Lovato PMVF30D048 interface protection system compliant with CEI 0-16 for medium-voltage generation installations, featuring dual-threshold voltage and frequency protection and a 12 to 48 V DC auxiliary supply.
£3,954.64
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.
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.

The PMVF30D048 monitors voltage and frequency at the connection between a local electricity generation system and a medium-voltage distribution network. It controls the external interface device when abnormal grid conditions are detected.
The unit operates from a 12–48 V DC auxiliary supply, making it suitable for protection panels with dedicated low-voltage DC control power.
The Lovato PMVF30D048 is designed to comply with the Italian CEI 0-16 standard for interface protection in medium-voltage systems.
Medium-voltage measurements are obtained through external voltage transformers. Compatible low-voltage systems can be measured directly by the interface protection unit.
The unit supports external current transformers with either 1 A or 5 A secondary outputs.
Lovato PMVF interface protection systems are used by renewable energy specialists, electrical engineers and panel builders to provide reliable grid supervision and disconnection control for medium-voltage generation installations.
