Features
- ADALM2000 compatible
- USB Type-C powered
- Provides two outputs with increased current sourcing capabilities
Description
The AD-M2KPWR-EBZ is a USB Type C powered board capable to increase the output current of ADALM2000’s power supplies.
Inputs:
- USB type C: 5.1V (Raspberry Pi power adapter- not provided in the kit)
- External (screw terminal connector): 4.5-18V
Switching between the inputs is done with a jumper.
Outputs: (2 control modes)
- Two variable power supplies that track M2K user supplies:
- 0V to 5V (400mA in USB power mode)
- -5V to 0V (400mA in USB power mode)
- Two variable power supplies, controlled from a potentiometer
- 1.5V to 15V (up to 700mA if powered with 18V)
- -15V to -1.5V (up to 700mA if powered with 18V)
Applications
- General-purpose electronic systems
- Educational applications
- Automated test equipment
Package contents

Getting started
AD-M2KPWR-EBZ and 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:
Vext - for external lab supply Vusb - for USB Type C power adapter
The board has two modes: M2K and POT
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.

In POT mode the board can be used as a standalone benchtop power supply. The output voltage is adjusted with potentiometers R19 and R20.
