Optothyristor
Optothyristors of types T0125-10, TO125-12.5 are used in DC
and AC circuits of various installations. A distinctive feature
of optothyristors is the absence of a galvanic connection between the
control terminals and the power terminals. Optothyristors can be operated
at ambient temperatures from minus 60 to plus 45 ° C, atmospheric
pressure (86… 106) kPa, relative humidity up to 98% at a temperature of
35 C without condensation of moisture. Climatic design And, category
placement of U2, T3, HL2 according to GOST 15150-69 to GOST 15543-70. It is allowed
to operate optothyristors at higher temperatures with
a corresponding reduction in load current
