The Vicor MicroRAM URAM3C21 is an output ripple attenuator module that combines active and passive filtering to achieve significant noise attenuation. 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 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 URAM3C21 is compatible with various switching converters, including Vicor's VI-200, VI-J00, and Maxi, Mini, and Micro series DC-DC converters, making it a versatile solution for power system design.
This specific variant features a long pin style and a slotted baseplate for mounting.
