Dehumidify and dry your genset with integrated ventilation functions

Condensation build-up during idle time is a common problem in tropical climates.

Use the genset ventilation mode to prevent condensation forming on the windings

by removing built-up humid air using the alternator fan. Power generation is postponed

until the humidity levels are safe. Condensation on the windings can be removed using

the genset drying mode. During drying mode heat generated from a controlled internal

circulating in the alternator winding is used to evaporate condensation on the windings.

The genset will be connected to the busbar when it is safe to do so.

Maximum control with an integrated genset controller solution

The DVC 550’s built-in J1939 based communication offers an exclusive communication

channel to DEIF’s advanced controllers. Providing a high number of alternator data for

display, broadcast or predictive maintenance, the J1939 built-in communication is unique

on the market. You can quickly swap between nominal voltage and or frequency setting

 for a generator. Using CAN bus-based communication for voltage regulation reduces

the potential number of failure sources.

Use the DVC 550 together with the AGC-4 Mk II controller to maximise your benefits.

Advanced Features of DVC 350 Digital Automatic Voltage Regulator

The DVC 350 Digital Automatic Voltage Regulator by DEIF is designed to provide superior

automatic voltage regulation for a wide range of alternators.

Whether your system uses SHUNT, AREP, or PMG excitation, the DVC 350 ensures optimal

performance and reliability. With its advanced alternator protections and functions,

this digital AVR is a cost-effective solution for maintaining efficient and safe power systems.

Benefits of Automatic Voltage Regulation

Automatic voltage regulation is crucial for the stability and efficiency of power systems.

The DVC 350 AVR offers precise control and protection, minimizing the risk of voltage

fluctuations and ensuring consistent power supply. By integrating the DVC 350 into your system,

you can enhance the longevity and performance of your alternators, reducing maintenance costs and

downtime.

Ideally suited for volume production

The tried and tested DVC 350 delivers cost-effective performance and is particularly

well suited for volume production: DVC 350 setups can easily be copied from unit to

unit without setting switches or potentiometers manually. This greatly speeds up setup

operations and productivity, and it increases consistency and safety as the same setup

can rapidly be applied across any number of AVRs. Individual DVC 350s can also be

regulated using the built-in analogue potentiometer if needed.

For more advanced alternator applications, we recommend the DVC 550 digital AVR.

Integration with the AGC 150 series

The DVC 350 is ideal for use with DEIF AGC 150 controllers which are able to control all

its built-in digital voltage regulation features and can receive fault information directly

over a CAN bus connection. Factory settings can easily be changed using the free,

user-friendly DEIF EasyReg Advanced PC utility software. The DVC 350 even offers a

Automatic Voltage Regulator

The DVC 350 is a digital automatic voltage regulator (AVR) for controlling alternators

 which require rated field currents up to 5 A. Designed for a wide range of alternators

with SHUNT, AREP (auxiliary winding), or PMG (permanent magnet) excitation,

the DVC 350 controls the alternator from the field current or the output voltage

regulation loops. It includes several protections and functions that keep the alternator

running efficiently and safely.

Wide range of regulation features

The DVC 350 offers several regulation features that satisfy most common control

requirements: reactive and line droop compensation, a soft start function,

voltage soft recovery, start on threshold, and a load acceptance module (LAM) function.

It enables regulation over a CAN bus connection, and it offers a wide range of protections

(over and under voltage, over and under frequency, over and under excitation,

and voltage unbalance). The unit is able to withstand sudden short-circuits for up to 10 seconds.

Benefits with AGC-4

Easy installation with CAN bus

A dedicated J1939 CAN bus connection provides efficient and

exclusive communication between the DVC and the controller.

This makes it possible to, for example, quickly and easily swap

between nominal voltage or frequency settings for a generator.

Avoid genset over-sizing

Use magnetisation boosting or inductive motor starting to limit

the stator current during start-up. This reduces the need to start

multiple gensets when connecting a heavy load, and reduces

genset over-sizing requirements to a minimum.

Protect the genset from humidity

Drying: Condensation on the windings can be removed using the

genset drying mode. During drying mode heat generated from a

controlled short circuit is used to evaporate condensation on the

windings. The genset cannot be connected to the busbar until it is

safe to do so.

Ventilation: Use the genset ventilation mode to prevent

condensation forming on the windings by removing built-up humid

air using the alternator fan. Power generation is postponed until

the humidity levels are safe.

Fast backup for critical power applications

Use run-up synchronisation to start multiple gensets at the same

time while the gensets are connected to the busbar.

Gridcode compliance

The DVC 550 fast reaction speed complies with European

gridcodes. By combining the fast reaction speed with the AGC

controller, it is easy to comply with advanced gridcodes, such as

VDE 4105 and VDE 4110.

General description

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
