Brief introduction:
This inline blocking diode assembly which contains 1,500V 25A industrial diode inside Aluminum enclosure, the diode sit on bottom surface of the enclosure directly to gain better heat dissipation. It downsizes enclosure (combiner) dimension due to blocking diodes are moved out of enclosure (combiner).
