that spreads the energy of switching noise, helping devices meet electromagnetic interference standards more easily. Protective Suite : Includes comprehensive safety features such as: Thermal shutdown Current limit and soft start Overvoltage protection (OVP) Jotrin Electronics Common Applications str f6267 datasheet pdf
For troubleshooting, a common practice is to disconnect the load (e.g., the horizontal output transistor) and connect a dummy load (like a 60W incandescent lamp) to the main B+ output. If the lamp lights up and the B+ voltage is present and stable, the STR-F6267 is likely functional, and the fault lies elsewhere in the secondary circuits.
