Protection
TRA-Series Amplifiers come standard with several protection circuits:
Output over-current protection - The output current is limited to safe levels
regardless of load.
DC output protection - The amplifier is switched off if more than 2 volts of
dc is present on the output. The amplifier will automatically restart after 5
seconds (if no fault remains). The protect LED is lit as well as the clip LED of
the affected channel(s).
Main supply rail overvoltage protection - The amplifier is switched off if
the main supply rails have too high of a voltage. The amplifier will
automatically restart after 5 seconds (if no fault remains). The protect LED is
lit as well as the clip LED of the affected channel(s).
Chassis internal temperature monitoring - The amplifier is switched off
when the internal ambient temp reaches 70º C. The amplifier will again switch
on when the internal ambient temp reaches 55º C. The protect LED is lit as
well as the clip LED of ALL channels.
Inrush limiting - The turn-on current is limited. This is active during initial
startup as well as when exiting standby mode.
Mains fuse - There is a 5 amp time delay fuse.
