4.6 Mains operation and resulting temperature
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 (P
d
). The amount of heat resulting from
power dissipation might remain inside of a rack‑shelf and needs to be diverted using
appropriate measures.
Mains operation and resulting temperature tables allow the determination of power supply
and cabling requirements. The tables are meant as auxiliary means for calculating
temperatures inside of a rack-shelf system/cabinet and the ventilation efforts necessary.
The column P
d
lists the leakage power in relation to different operational states. The column
BTU/hr lists the dispensed heat amount per hour.
