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 Synergis™ Cloud Link appliance and other hardware connected to the same power supply.
Synergis Cloud Link power consumption
| Synergis Cloud Link | 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.
