Power Controller (JKWF12)

JKWF series controller regards 8 single chip microcomputer as core, adopt

the control scheme of phase splitting sampling and compensation and common compensation and plase splitting compensated together, very suitable fro reactive compensation with 50HZ 0.4kv three phase load imbalance power system

1. Function characteristic

A. LED display three phase voltage, current, active power, reactive power, current power, power factor, and electric net frequency and controll data and so on (using this controller in the capacitor bank and compensation equipment, so you would not assemble current meter and voltage meter and universal switch in the capacitor bank )

B. It have anti interference ablility, it can resisted directly input 2000V impulse. It still work, and it would not stop suddently, and keep before data, C. It is reactive power, control accuracy is very high

D. User can remend the control data according themselves data, power is off, the data keep

E. It has auto discriminating phase function, (fetch signing will keep same state )

F. Current sampling sign input resistance is less than 0.5Ω, it can be taken out from measuring loops directly

G. It have over voltage, under voltage and lack phase protection function

H. Compensation mode: Every phase compensation, everyphase and three phase compensation, three phase compensation

I. Output way: Staic state, dynamic state, compound etc

Output step: 1-12 step

2. Technology data

A. Basic data

Rated voltage: AC 220V 10%, rated current AC 0-5A, rated frequency: 50Hz 5%

B. Controlled data

Sensitivity: 100mA

COSφpreset: 0.80-0.99, step length 0.01, factory preset 0.98

Put and switch delay: Dynamic stat 100ms-30S, static 1-250S, factor seting dynamic 5S, static 30S

Over voltage protection: 230-260V, step length 1V, return diffirent 6V, factory setting 240V

Under voltage protection 180V return diffirent 6V

Auto discriminating phase: ON/OFF, factory setting ON

Reactive limited OFF-4-100kvar, factory setting OFF

CT variation: 50/5A -3000/5A, step length1, factory setting 500/5A

Capacitor capacity 0-99kva every step factor setting 10KVAR

Contactor capacity dynamic state output 12V*50mA every DC

Static state output 380v*7A 200V*5A

Testing accurancy

Voltage 0.5%, current 0.5%, power factor 1.0%, Active power 1.0% reactive power 1.0%

Size 113*113
