DEIF RMQ-111D & RMQ-121D Loss of Excitation Relay/Over-excitation Relay

The RMP-112D is a protective overload and reverse power relay for

generator and prime mover protection.

Protection against overload is crucial in setups where the prime mover

is under-dimensioned in proportion to the AC generator.

The versatile unit features a number of adjustable parameters.

The MVR-V211 busbar protection relay offers voltage and frequency

protection and can operate as a synch-check relay (ASNI 25) for up

to three circuit breakers. With its powerful logics programming and

expandable communication and I/O it is ideal for compley load

shedding and ATS (Automatic Transfer Switch) applications.

The MVR-T256 transformer protection device is an easy-to-use differential

protection relay with high I/O capacity.

The MVR-T256 transformer protection device is an easy-to-use differential

protection relay providing overcurrent protection for both low-voltage and

high-voltage side of the transformer, earth fault protection, negative

sequence overcurrent protection as well as two independent instances of

restricted earth fault protection.

The I/O capacity can be customized to the applications needs by 10 available

extension slots.

10x Current input (configurable 0.2…10A)

3x Digital input

5x Output relay (4NO, 1CO)

1x IRF output (1CO)

2x Remote com port (1 x RJ45 Ethernet and 1 x RS-485)

- IEC 61850 Ed1 & Ed2. Modbus TCP/RTU, IEC 60870-5-104/103/101.

- DT, IEC or ANSI time/overcurrent curves with settable release delays

- 10 extension slots for additional hardware options

- Event recorder (up to 15 000 events)

- Disturbance recorder (up to 100 disturbance records)

- 2nd and 5th harmonic blocking.

- Automatic verification for the connection group and nominal value settings.

- Overloading and through fault statistics for preventive maintenance.

The DVC 550 is a digital automatic voltage regulator, which

monitors and regulates the alternator output with rated field

current up to 7 A and voltage supply up to 277 V AC.

It is designed for alternators with SHUNT, AREP (auxiliary

winding) or PMG (permanent magnet) excitation types.

The DVC adjusts the excitation current in the exciter field

according to the desired alternator output.

The DVC 550 includes several protections and functions to keep

the alternator running in full safe operation.

The utility software, DEIF EasyReg Advanced, provides a visual

interface to configure values and parameters. The intuitive

interface makes it fast and easy to monitor and troubleshoot.

EasyReg can also be configured directly with the USB port

without external power supply.

DEIF’s system utility software v.3 (USW-3) is a unique tool for engineers,

service personnel and end-users to configure and supervise one or several

interconnected genset controllers, available for free download from our

website.

The utility software is easy to install, the general purpose software works

off the-shelf using Ethernet or USB cable communication  to configure,

commission and supervise both single gensets and plants of up to 256

units.

The utility software tool is compatible with a range of DEIF controllers;

it adjusts easily to the capabilities of the connected devices and has been

designed with versatility in view.

The utility software, M-Logic, allows complex logic customisation with

configuration and evaluation of up to 40 logi expressions, including for

instance configuration of user level access, and features innovative pre

-installation configuration and emulation of plant design.

Incorporating extensive functionalities including overviews of alarms,

coolant temperatures, plant values, and fuel consumption, the utility

software, USW-3. is also an intuitive, easy-to-use tool for end-users to

operate on a day-today basis.

The DVC 350 is a cost-effective digital AVR that offers a wide range

of alternator protections and functions. Its digital setup options make

it ideally suited for volume production.
