3 Phase Rectifier, 10KA capacity replaces H-800 series, Magnaflux D-960 series, and 3PH power pack rectifier assy
The 3PH/12SCR/10KA replaces all the old SCR rectifier assemblies used in H,-800, H-700 series, and also power packs, This one assy replaces more than 8 of those tub assemblies in 1/3 of the space. Also provided separately is the pictured mating 3PH transformer for either 6ka or 10ka retrofits.
The SCR’s are rated for 400v, and each one has a overvoltage protector across it..there are only 12 SCR’s needed for reversing dc applications, due to the high ampacity of modern SCR’s. This unit has been used in the field for over 30 years with no failures.
The heatsinks are high quality extruded aluminum, and the 600cfm/1100cfm cooling fan is included with the assy.
