Ruggedized True-rms ac Voltmeters with Daylight Readable, Auto-Dimming LED Displays

Murata Power Solutions’ DMU-30ACV series of daylight-readable ac voltmeters measure and display the true-rms values of complex ac waveforms. Their large 0.56” (14.2mm) high super-bright red LED-display is readable in full sunlight. An auto-dimming circuit automatically adjusts the display brightness for all viewing conditions.
And all DMU-30ACV ac voltmeters are packaged in a plastic package with an integrated bezel and gasket assembly designed to meet NEMA-4/IP65 for moisture resistance in outdoor applications.
