MAINS OPERATION & RESULTING TEMPERATURE

MAINS OPERATION & RESULTING TEMPERATURE

The following tables allow determining power supply and cabling requirements.

The power drawn from the mains network is converted into output power to feed the connected loudspeaker systems and into heat. The difference between power consumption and dispensed power is called power dissipation (Pd). The amount of heat resulting from power dissipation might remain inside of a rack-shelf and needs to be diverted using appropriate measures. The following table is meant as auxiliary means for calculating temperatures inside of a rack-shelf system/cabinet and the ventilation efforts necessary.

The column „Pd“ lists the leakage power in relation to different operational states. The column „BTU/hr“ lists the dispensed heat amount per hour.
