8.2.1. Supply voltage
The ID ISC.M02-A/B 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.
