Detailed Product Description

48*48 Common AC digital Ammeters meter

AOB184I, AOB185I  series digital display ammeters are a sort of economic digital instruments, which are mainly used in the real -time measurement and indication on AC or DC of electric wiring. It can assort with all kinds of electrical quantity and non-electrical quantity transmitter with linearity analog signal output and indicate the electrical quantity or non-electrical quantity value in the primary circuit. With features of high precision, good stability, direct reading, strong anti-interference ability, it can be used extensively in all voltage classes of substation of city and countryside, power station, transformation and distribution room of public institution/enterprise units, and many fields of intelligent building/subdistrict, metallurgy, petrochemical, airport, railway, port, hospital, school, municipal, etc. It is an idea upgraded product of original dial instrument.

Technical feature
The greatest feature is as following: It is added several specific pins for switching measuring range to the common digital display ammeter wiring. Though adjusting the quantity and position of shorting jumper on the pin, the full range indicated value of the instrument changes with a special rule when inputting the rating signal. So it achieves the goal that the odd instrument can adapt the instrument transformer (or electrical shunt) many different specifications and raises the cost performance and flexibility of instrument usage.
