The 1692 Switching Mode DC Power Supply provides high current output in a lightweight and compact package. It is suitable for a variety of uses, especially for powering DC operated mobile radio equipment on the bench. It provides a variable voltage output from 3V to 15V at 40A continuous operation. In addition a fixed 13.8 VDC output is also selectable by a slider switch. Switching mode power supplies have the advantage of lightweight and high efficiency when compared to traditional linear mode power supplies. The efficiency can exceed 80% under the best conditions. Advanced circuitry protects against overload and provides immunity from RFI. A bright red and green LED display provides for an accurate and highly readable indicator of settings.

  • Lightweight and compact
  • High efficiency
  • Current fold back circuitry with illuminated indicator prevents overloading the power supply
  • Over temperature protection circuitry
  • Over voltage protection prevents abnormal high output voltage
  • High RFI stability
  • Variable output 3V to 15V at 40A
 

This thing will supply 40 amps constant @ 3-15 volts. I have used it to power a mobile amp on my base station with ease.

    Hello gentlemen and Ladies. I have the dreaded RCI-2990 receive issue where my radio gets distorted when people get close to my location. I found the C90 Capacitor, but I can not for the life of me find the C89 capacitor. Can or does anyone have a picture of the exact location of C89 ? Thank you in advance, Wes
