Notes to usage
In the electrical characteristics, HD22020-2 rectifier is the same as the convection-cooling rectifier in the usage. But, it is a fan-cooling rectifier. In particular, please pay attention to the following items:
1. Thermal design of the rectifier
The rectifier is cooled through a fan. So, in the design, keep the vent duct from being obstructed by any other objects.
2. Dust-proof design
The fan in the rectifier shall be properly protected from dusts. The dust is the major factor affecting the service life of the fan.
