Description

This power supply is ideally suited for use with amplifier projects. The regulated 5 VDC, 60A design is capable of delivering 350watts of output. Overload, over voltage, and over temperature protection is built-in, shutting down the power supply to prevent damage and then restoring power upon recovery.

  • TypeAD/DC Power
  • StyleEnclosed
  • Output ChannelSingle
  • AC input range selectable by switch
  • Protections: Short circuit / Overload / Over voltage/Over temperature
  • Forced air cooling by built-in DC fan
  • Withstand 300vac surge input for 5 second
  • Built-in cooling Fan ON-OFF control
  • Built-in constant current limiting circuit
  • 100% full load burn-in test
  • LED indicator for power on
  • Fixed switching frequency at 90KHz
  • Low cost, high reliability
