DATEL's DMS-20PC-1-LM is a component-size, self-contained, low-cost
ac voltmeter for true line measurements. It requires no additional components
or auxiliary power. Simply plug it into any wall outlet and instantly read
voltages from 85 to 264Vac (47-63Hz). The large (0.37"/9.4mm), bright red
LED display makes the DMS-20PC-1-LM easily readable under any lighting
conditions.
DMS-20PC-1-LM employs half-wave sinusoidal
averaging (rms calibrated) and has a
display resolution of 1Vac over its full input

range. Packaged in a red-filter case with
built-in bezel, the meter is fully encapsu-
lated for ruggedness. All units are overvolt-
age
protected to 300Vac.
This low-cost meter is ideal for industrial,
