General Components
1. Remote Sense PRM (PS10)
2. Input lugs: Sized for #10 hardware. Use these for making connection to the input
source. This board does not contain reverse polarity protection. Check for proper
polarity before applying the power.
3. Input fuse (F10): Appropriately rated.
4. Input filtering: Input capacitor (C
IN
) and filtering (inductor and ceramic
capacitors) allows for stable operation with most input sources. Sockets can be used
for easy installation of aluminum-electrolytic input capacitor. It is recommended to
place the 22 uF, 100 V input electrolytic capacitor in the sockets at the
input of the PRM ® .
5. Enable/Disable switch (S11) and FET switch: When actuator is in top position
towards “ON” text on the board, the ENABLE pin will be open and PRM device
will be enabled. When actuator is in bottom position towards “OFF” text on the
board, the ENABLE pin will be connected to SGND and PRM device will be disabled.
When switch S11 is ON, open drain FET can be selected to control the ENABLE pin
using external source.
6. Header-jumper for Adaptive Loop control (P10): Provides the option to select and
enable Adaptive Loop control.
Note: Not Populated for Remote Sense PRM Evaluation Boards.
7. Header-jumper for trim control (P11): Provides the option to select and enable the
trim control.
Note: Not Populated for Remote Sense PRM Evaluation Boards.
8. Operating Mode selection switch (S10): For selecting one of the following
operating modes:
a. Slave Operation (used in PRM paralleling)
b. Remote Sense: Local sensing (single ended)
c. Remote Sense: Non-isolated remote sensing (differential)
9. Output lugs: Sized for #10 hardware. Use these lugs to connect the output directly
to the load.
