*Rectifiers can be manufactured with air natural (AN) and air forced (AF) cooling (according to EN 50328). Air forced cooling is actually combined natural air and forced air cooling. The rectifier operates with natural cooling under loads lower or close to the rated ones. In case of risk of diodes overheating under overloads, fans are switched on and force-cool the diodes. Fans switch off automatically after overload disappearance and diodes temperature drop.
** RMS current value per any 8 hours during the day should not exceed rated current.
*** RMS current value per any 30 minutes should not exceed rated current, and if during these 30 minutes 100 % overload takes place, the averaging time should be 5 minutes.
