The Nissei NS-1228A is a professional-grade, highly reliable switching power supply engineered to deliver continuous, stable power to electronic equipment and two-way radio stations. Providing a continuous output of 25 Amps at 13.8 VDC and a peak current capability of 28 Amps, this unit handles high surge demands with ease while maintaining outstanding electrical performance.<\/p>\n
This advanced power supply features an adjustable output voltage ranging from 9 to 15 VDC, allowing complete precision matching for your delicate workshop instruments or transceivers. Designed to safeguard communication clarity, it operates with an exceptionally low peak-to-peak ripple and noise level of less than 0.3%, preventing typical RF hums or interference issues.<\/p>\n
Built to endure tough environments, the NS-1228A is housed in a rugged metal casing with a protective powder coating. It includes comprehensive safety features such as automatic short-circuit, overvoltage (triggered at 16V), and overload protection, along with external fuse access for rapid maintenance. Additionally, its front panel is equipped with customizable LED backlighting options (blue, vintage yellow, or white) to perfectly blend with your operational station layout.<\/p>\n
