Ensure that the AC/DC input service is disconnected.
Install the interface cable between the host controller and the ReFlex
Power™ Controller module.
Connect an appropriate output load to the AC power supply module.
Configure the host controller for communications with the ReFlex Power™
Controller module.
Turn on the AC/DC input service, and the power switch on the ReFlex
Power™ Controller.
The modules will first execute a power-on self-test. Also the internal fans are
run at maximum speed for several seconds, and then back to slow speed.
In the following paragraphs, commands include a channel number, [n] . The
channel number corresponds to the slot of the ReFlex Power™
Mainframe where the module is located, counting left to right, 1 through
12. For example:
SOUR[n]:VOLT 5
will be
SOUR1:VOLT 5
for slot-1
SOUR2:VOLT 5
for slot-2
Additionally, model specific parameter values must be added for full scale
voltage and current. They are shown in the following examples as floating
point numerical values,
<fval>
. For the AC power supply modules, the
values are as follows:
Full-Scale Voltage:
140/280V
RMS
Full-Scale Current:
7/3.5 A
RMS
Therefore, the command for full scale voltage would be:
SOUR1:VOLT 140.
Verify communications with the ReFlex Power™ Controller module by issuing
an SCPI
*IDN[n]?
, where “n” is a channel number that corresponds to
