3.2 Mounting in cold−plate design
The ECSCE... modules are intended for mounting in cold plate technique (e.g. on
collective coolers).
Requirements for collective coolers
The following requirements must be met to ensure safe and reliable operation
of the power supply modules:
ƒ Good thermal contact with the cooler:
– The contact surface between collective cooler and power supply
module must be at least as large as the cooling plate of the power
supply module.
– Smooth contact surface, max. deviation 0.05 mm.
– Use all prescribed screwed connections to connect the collective cooler
to the power supply module.
ƒ Comply with the thermal resistance R
th
according to the table.
– The values are valid for operation of the power supply modules under
rated conditions.

ƒ Ambient conditions:
– The rated data regarding the ambient temperature remain valid for the
power supply modules (
^ 68 ff.).
– Temperature of the cooling plate ("cold plate"): max. +85 °C
