The Vicor MicroRAM URAM2CG1 is an output ripple attenuator module that combines active and passive filtering to achieve significant noise reduction. It provides greater than 40dB of noise attenuation across a frequency range of 60Hz to 1MHz.
This module operates over a wide input voltage range of 3 to 30V DC and is rated for 20A. Its closed-loop architecture enhances load-transient response through dual-mode control, ensuring precise point-of-load voltage regulation. The integrated ORing diode function supports redundant and parallel operation.
The URAM2CG1 is compatible with various switching converters, including Vicor's VI-200/VI-J00 and Maxi, Mini, and Micro series. It is available in configurations with different pin styles and baseplate options, such as short or long pins with threaded or slotted baseplates, and through-hole mounting.
This module is suitable for applications requiring clean power delivery and improved signal integrity. Its design facilitates integration into power systems where noise suppression is critical.
