2.9.2.12 Heat Dissipation
The heat dissipation for a DELTA rectifier module will vary depending upon the drive in which it is used.
Losses
The losses for this module may be calculated approximately using:
‘Dirty air’ losses = 2.4 x Total d.c. output current.
‘Clean air’ losses = 90 W maximum.

2.9.2.14 Acoustic Noise
The acoustic noise generated by the DELTA rectifier module itself is negligible. The acoustic noise generated
will be from the fan module MVC3014-4001 and will be specific to each application due to location, air routing
and the use of any grills or baffles. See Section 2.11.1.4
