The Vicor MicroRAM URAM2HN3 is an output ripple attenuator module designed to combine active and passive filtering for noise attenuation. It achieves greater than 40dB of noise attenuation from 60Hz to 1MHz.
This module operates over a wide input voltage range of 3 to 30V DC and is available in a 20A model. 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 URAM2HN3 is compatible with most manufacturers' switching converters, including Vicor's VI-200/VI-J00 and Maxi, Mini, and Micro series DC-DC converters. It features a long pin style and a slotted baseplate for mounting.
Key specifications include a 20A power rating and an operating temperature range of -20°C to +100°C. The module's RoHS status is listed as Non-compliant, and its Moisture Sensitivity Level (MSL) is 1 Unlimited.
