Power Supply Priorities
...
Power supply line | Description |
1 |
This is the main power supply line. The system chooses the power supply input with the biggest Voltage. That is why this power line always has the highest priority. |
2 |
This power line has the second priority and will start working only if there’s a power outage on power line 1. Normally each of these lines supply the system with 11V. Power switching is instant. |
3 |
This power line has the lowest priority because it has the lowest voltage. VT-ACCU or VT-BAT can be connected on this power line. VT-ACCU is charged by the power line 1. The system will start working from VT-ACCU only in case power lines 1 and 2 fail (power outage). VT-BAT battery is not charged. Once it is depleted, the battery has to be manually changed. |
