The BN-45I is a 4.5-digit dimmable voltmeter with power supply options of 5VDC (isolated, standard), 9-36 VDC, or 36-75 VDC (both auto-sensing and isolated, optional) for your 5V, 12V, 24V, and 48VDC applications. It is in a compact 96x24mm case that has a short depth of just 2.83 inches (72mm) behind the panel.
The meter has three common input ranges of 2V (standard), 20V, or 200VDC (both optional), and an optional factory-installed 1200VDC range. Other ranges and special scaling can be ordered and calibrated at the factory (see Special Options & Custom Calibration tab below). Provision to offset the zero is also available as an option, including different offset ranges.
The display is shipped standard with red LEDs. Blue LEDs that are visible under bright sunlight, and green LEDs are also offered. Display Test, Dim/Blank, and Hold Reading are standard features.
Another version of the BN-45I, the model BN-45, is also available with a non-isolated 5VDC power supply.
