Why Choose the Lovato PMVF30D048 Interface Protection System?

The Lovato PMVF30D048 is an advanced interface protection system unit designed for electricity generation installations connected to medium-voltage distribution networks. Compliant with the Italian CEI 0-16 standard, it continuously monitors electrical network conditions and controls the interface device when voltage or frequency values move outside the permitted operating limits.

The PMVF30D048 provides dual-threshold minimum and maximum voltage protection together with dual-threshold minimum and maximum frequency monitoring. Measurements can be taken through external voltage transformers in medium-voltage systems or directly in compatible low-voltage installations, providing flexibility across renewable energy, cogeneration and distributed generation projects.

Featuring a 12–48 V DC auxiliary supply, two relay outputs and compatibility with external current transformers featuring 1 A or 5 A secondary outputs, the PMVF30D048 is suitable for integration into professional grid protection panels. Its compact 96 × 96 mm panel-mounted format provides clear system information while helping engineers configure and supervise interface protection functions reliably.

Key Advantages

  • Dedicated interface protection system for medium-voltage applications.
  • Compliant with the Italian CEI 0-16 grid connection standard.

  • True RMS electrical measurement.
  • Graphical display for programming and system supervision.
  • Panel-mounted construction for protection switchboards.

Reliable Medium-Voltage Grid Interface Protection

Electricity generation systems operating in parallel with a public distribution network must be disconnected when voltage or frequency conditions exceed permitted limits. The Lovato PMVF30D048 continuously supervises the grid connection and operates the external interface device when an abnormal electrical condition is detected.

Its configurable protection thresholds allow the disconnection response to be coordinated with the requirements of the generation installation and distribution network. The 12–48 V DC auxiliary supply is particularly useful in panels equipped with dedicated DC control supplies or battery-backed protection circuits.

Typical Applications

  • Medium-voltage photovoltaic installations.
  • Cogeneration and combined heat and power systems.
  • Distributed electricity generation plants.
  • Industrial generation systems connected to the grid.
  • Wind and renewable energy installations.
  • Grid interface protection panels.
  • Parallel generator connections.
  • Utility and energy monitoring systems.
