FAQ

What is the primary function of the Stromag CFU 230/400V unit?

Its primary function is to act as a rectifier, converting the incoming AC voltage (either 230V or 400V) into a DC voltage suitable for energizing and controlling an electromagnetic industrial brake.

How do I select between the 230V and 400V input options?

Typically, voltage selection is made by connecting the AC supply to specific terminals inside the unit. It is crucial to consult the product’s wiring diagram to ensure the correct connections are made for your available supply voltage to prevent damage to the unit or the brake.

Is this unit a half-wave or full-wave rectifier, and what is the typical DC output voltage?

Units like this are often half-wave rectifiers. For a half-wave rectifier, the DC output voltage is approximately 0.45 times the AC input voltage (e.g., 230V AC input yields about 103V DC). For a full-wave rectifier, it would be about 0.90 times the AC input. The exact configuration should be verified based on the brake’s requirements.
