Stack Diode
These diodes are used in the old EV2 and EV4 SCR based machines.
Due to the design of these older machines, always be sure when replacing these Diodes to replace the two bottom or two top in pairs. Also ensure all diodes in each stack are the same part number. Call us here at Thermo International for cross reference help, many OEM suppliers private labeled their Diodes and we may be able to help.

Comm/Choke SCR
These SCR’s ware used in the old EV2 SCR based machines in the Commutation circuit and the Choke circuit. These are a direct replacement part.
SB019
Main SCR
This Main SCR is used in all the old EV2 SCR based units. This SCR is a direct drop in replacement part.
SB020
Positive Rectifier Diode
These Positive rectifier diodes are used in all the old EV2 systems, used in groups of 3 positive and 3 negative they rectify the three phase line voltage to Direct Current for the Rectifier buss within the machines. These are a direct drop in replacement part.
SB021
Negative Rectifier Diode
