Cooling by forced ventilation
Required:
ƒ Forced ventilation by one or several fans.
ƒ Air speed: 2.5 m/s at the MP measuring point
– For fan dimensioning: Corresponds to a volume flow of 0.5 m
3 /min (17.6 CFM) per
50 mm device installation width.
Permissible:
ƒ Operation with continuous output current I

Cooling by means of natural convection
Required:
ƒ Unhindered ventilation by means of natural convection (no fan required).
ƒ Ambient temperature: T
