PROTECTION SYSTEMS

Output over current: Initially gain reduced to maintain control, persistent over current causes shutdown
Over temperature: limiters applied, persistent over temperature causes shutdown
Mains Brownout: Automatic protection & recovery
Switch on surge: Soft-start current inrush limiting
DC on output: Immediate shutdown, power cycle to recover

THERMAL

One variable speed fan per pair of channels and additionally one variable speed fan per unit
Airflow is from the rear to the front
