uRAM3HN3 - Output Ripple Attenuation Module

This page provides the datasheet information for the uRAM3HN3, a member of the URA Output Ripple Attenuation Module family.

Datasheet Summary

Description

The MicroRAM has an internal passive filter that effectively attenuates ripple in the 50kHz to 1MHz range.

An active filter provides attenuation from low frequency up to the 1MHz range.

The user must set the headroom voltage of the active block with the external RHR resistor to optimize performance.

Features

  • >40dB ripple attenuation from 60Hz to 1MHz.
  • Integrated OR’ing diode supports N+1 redundancy.
  • Significantly improves load transient response.
  • Efficiency up to 98%.
  • User selectable performance optimization.
  • Combined active and passive filtering.
  • 3-30Vdc input range.
  • 20 and 30 Ampere ratings Data Sheet MicroRAM TM Output Ripple Attenuation Module Patents Pending Shown actual size: 2.28 x 1.45 x 0.5 in 57,9 x 36,8 x 12,7 m.
