Ch Cos Φ (P) - Fronius SnapINverter Serviceanleitung

Ch Cos φ (P) Specification of the power factor cos φ depending on effective power P
The characteristic is defined by max. 4 characteristic points 0 - 1 - 2 - 3.
The coordinates must be entered for the characteristic points on the 0 (x) axis and on the
1 (y) axis.

Example:
Curve defined by 4 characteristic points
0: P = 15 %, cos φ = +0.85
1: P = 25 %, cos φ = 1
2: P = 45 %, cos φ = 1
3: P = 90 %, cos φ = -0.90
