Digital Power Meter - MDF

HOME > Power System > Power Meter > Digital Power Meter > Digital Power Meter for Industry > Digital Power Meter - MDF

Model MDF is specially designed of a very flexible DC versa meter for process systems, it features:

1.Wide DC input ranges of voltage span from + 400 V, current span from + 1 mA to + 200 mA.
2.Switchaable input ranges, selecting under the defined switching table & terminal connection.
3.Programmable of reading scale, following the simple fromulas & performming defined set switches: range from 0 to + 19999 counts.
4.Output option either of analog out put for per mv per count, or DC simulating power of 24V supply applied to two-wire system.
5.ASIC heart of conversion module much simplifying maintance process.
6.4-1/2 digits, high accuracy & fine resolution.
