Murata have announced the release of the third generation of the DMR20 series of round, miniature digital panel frequency monitors. Designed to measure and display AC mains frequencies in the range of 45 to 65 Hertz, over an input voltage of 85 to 264 VAC, the monitor is suitable for mounting in an industry-standard “oiltight” 30 and 30.5 mm / 1.2 inch round panel cutout.
The new DMR20-1-FM-R-C is the world’s smallest, self-powered, ac line frequency monitor. Simply connect 85 to 264Vac (45-65Hz) power and the meter is fully operational—no additional components are required. The unit can also measure distorted 120Vrms power sources with triangle and square waveforms, as well as quasi sine wave outputs of dc to ac power inverters.
Murata Power Solutions have an extensive range of competitively priced Radial leaded inductors that are ideal for power and EMI filtering applications.
