Description
The operating principle is the same as in an online UPS. The rectifier converts the input voltage to direct current, and the inverter forms at the output a new sine wave with a frequency of 60 Hz from a 50 Hz mains or the other way round. The input has a cos φ of at least 0.99 and THDi below 1–3 %, so the converter does not distort the mains of the enterprise. At the output cos φ is 0.9–1.0, and for CF CUBE3+ the voltage distortion THDv is below 0.5 %. The CF CUBE3+ version covers 7.5–200 kVA. The CF CUBE4 is designed for 7.5–80 kVA and is built on a three-level scheme with a 4-core DSP processor.
How to choose
The conversion direction, 50/60 Hz or 60/50 Hz, is set for the specific equipment. The converter power is taken with the starting current of the load in mind, because motors consume several times more at start. For a load above 80 kVA only the CF CUBE3+ remains. If alternating voltage must be obtained from direct voltage, for example from a 48 V battery, the CS-IS inverters of 1000–20000 VA are suitable.

FAQ
Can the CF CUBE3+ convert 50 Hz to 60 Hz?
Yes, the converter works in the 50/60 Hz and 60/50 Hz directions.
What is the maximum power of the CF CUBE4?
The CF CUBE4 is made in 7.5–80 kVA, and the CF CUBE3+ in 7.5–200 kVA.
Does a static frequency converter distort the input mains?
The input cos φ is at least 0.99 and THDi is below 1–3 %, so the effect on the enterprise mains is minimal.
How does a static frequency converter differ from a motor frequency drive?
A static converter gives a stable sine wave of fixed frequency for all connected equipment. A motor drive changes the frequency to regulate the speed of one motor.
What is the output voltage quality of the CF CUBE3+?
An output cos φ of 0.9–1.0 and a distortion factor THDv below 0.5 %.
