Power supply requirements

2024-07-08Last updated

When calculating the power usage of your access control system, you must account for the power requirements of the appliance and other hardware connected to the same power supply.

power consumption

During normal operation and bootup 12 V dc 300 mA 600 mA

Card reader power consumption

The following power consumption information on the card reader can help you to plan the power requirements for your access control system.

HID card reader Standby average current a Reading average current b Peak current c
20 60 mA 70 mA 250 mA
20K 65 mA 75 mA 250 mA
40 65 mA 75 mA 250 mA
40K 70 mA 80 mA 250 mA

a Standby average current: RMS current draw without a card in the RF field.

b Read average current: RMS current draw during continuous card reads.

c Peak current: highest instantaneous current draw during RF communication.
