Companion power supply board for the Modulus-86, Modulus-186, Modulus-286, and LM3886DR power amplifiers.



  • Optimized PCB layout.
  • Minimized output impedance and ground impedance through the elaborate use of planes and pours.
  • On-board, heat sinked bridge rectifier.
  • Supports two electrolytic capacitors of up to 40 mm in specified diameter (max. diameter: 41.5 mm).
  • Connector for ON-indicator LED.
  • Simple capacitor snubber to eliminate coupling of diode switching noise into sensitive circuits.
  • Molex MegaFit 23 A rated output connector compatible with the Modulus-286 and LM3886DR.
  • Terminal blocks capable of handling up to AWG 10 (5.2 mm2) wire sizes.
