Newport 301AN Low-Cost 3-1/2 Digit AC Power Line Monitor with
"INFINITY STYLE BEZEL AND ADAPTER"
Model 301AN-AC is a low-cost, compact 3 1/2 digit panel meter for AC power line monitoring. Power and Signal Pinout Compatible with Model 2001A, includes "INFINITY STYLE BEZEL AND ADAPTER". It uses a half-wave rectifier calibrated to read the RMS value of sinusoidal signals.
Two input ranges are jumper- selectable: 50.0 to 199.9 Vac with 100 mV resolution and accuracy optimized for 115 Vac, and 50 to 650 V with 1 V resolution and accuracy optimized for 230 Vac. The meter fits a standard 1/8 DIN panel cutout 3.62" x 1.77" (92 x 45 mm) and requires a depth of less than 4.1" (104 mm) behind the panel. A screw-terminal barrier strip for signal and power is standard.
Features:
- 50.0 to 199.9 Vac Range (100 mV Resolution)
- 50 to 650 Vac range (1 V Resolution)
- Bright, 0.56 in (14.2 mm) LED display
- Automatic zero
- Display hold and test
- Screw-terminal barrier strip
- Short 4.1" (104 mm) Deep 1/8 DIN Case
Options:
- Isolated 9-32 Vdc power
- Isolated 26-56 Vdc power
