Switching Power Supply


▶ NS-28SW

CE / LVD

INTRODUCTION:

NS-28SW is an efficient,compact, and light-weighted switching power supply. It is designed to minimize the noise for the radio communication equipment. even when the noise occurs, it can be eliminated by the noise-offset control. Other convenient functions like voltage pre-set knob and a highly visible back-lit meter are all inculded in this standard power supply.
