Highlights:• Reduces noise from DC switch mode power supplies using Active Noise Cancellation (ANC)• Compatible with 5 V to 24 V DC power supplies up to 3.5 A / 84 W • Effective across an ultra-wide frequency range from 1 Hz to over 5 GHz • RFI-shielded aluminium enclosure • Supplied with adapters for multiple DC plug sizes • Reverse polarity adapter included Reduce noise from your power supply:DC iPurifier2 is designed to reduce electrical noise generated by DC switch mode power supplies, commonly used with DACs, network players, streamers, routers and other audio equipment. The unit is connected between the power supply and the device, where it uses iFi's Active Noise Cancellation (ANC) technology to actively suppress unwanted noise on the DC power line. According to the manufacturer, noise can be reduced by up to 100,000 times depending on the type of interference, helping to lower the overall noise floor and provide improved operating conditions for connected equipment.Its ultra-wideband design is effective from 1 Hz to over 5 GHz, enabling it to attenuate both low and high frequency noise. The enclosure is made from RFI-shielded aluminium, while the internal components include Panasonic SP-Cap polymer capacitors, precision MELF resistors and custom low-noise operational amplifiers. These components have been selected to provide efficient noise suppression together with stable electrical performance. The specifications and technologies described are based on the manufacturer's documentation. Easy integration into existing systems:DC iPurifier2 supports DC power supplies from 5 V to 24 V with a maximum load of 3.5 A or 84 W. It features a standard 5.5 x 2.1 mm DC connector and includes adapters for 5.5 x 2.5 mm and 3.5 x 1.35 mm connectors, making it compatible with a wide range of power supplies. A reverse polarity adapter is also included for equipment using a centre-negative DC connection.Specifications:• Active Noise Cancellation (ANC) for DC power supply noise reduction• Supports DC power supplies from 5 V to 24 V • Maximum load: 3.5 A / 84 W • Effective from 1 Hz to over 5 GHz • RFI-shielded aluminium enclosure • 5.5 x 2.1 mm DC connector • Adapters for 5.5 x 2.5 mm and 3.5 x 1.35 mm included • Reverse polarity adapter included • Panasonic SP-Cap polymer capacitors with low ESR • Precision MELF resistors • Custom low-noise operational amplifiers • Copper alloy EMI shielding
