Note 1 :

The output short circuit currents are tested one channel at time.

During a short circuit a large consumption of power occurs, anyway the thermal protection circuit guarantees the temperature not over-

comes high value.

Safe permanent short-circuit is only guaranteed for input voltages up to 16V.
