Both the CR-150-R5 and CR-160-R8 evaluation boards can be powered in either of two methods: The first method is to apply both positive and negative 12V from your own power supply to terminals on the evaluation boards. The second method is to apply power using a (floating) 24V wall mount power supply. The CR-24V power supply is offered for just this purpose.
The CR-24V power supply is suitable for use internationally, and includes adapter blades for various wall socket types and AC supply voltages found worldwide.
