Description
NS-30SD: New line of NISSEI switching power supplies with digital instrument that simultaneously displays both the output voltage and current draw, designed specifically for use with transceiver equipment for amateur radio operators wishing to have a power supply at the station, clean from the point of spectral view and with low ripple. All models are protected by a short-circuit, with limitation of the maximum current and voltage (up to 16Vdc ± 0.5V). The NOISE adjustment is located on the front panel and is carried out by means of a circuit that shifts the switching frequency to bring it, in case of interference, out of any admitted amateur radio band..
