Mounting in cold−plate design
The ECSCE series power supply 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.
