4.1.2 Other Requirements
Short Circuit Protection at Output Stage
The amplifier should be protected so that no functional failure
occurs when it is operated with a short across its output stage
for 2 minutes. The amplifier should recover after removing the
short condition.
Over Voltage Protection
In case a regulation loop in the unit gets defectives, the output
voltage shall not exceed more than 30% of the nominal value.
Thermal Protection
There should not be any breakdown or activation of any
protection circuit during the entire thermal profile test. Refers to
the Therma
l Profile test stated in Reliability Test Plan for
Multimedia Powered Speaker System.
Environmental Conditions
The unit should work between +5 C till 45 C under ambient
temperature.
The unit should not get damaged within the temperature range
of +5
C till 60 C ambient temperature.
