6.Protect Function
Complete temperature protection sampling. Monitor both PSU and
amplifier simultaneously.
Output power will limit when the temperature of the heatsink higher
than limit value. Output will cut off when temperature higher than the
protect value. Amplifier will restart when temperature return to
normal.
All this series amplifiers has output current protection.
Output current will be limited when exceeds the allowed maximum
value.
When a channel of a amplifier output current exceed the allowed
maximum value (For example,Short circuit). In this case, the
amplifier itself will be disabled (mute) for 1000ms. Amplifier will
restart after the short circuit back to normal.
When input voltage is higher than the upper limit or lower than the
lowest limit, PSU will enter protect mode and cut off the power
supply.
