Adopt AC sampling technology
Digital integration, filtration, not sensitive to the
harmonywave.Regard the reactive power as controlling physical
quantity; it hashigh control
precision, without input and cutoff shaking.The operation of the
fulldigital of control parameter, easy to use, put in right place
in onestep, and the data are not lost to have a power failure.Adopt
andoptimize the excellent control scheme automatically, reduce the
times ofinput and cutoff, improve the service life of
system.Stronganti-interference ability can resist 2000V
interference pulse from powerdirect, and not crashing, does not
lose the data, it is reliable to runsteady.Digital display electric
network power factors, reactive power,voltage, current (primary
side) and control parameter.With two workingmodes of manual and
automatic is convenient for user to install anddebug.With the
function of over-voltage, under-voltage judgment anddisplay and
fast cutoff capacitor group, prevent capacitor group fromrunning
under the over-voltage condition.With the function of
availableinput and cutoff shocking and locking(please inbdicate
while orderinggoods).With the function for the delay time of the
selectable singlegroup capacitor for 200 seconds from cutoff to
input, malkes capacitorhave abundant discharging time after cutoff
and reduce capacitor theimpact in electric net when oputting into
again (Please indicate whileordering goods).
The input resistance of current sampling signal is smaller than
0.05;itcan be taken out from measuring loops directly.Output Loops
1-12 Loop |
