to
choose suitable
current for
module |
|
|
The marked
current of
module is the
maximum
allowable
current in
normally working
conditions.
Considering
thyristor’s
low ability of
anti current
impact, we
sincerely
suggest you keep
some surplus
when choosing
module.
Resistance
load: marked
current of
module should be
two times as
high as rated
load
current.
Inductance
load: marked
current of
module should be
three times as
high as rated
load current. |
