Description

Universal line input to + and -24 V DC output designed for audio applications. The supply uses a two switch fly back topology with a low cost LM5021 controller. The supply is designed to handle 150 watts peak power required by an audio amplifier but thermally designed for the lower average power common in audio applications.

Features
  • Universal line input
  • High peak power
  • Low cost
