The Vicor MicroRAM URAM2C22 is an output ripple attenuator module that combines active and passive filtering to achieve significant noise attenuation. It offers 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 URAM2C22 is compatible with various switching converters, including Vicor's VI-200/VI-J00 and Maxi, Mini, and Micro series. It features a threaded baseplate and long pin style for mounting.
Key specifications include an operating temperature range of -20°C to +100°C. The module is designed for applications requiring clean power delivery and improved signal integrity.
