The Nissei PS-30SWII 30 Amp Switch Mode Power Supply is designed for radio amateurs. It features a low-rogue switching circuit that mimics the performance of a linear power supply. It is compact, lightweight, and portable, weighing only 2.3 kg and measuring 190mm in width, 70mm in height, and 215mm in length. The power supply can continuously deliver up to 30 amps maximum current or 25 amps at 13.8V DC, with front-panel-advisable voltage ranging from 4-16Vdc.

Equipped with a Noise Control potentiometer, the PS30SWII Power Supply includes overload and short-circuit protection for added safety. It operates with an input voltage fixed at AC 220V 50Hz and offers an output voltage of 13.8V or a variable range of 9-15V. The output voltage regulation is less than 2%, ensuring stable power delivery. With a maximum ripple/noise of less than 80mVp-p, this power supply also features a cooling fan for efficient heat dissipation. Additionally, it comes with a single-volt/current meter display indicator and an F5A250V fuse for protection.
