Frequently Asked Questions

How do I choose the right UPS for my application?

The right choice of UPS depends on:

  • Total load (kW/kVA)
  • Type of cargo (IT, motors, electronics)
  • Desired backup time
  • Single-phase or three-phase (1-phase / 3-phase)
  • Requirements for redundancy and availability

Freber assists with dimensioning based on actual load profiles and operating scenarios, ensuring that the solution provides sufficient safety margins and optimal service life.

What is the difference between Line-Interactive and On-line (VFI) UPS?

Line-Interactive UPS is suitable for less critical applications and provides voltage stabilization for minor deviations.

On-line (VFI – Voltage and Frequency Independent) provides continuous double conversion and full isolation from mains disturbances, and is recommended where power outages or voltage deviations are unacceptable.

For industrial and critical installations, online solutions are generally recommended.

When should you choose a 3-phase UPS over a 1-phase UPS?

Single-phase UPS systems are typically used for IT equipment, smaller installations, and control systems.

3-phase UPS is used when:

  • The power requirement is higher
  • The load is three-phase
  • The installation is industrial
  • Operational reliability and scalability are critical

Freber assists with correct phase selection and load balancing.

How is the necessary battery capacity and backup time determined?

Backup time is determined by:

  • Power consumption of the load
  • Desired autonomy time
  • Battery type and configuration

We calculate the necessary battery pack based on the desired operating time and can supply both standard battery modules and customized solutions – including monitoring systems (PBAT) and external bypass solutions.

What distinguishes Freber from a pure UPS dealer?

We don't just deliver a UPS unit, we deliver a customized solution.

Freber assists with:

  • Technical advice and dimensioning
  • Integration with battery systems and energy storage
  • Adaptation to rack, cabinet, or freestanding installations
  • Choice of bypass, monitoring, and accessories

The goal is stable operation and predictable availability, even in demanding and critical applications.
