Key Document


The PMP30094 has been designed especially for E-meters. It uses the UCC28600 quasi-resonant flyback controller to provide two isolated outputs (5V @ 2A and 7V @ 0.3A) from an 3-phase input. The input voltage range is between 140VAC and 470VAC.

  • Wide AC input range (140VAC - 470 VAC)
  • 3-phase input
  • Excellent transient performance
  • Test report available
