Yokogawa AB/DB Switchboard Instruments
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.
| Accuracy: | ±1.0% of full scale basic accuracy class. Specific accuracies: Rectifier type meter- ±1.5% @ 25˚C calibrated to sine wave. Expanded Scale Voltmeter- 0.3% of mid-scale. Power factor meter- ±1% of scale length from 20-100% of rated current on balanced system models; ±3% of scale length on unbalanced system model types. Synchroscope- ±1% of scale length. Frequency meters- ± .15Hz @45-55Hz and 55-65Hz, ±0.093Hz @ 58-62Hz, ±1.5Hz @350-450Hz. |
