Switchboard Instruments
AB/DB

AB/DB40-METAL CASE 
The industry standard for 4 1/4” switchboard instruments. Features include weather tight construction, and interchangeable scales.

AB/DB16-8 3/4” CASE 
This instrument is easily readable from distances over 30 feet. Available in the same ratings as the AB/DB40.

AB/DB17-ILLUMINATED 
An internally illuminated meter primarily used in high-vibration applications such as railroad and off-road vehicles. Available in Ammeter and Voltmeter configurations.

AB/DB14-HIGH SHOCK 
AB/DB14 Ammeters and Voltmeters are supplied in accordance with military specifications MIL-S-901 and MIL-M-16034. Primary application is for high shock conditions such as shipboard control panels.

AB/DB40-PLASTIC CASE 
Low-cost plastic case Ammeters and Voltmeters that meet ANSI C39.1. These meters offer the same high quality and reliability as the AB/DB40 at a substantial price difference.

2180-MINIATURE CASE 
Type 2180 switchboard instruments offer 250° scale resolution and 1.5% full scale accuracy. The 3 1/4” face takes up less panel space than conventional switchboard meters.

180-EDGEWISE 
Type 180 meters are available in horizontal and vertical mounting configurations. Internal illumination is available as an option.

DUAL-VUE METERS 
The Dual-Vue series of switchboard meters accepts inputs of AC or DC voltage or current. They provide a convenient combination of an analog scale and digital readout in a rugged switchboard meter case with IP54 rated cover.
