[DEIF] DEIF Undervoltage and overvoltage relay type RMV-112D

2025-09-24

RMV-111D is a combined undervoltage and overvoltage relay in the "uni line" series of DEIF company, mainly used for the protection and control of generators. Through three-phase voltage detection, it achieves dual protection of undervoltage (U), and is equipped with functions such as timed tripping and fault status LED indication to ensure voltage stability of the power generation system.

[DEIF] DEIF PPU-3 Parallel and Protection Unit

2025-09-20

PPU-3 is a compact microprocessor control unit launched by DEIF, which integrates the protection and control functions of synchronous/asynchronous generators in an "integrated" design. It has a built-in galvanized separated three-phase measurement circuit and is designed for ship application scenarios. It supports two core working modes (which can be combined):
Stand alone operation: independent power supply control for a single generator;
Parallel with other generators: Multiple generators are synchronized in parallel to achieve load distribution and coordinated control.
Its core value lies in simplifying the generator control chain, which can be connected to the PLC control system through digital/analog I/O or serial communication, and has flexible functional expansion capabilities.
