The Sharman 30A Linear Power Supply delivers a fixed 13.8V DC or a variable 5–15V DC output at 30A. As a linear design, it produces inherently lower noise than switch mode supplies — making it the preferred choice for sensitive HF receivers and high-power amateur radio transceivers where switching interference would be a concern. An LCD panel displays supply voltage and current in real time. A front-mounted cigarette socket provides a convenient 10A (max) auxiliary DC output. Short circuit protection and automatic current limiting above 30A safeguard both the supply and connected equipment. Fused at 5A on the mains side. At 9 kg and 300 × 150 × 240mm, this is a shack-grade supply built for permanent base station use — a step down in current from the 40A model but with a wider voltage adjustment range (5–15V vs 1.5–15V) and an LCD meter in place of analogue.
