Notes for AC Electrical Characteristics
Note 1) Delay is proportional to the capacitor values with minimum allowed value of C
Note 2) Depends on C
Note 3) C
Note 4) Pulse width is proportional to C1PH. Maximum allowed values of C
Note 5) Power up delay is set by C
Note 6) Ramp time is proportional to the capacitor value.
Note 7) This value corresponds approximately to 15V minimum SCR firing voltage. For 15V minimum SCR firing voltage,
Note 8) PPUBAL applies to steady operation, is deviation of any firing point to closest balanced set of firing points.
Note 9) Firing angle is defined with respect to zero delay (ie. max output voltage.
