SHARMAN MULTICOM SM-30II 30 AMP Switch Mode Power Supply UnitIncludes noise offset control to eliminate the pulse noise of the switching circuit. This patent pending function is specially designed for communication equipment use. Its effectiveness may vary depending on the frequency and mode.Key Features/Specifications:Input Voltage: 220VACOutput Voltage: 9-15Vadjustable Output Voltage regulation: less than 2% Output current: 30A Meter: Displays the supply voltage and currentCigarette plug terminal: 10A (max)Fuse: 5A Protection: Short circuit and automatic current limiting over 30ADimensions:170mm (W) X 120mm (H) X 230mm (L)Weight: 2.5kg Review: Seems to be well made and erforms well. - I am very pleased with this power supply unit. It works well and has a cigarette lighter plug for up to 10 amps and two more connections for small devices on the front panel. The display is clear. The main power pack has variable voltage but can be set for 13.8 which is how I prefer to run it. It will easily cope with 100 watts from my radio and I have not found anything I don't like about this product. Review: Good steady well filtered switched mode supply - A significant risk with Switched mode power supplies is spurious noise that can wipe out the HF bands. None of that with this device, particular care has been taken to ensure a clean output _and_ a well shielded box. The noise offset adjustment has been added in recognition of this risk (so you can move any generated noise off your operating frequency), but I have found no need for it since it does not create any noise. Quiet operation, I have not had the fan engage yet but I generally use it only up to 15 amps. Perfect for all radio sensitive applications.
