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
Voltage | Average operating current | Peak operating current | |
---|---|---|---|
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.
