speciﬁcally designed for high-voltage or high-frequency operation. The DMS-20PC-2-LM’s

unique power-supply circuitry allows a single model to

operate from either 240 to 310Vac with 50/60Hz inputs or

from 85 to 140Vac with 400Hz inputs. The meter requires

no external components or auxiliary power for full opera-

tion! Its large, 0.37"/9.4mm, bright red LED display is

easily readable under virtually all lighting conditions.

averaging (rms calibrated) to achieve a display resolu-

tion of 1Vac over its full operating range. Packaged in

a red-ﬁlter case with a built-in bezel, the meter is epoxy

encapsulated for ruggedness.

ter is ideal for use in emergency power equipment,

277Vac ﬂuorescent lighting systems, 400Hz aircraft

installations, and any other application requiring

accurate, high-voltage or high-frequency, ac line

monitoring.
