Low Tech Meters For DCC Systems

Published:2013/6/21 2:40:00 Author:muriel | Keyword: Low Tech Meters, DCC Systems | From:SeekIC

These are inexpensive low tech methods for measuring voltages and currents in DCC track systems. They are not as accurate as a high frequency AC volt and amp meters but if you only need an approximate indication these circuits will do the job. The 1N5819 and 1N5820 diodes used here are Schottky types. This type of diode have a lower forward voltage drop (0.3V vs. 0.7V) than typical silicon diodes such as the 1N4000 series and can operate at efficiently at high frequencies.
