URAM2H23 Description

Short technical summary and product information.

The Vicor MicroRAM URAM2H23 is an output ripple attenuation module that combines active and passive filtering techniques 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 URAM2H23 is compatible with various switching converters, including Vicor's VI-200/VI-J00 and Maxi, Mini, and Micro series DC-DC converters. It is available with long pin styles and a threaded baseplate for mounting.

Key specifications include an operating voltage of 3-30V DC, a current rating of 20A, and an operating temperature range of -20°C to +100°C. The module is designed for applications requiring high levels of output ripple attenuation.
