A528 OEM UHF Multiregional compact reader Revision date: 02/04/2008 Revision: 2 Power supply connection In the following schematic suggested A528 power supply connection is shown. The use of fuse F1 is recommended since A528 doesn't provide internal current limitation protection. Diode D1 avoid damage to the reader in case of reverse polarity connection. The use of optional LC filter improves reader immunity in presence of noisy power supply.
