Yokogawa is a world leader in switchboard meters. As a global manufacturer of meter products for over 75 years, we are able to incorporate decades of experience into the design and development of the AB40 switchboard meter.
These internally illuminated switchboard meters are used primarily in railway locomotive applications for load and speed indication. They are suited to all applications where scale lighting and high accuracy is required. The wide radius pivot and jewel movement ensures accuracy and stability in the toughest environments. Standard lamps furnished with AB/DB17 are 2 GE #44 (6VDC) Lamps.
(16) The AB40 switchboard hour meter contains the time-proven 240 elapsed time meter in a 4.33" square weather-resistant case. It is designed for use with other switchboard instruments on electrical switchgear and control panels. It is UL/CSA recognized under file E 44857 and meets ANSI C39.1 specifications for shock and vibration. Accuracy of these AC hour meters matches the frequency control of the power system. Models are available with a time range of 0 to 99,999.9 hours in reset and non-reset configurations. The reset model requires the removal of the cover in order to perform the reset function.
These models of 4 1/4 switchboard meter are intended for use in areas of low ambient lighting and where night visibility of the meter scale must be maintained
