SP-48 Frequently Asked Questions (FAQs)

  • The recommended operating frequency range for the SP-48 is 50 kHz to 200 kHz, but it can be used up to 500 kHz with reduced performance.
  • Yes, the SP-48 can be used in a push-pull configuration, but it's essential to ensure that the primary windings are properly connected and the transformer is designed to handle the increased voltage stress.
  • The maximum allowable temperature rise for the SP-48 is 40°C (72°F) above the ambient temperature, but it's recommended to keep the temperature rise below 30°C (54°F) for optimal performance and reliability.
  • The SP-48 is designed for low-voltage applications, but it can be used in high-voltage applications with proper insulation and creepage distance considerations. However, it's essential to consult with Triad Magnetics or a qualified engineer to ensure the transformer is designed and used safely.
  • The recommended wire size for the primary and secondary windings depends on the specific application and current requirements. As a general guideline, use 18-20 AWG wire for the primary winding and 20-22 AWG wire for the secondary winding.
