3.2.1. Supply voltage
The ID CPR.M02 must be supplied only by a regulated power supply. If switching power supplies
are used with the module, be sure that there is adequate filtering. Noise from the power supply can
result in a reduction of the read/write range of the module. The cable length from the power supply
should be as short as possible, and should in any case not exceed 3 m.
