Decsription:

* This product is an automatic power factor controller for three phase to control the closing amount of power condenser automatically.

* Following purposes can be achieved with this product.

1) Electricity charges can be saved by power factor discount.

2) Labor saving by work reduction of power factor monitoring and adjustment.

3) Effective use of facility capacity can be realized by power loss reduction.

4) Equipment life can be extended by stabilizing circuit voltage.

Features:

1) Small-sized and light-weight (DIN 144X144).

2) Either PFQ-3 for three circuits or PFQ-6 for 6 circuits can be selected according to condenser control no.

3) This product can be used for unbalanced load and balanced load of three phase 3 wire circuit, three phase 4 wire circuit (changeover by front switch).

4) AC110V, AC110/ √3V, AC220V (free input).

5) 2 types of control systems: PF control/ var control.

6) Overprogress of power factor at light load is prevented by light load shutdown function.

7) Condenser can be shut down by external signal with externally forced shutdown function.

8) Control system can be selected according to purpose.

a. Cyclic control

b. Optimal control

c. Multi step control
