Power supply requirements
2022-02-02Last updated
When calculating power usage of your access control system, you must account for the power requirements of the Synergis™ Cloud Link appliance as well as other connected hardware.
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 card reader power consumption information can help you to plan your access control system power requirements.
| 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.
