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.
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.
IMPORTANT! To ensure safe and reliable operation, DMU-30ACV ac voltmeters must
be installed and serviced by qualifi ed technical personnel. Contact Murata Power
Solutions / DATEL if there is any doubt regarding installation and/or operation.

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/
chassis ground. Refer to Figure 1 for a typical wiring diagram.
Wires specifi ed in the Functional Specifi 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 specifi c installation.
DMU-30ACV voltmeters are not internally fused. Terminal block TB1 is to be used only
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.
