Power Requirements
Your system requires a clean, steady power source for reliable performance of the high frequency CPU
on the product, the quality of the power supply is even more important. For the best performance makes
sure your power supply provides a range of 12V DC power source.
Power Consumption
For typical configurations, the CPU card is designed to operate with at least a 36W power supply. The
power supply must meet the following requirements :
-
Rise time for power supply: 2 ms - 30 ms
The following table lists the power supply's tolerances for DC voltages:
