Product source ↗The NS-28SW is a compact switching supply for powering radio equipment. It provides either a fixed 13.8 V output or an adjustable voltage from 9 to 15 V. A backlit analog meter switches between voltage and current indication.
Nissei distinguishes a continuous 20 A rating from a 28 A maximum output. Noise-offset adjustment shifts potential switching interference away from a troublesome receiving frequency. Rear output terminals, a cooling fan and a fuse complement the front-panel controls.
Features & equipment
- Fixed or variable output voltage.
- Noise-offset adjustment for switching interference.
- Backlit switchable voltage/current meter.
- Overload and short-circuit protection.
