DMU-30ACV Series
Ruggedized True-rms ac Voltmeters with Daylight
Readable, Auto-Dimming LED Displays
Murata Power Solutions’ DMU-30ACV series of daylight-readable ac voltmeters mea-
sure 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.
DMU-30ACV series rms voltmeters are available in a choice of three input ranges:
20Vac (with 0.01V resolution); 200Vac (0.1V resolution); and 300Vac (1V resolution).
Because the input circuitry is electrically isolated from the unit’s operating power source,
these voltmeters can measure ac signals down to zero volts. An input frequency range
of 47-1kHz makes these voltmeters ideal for all ac voltage monitoring applications. And,
unlike conventional average-responding designs, these meters can measure and accurately
display the true-rms value of triangle waves, square waves, or any other irregularly shaped
waveform, with 0.4% full-scale accuracy.
DMU-30ACV series’ miniature size and ruggedized package is perfect for all industrial
and high-reliability instrumentation, alternative power generators, and any other application
which requires precise ac line monitoring in harsh indoor/outdoor environments. Simply
connect the input signal and an 85-264Vac source of operating power to the two rear-
mounted terminal blocks and the unit is fully operational.
TECHNICAL NOTES
IMPORTANT! To ensure safe and reliable operation, DMU-30ACV ac voltmeters must
be installed and serviced by quali?ed technical personnel. Contact Murata Power
Solutions / DATEL if there is any doubt regarding installation and/or operation.
1. Measurement Type: DMU-30ACV series ac voltmeters employ a precision rms-to-dc con-
verter and a stable voltage reference to measure and display the rms value of complex ac
waveforms. Crest factors as high as 5 produce minimal additional errors (see Perfor-
mance Speci?cations).
2. Wiring: All ac supply and input signal wiring must be adequately rated for the voltages

and currents they will carry, and must comply with any code or application-mandated
requirements pertaining to the user’s speci?c installation.
3. Power Supply Polarity, Fusing, Wiring and Grounding: The power supply inputs (TB1-1
and TB1-2) on DMU-30ACV voltmeters are not polarity sensitive, that is, they have no “AC
LO” or “AC HI” designations. These units do not include or require a connection to earth/

Wires speci?ed in the Functional Speci?cations section must be used for making connec-
tions to DMU-30ACV series voltmeters. All power-supply and load wiring must be rated
for the supply voltages and currents they will conduct and must comply with any code or
application-mandated requirements pertaining to the user’s speci?c installation.

Power Source
Input Signal
DMU-30ACV voltmeters are not internally fused. Terminal block TB1 is to be used only
Figure 1. DMU-30ACV wiring diagram
for powering the power meter’s internal circuitry; it must not be used to supply power
to external loads. The supply wires feeding these power meters must be fused with a
0.5A/250V time delay/time lag fuse, in accordance with applicable regulatory codes.
Wire insulation must be stripped to within ±10% of the stated dimensions, and wires
should be inserted into TB1 such that their insulation is not pinched by the screw terminal.
