2.Suggested Heatsink - powersoft IpalMod User Manual

Considering that thermal protection of the module (T
set at 75°C (167°F) on the bottom aluminium plate and stat-
ing an ambient temperature of 45 °C (113°F), the previous
example gives:

8 : 2.Suggested heatsink

Powersoft provides an IpalMod compatible aluminium alloy
heatsink, specifically designed to house the amp module,
an input/output interface and the AC mains connection

) is meaning that the temperature of the bottom plate is always
lower than 75°C if the heatsink has a thermal resistance bet-
ter than 0.14°C/W (or 0.14 K/W) with ambient temperature
up to 45 °C.
