Note 1: “The 48 volt 50 amp filtered chargers have two C1 and C2 capacitors and two sets of D1 and
V1. The unfiltered 50 A charger has two C1 capacitors and two sets of D1 and V1.”
Note 2: “With the 48 volt 50 amp charger it is recommended to replace both SCR’s at the same time if one is
shorted or open. The #13716S is for only one SCR.”
