The new shielding technology is the improved shielding technology. The power supply appliances are designed separately from the power supply. The external power supply is equipped with a shielding magnetic ring to completely isolate the AC electromagnetic wave from the DC power supply to ensure that the signal is not disturbed.Soft soft switch function soft soft start function to avoid the impact sound of "poof" when starting up.Stable filter current and stable voltage doubling rectifier filter circuit can effectively filter out the interference of AC signal.Two groups of balanced power supply, two groups of balanced power supply, balance the output signal, stabilize the voltage and suppress common mode interference.Phantom power supply and high-quality circuit can effectively prevent thousands of disturbances and eliminate whistling.Power supply interface: 48V phantom power supplyOutput interface: Standard balanced outputInput port: Standard balanced inputOutput voltage: DC48VPower consumption: less than or equal to 5WNoise: less than or equal to 18uvPlug Type: US Plug, it applies to Canada, India, Mexico, Thailand, Taiwan, the United States, the Philippines and so on.Colour: blackMaterial: metalSize: 26x20x6CMPackage Contents:1 * Phantom Power1 * US plugOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
