- 3 Characteristics [Go to Page]
- 3.1 Input power factor [Go to Page]
- Power factor is dependent upon the current’s waveshape as well as the phase relationship between the current and voltage. The power factor is to be calculated by determining the ratio of the active power to the apparent power. The active power is to b...

- Note: Typical ballast factors (BF) fall into three ranges: low (BF ≤ 0.85), normal (0.85 < BF < 0.95), high (BF ≥ 0.95).
- Note: There is no ballast factor for UV-C lamp ballasts because the UV-C lamps do not produce visible light.
