Descrição

From Sep 1st 2018, DP3001 Series will be discontinued. As a possible substitute, please check out the DPPt Meter or DP20 Meter for details.

The DP3001 is a low-cost, true-differential 4-1/2 digit panel meter for applications that require high resolution and high accuracy DC measurement. It fits a standard 1/8 DIN panel cutout and requires a depth of less than 104 mm (4.1") behind the panel. Display span is ±19,999 counts. Accuracy is 99.98%.

INPUT RANGES
The DP3001 offers DC voltage ranges of ±1.9999, ±19.999 and ±199.99 Vdc. By using an external DC voltage reference, any of these ranges can be configured for 3-wire ratio measurement.

OPTIONS
The meter can be electrically configured for three input voltage ranges, four decimal-point positions, high-impedance 3-wire ratio input. Mechanical options include a screw-terminal barrier strip for signal and power and a splash-proof lens cover which meets NEMA 4 (IP65) requirements.
