8.1.1 PRM ? Stand-alone Operation Setup
This is the nominal configuration, and requires no rework to implement. If the board has
been modified, restore to its original configuration.
1. Solder test leads to signals on the test point header that will be measured.
2. Connect input source to the input lugs. Verify proper polarity. Set to 0 Volts or OFF before
connecting.
3. Connect output to load using the output lugs. Set load to 0 Amps or OFF.
4. Insert oscilloscope probe into J01 if used.
5. Connect DMM to the output test points (V OUT+ , V OUT- ) and to any other signals to be
measured.
6. Set PC Enable Switch (S01_2) to the left position.
7. Apply nominal input voltage.
8. Measure output voltage and verify operation.
9. Use the output voltage trim pot (R 22 ) to adjust the output to the desired level.
10. Apply 100% load, and verify full load operation.
11. Turn off load and power. Proceed to following sections for detailed test procedure.
8.2 PRM – VTM ? Operation, Local Sense
In this configuration, the PRM-CB and VTM-CB are connected together to form a PRM/VTM pair
and regulation is performed at the PRM output. Load regulation will be degraded due to the VTM
output resistance. Tighter regulation can be achieved by implementing non-isolated remote sense
as described in Section 8.3.
8.2.1 PRM – VTM Local Sense Setup
Local sensing is the nominal configuration of the customer board and requires no rework to
implement. If the board has been modified, restore it to its original configuration.
1. Solder leads to any signals on the test point header to be measured.
2. Identify the type of VTM Customer Board to be used (Type A, or Type B).
a. Type A: Install single male-to-male header to X01 only.
b. Type B: Install dual male-to-male headers on X01 and X03.
3. Connect desired VTM board referring to Figure 11 or Figure 12.
4. Connect input source to the input lugs. Verify proper polarity.
Set to 0 Volts or OFF before connecting.
5. Connect VTM output to load using the output lugs. Set load to 0 Amps or OFF.
6. Insert oscilloscope probe into VTM output probe jack.
7. Connect DMM to the VTM output test points and to any other signals to be measured.
8. Set PC Enable Switch (S01_2) to the left position.
9. Apply nominal input voltage.
10. Measure VTM output voltage and verify operation.
11. Use the output voltage trim pot (R 22 ) to adjust the output to the desired level.
a. Do not trim below the minimum input voltage of the VTM used.
12. Apply 100% load, and verify full load operation.
13. Turn off load and power. Proceed to following sections for detailed test procedure.
