Power Factor Controller - PFR-1

GENERAL

it is used to work with a fixed load or for local compensation. Especially can be used for submersible pump compensation. Does not occupy a place within the panel, it is economical and it is very easy to use.The power value of the 1st step capacitor has to be the smallest between others.

QC1 < QC2 < QC3
ADJUSTMENT

C/k : (0,05 – 2)
C: Power of first capacitor.
k : Current transformer ratio.

Example

If C: 1 KVAR and k: 50/5 A In this case; k=50/5 = 10 and C/k= 1/10= 0,1
Adjust C/k to 0,1

Target Cosϕ : (0,70 – 1,00)
Ton : (1 – 100 s) Switch on time.
Toff : (1 – 100 s) Switch off time.

Installation Instruction

■ Read the user instructions and caution before installation.
■ Be sure that the panel you are installing in when power off.
