The Vicor MicroRAM URAM2HN2 is an output ripple attenuator module that combines active and passive filtering techniques to achieve superior noise attenuation. It offers greater than 40dB of noise attenuation across the frequency range of 60Hz to 1MHz, making it suitable for applications requiring clean power.
This module operates over a wide input voltage range of 3 to 30V DC and is rated for 20A of current. Its closed-loop architecture enhances load-transient response and provides precise point-of-load voltage regulation. The integrated ORing diode function supports redundant and parallel operation, adding flexibility to power system designs.
The URAM2HN2 is compatible with various switching converters, including Vicor's VI-200/VI-J00 and Maxi, Mini, and Micro series. It is available with different pin styles and baseplate options to accommodate various mounting and integration requirements.
