描述 Description

DATEL's DMS-20PC-2-LM is a component-size, self-contained, low-cost ac voltmeter specifi cally 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 operation! Its large, 0.37/9.4mm, bright red LED display is easily readable under virtually all lighting conditions. DMS-20PC-2-LM employs half-wave sinusoidal averaging (rms calibrated) to achieve a display resolution of 1Vac over its full operating range. Packaged in a red-fi lter case with a built-in bezel, the meter is epoxy encapsulated for ruggedness. This low-cost, extremely versatile digital voltmeter is ideal for use in emergency power equipment, 277Vac fl uorescent lighting systems, 400Hz aircraft installations, and any other application requiring accurate, high-voltage or high-frequency, ac line monitoring.
