Heatsink
The cooling fans in the DCREG build up dust from air intake.
Check if the heatsink is clean.
If the heatsink needs to be cleaned, please contact Elettronica Santerno Customer Service.
Cooling fans
The minimum expected durability of the cooling fans of the DCREG is approx. 50,000 hours. Actual
lifetime is based on the operating conditions of the converter, the ambient temperature and the
environmental pollution.
The signs for imminent possible failures are noisy bearings of the fans or worn fins of the fans although
regularly cleaned.
If the DCREG is used in a crucial stage in a process, consider replacing the cooling fan as soon as these
symptoms occur.
Please contact Elettronica Santerno Customer Service to replace the cooling fans.
