10 Operational Ratings and Characteristics
NOTICE
Never Exceed the absolute maximum ratings! Keep the power supply voltage
below the upper limit of +30V! Otherwise the board electronics will seriously be
damaged! Especially, when the selected operating voltage is near the upper limit
a regulated power supply is highly recommended.
