| Main Characteristics | Small size facilitates installation and maintenance ofequipment. It
is designed specially for reactive local compensation ofthree-phase
transtormer with rated voltage 380V and capacity 30~600KVA.
Controlled by microcomputer and adopting automatic compensation
mode, ithas complete functions and reliable performance. LED
digital displayshows the power factor of power line, ranging from
lagging (0.00~0.99)to leadign(0.00~0.99).The set values of COS,
delay and over-voltage canbe set through three functional set keys
on the panel keyboard and shownon the digital display.Concise
man-machine dialogue facilitatestheoperation.With pilot lamp
indicating the lagging, leading to operate andover-voltage, LED
hints program input.With over-voltage protectionfunction, it is
safe in operation.(The over-voltage set value has beenset at 430V
in factory. The user can reset is between 400V and 450Vaccording to
their own needs.) When power line voltage exceeds the setvalue, COS
digital meter is changed automatically and shows the presentvoltage
value of power line. At the step by step. Once the voltageregains
normally, This installation will work automatically
again.Havingstrong anti jamming capability, it can resist
nterference pulse of 2000Vinput directly through power line. The
index exceeds national specialstandard. |
