source.
2 Connect the current shunt, DMM, and electronic load (see Test
Setup figure B). Connect the DMM directly across the current shunt.
Set the variable voltage transformer or AC source to nominal line
voltage.
3 Turn on the solar array simulator and program the instrument as
indicated in the test record form under “CC Source Effect”.
4 Set the electronic load for the output channel’s voltage under “CC
Source Effect”. The CC annunciator on the front panel must be on. If
not, adjust the load so that the output voltage drops slightly.
5 Adjust the transformer or AC source to the lowest rated line voltage
(86 VAC).
6 Divide the voltage drop (DMM reading) across the current
monitoring resistor by its resistance to convert to amperes and
record this value (Iout).
7 Adjust the transformer or AC source to the highest rated line voltage
(264 VAC).
8 Divide the voltage drop (DMM reading) across the current
monitoring resistor by its resistance to convert to amperes and
record this value (Iout). The difference between the DMM reading in
steps 6 and 8 is the source effect, which should not exceed the value
listed in the test record form under “CC Source Effect”.
Diode Integrity Test
Test category = performance
This test checks the integrity of the series output diode.
1 Turn off the solar array simulator and connect the output as shown
in Test Setup figure D. The shorting wire should be about #16 AWG.
2 Turn on the solar array simulator and set the output voltage to 5 V,
and the output current to the rated current. Turn the output on.
3 Observe the voltage displayed on the front panel. The voltage should
be between 0.5 V and 0.8 V. The current should be at Iset in CC
mode. If the voltage is below 0.5 V (about 0.1 V @ Iset and CC), the
diode is shorted. If the voltage is above 0.8 V (about 5 V @ 0 A and
CV), the diode is open.
