Note Design for a possible overvoltage of 20%
Temperature switch C1B–B110 (110°C) , of TMC or similar
Observation
Windings 20V e 25V, and windings 46V e 42V, are not loaded togheter.
Windings of 42V must be designed in such a way that at 10A
concurrence for about 100ms the c.d.t is less than 3V (effective).
Because the housing is the external attachment, ad es.

Mounting: Ring base transformer on mounting plate with central through hole.
