The AD-M2KPWR-EBZ is an ADALM2000 add-on board which increases the output current capability up to 700mA. This board can be also used as a standalone benchtop power supply with positive and negative outputs.

The AD-M2KPWR-EBZ is a USB Type C powered board capable to increase the output current of ADALM2000’s power supplies.
Outputs: (2 control modes)
AD-M2KPWR-EBZ must be supplied either from a 5.1V 3A USB Type C power adapter or from a lab supply using the screw terminal connector. Make sure that the jumper on the P2 connector is on the position corresponding to the chosen supply:
Figure 3. AD-M2KPWR-EBZ supply select jumper
|P2||Selected supply method|
|Jumper 1-2 shorted||Vext - for external lab supply|
|Jumper 2-3 shorted||Vusb - for USB Type C power adapter|

In M2K mode the board is plugged into ADALM2000. After that, the programable user supplies of ADALM2000 can be used as usual, but they will source more current. The jumper on the connector P7 must be in M2K- position and the jumper on the connector P6 must be in M2K+ position.
Figure 5. AD-M2KPWR-EBZ POT/M2K mode setup jumpers
|Jumper 1-2 shorted||Positive supply adjusted by R20||( 1.5 → 15V)|
|Jumper 2-3 shorted||Positive supply of M2K||( 0V→ 5V)|
|Jumper 1-2 shorted||Negative supply adjusted by R19||( -15V → -1.5V )|
|Jumper 2-3 shorted||Negative supply of M2K||( -5V → 0V)|
In POT mode the board can be used as a standalone benchtop power supply. The output voltage is adjusted with potentiometers R19 and R20. The output voltage will be available at the same pins: V+ and V-.
The board can be adjusted such as the output voltage is double or triple than the value set from the M2K. This feature is only available in M2K mode, and it is activated by soldering or desoldering the solderjumpers on the bottom of the board according to the table. You can find the table with the soldering instructions on the bottom of the board.
