Power Supply
The Power Supply for the Vision Controller has the following requirements:
- Voltage typical 3.3V (Max 3.6V, Min 1.7V)
- Maximum Current: 20mA
- Vision Controller Sleep current: 14uA
- Vision Controller typical operating current: 10mA
The power supply for the controller must be always available and may not switched off. If the fixture contains a battery the Vision controller should be supplied from the battery. This is necessary to support battery wake up from the NFC for example and for preserving information in the RAM.
A block diagram of the schematic for the Vision Controller regarding power supply and state inputs may look like this if it is a battery supplied fixture:
There a different ways how this can be done. Depending on your on the fixture and how good you support the features here is an overview on how you could implement it. The Schematics contains simple blocks to get you the idea.
| Fixture Type | Description | Support IR Wake Up | Support NFC Wake Up | Support Antitheft Stay On | Example Schematic |
| Grid powered (AC powered) fixture | This type of fixture does not have a battery inside. It just is powered by the grid. | NO | NO | NO | — |
| Grid powered fixture (AC powered) + Battery for configuration | This type of fixture does have a battery inside but just for the logic and not for powering for example the leds. It allows the fixture to be configured while not powered from the grid. | NO | YES (for configuration) | NO | — |
| Single Cell Battery Fixture | This type of fixture have a battery inside which powers also the actuators like the leds. The Battery Voltage is typical 3.7V. | YES | YES | YES | https://kk-t.com/wp-content/uploads/2024/12/PowerSupplyExampleExt_Batterie_SingleCell.pdf |
| Multi Cell Battery Fixture | This type of fixture have a battery inside which powers also the actuators like the leds. The Battery Voltage is higher than 5V | YES | YES | YES | https://kk-t.com/wp-content/uploads/2024/12/PowerSupplyExampleExt_HighVoltage.pdf |
