FAQ
Is it possible to lock the voltage at 13.8V?
Yes, a dedicated switch allows you to toggle between the adjustable mode (9-15V) and the fixed mode locked at 13.8V to avoid any false manipulation.
Does the fan run continuously?
No, the fan is thermoregulated, it only comes on when the load or internal temperature requires it, guaranteeing silent operation at rest.
Do the front-panel sockets support 30A?
Anderson-type connectors on the front panel are designed to withstand high currents, but for prolonged use at 28A/30A, we recommend using the screw terminal blocks on the rear.
Is the power supply protected against reverse polarity?
It incorporates short-circuit, overload and overvoltage protection to protect your radio equipment.
Can it be used in the USA or Japan?
Yes, thanks to its input voltage selector located inside or at the rear, it can operate on 110V AC.
Why choose the Nissei NS-2230D?
- Proven reliability from one of the world leaders in radio power supplies.
- Best-in-class compactness/power ratio for a clean station.
- Native integration of Anderson sockets, now a standard among radio amateurs.
- A clear digital display that replaces older, less accurate needle galvanometers.
