Increased step load performance

Compared to analogue AVR’s, DEIF’s digital AVR handles larger load-steps within

the same frequency/voltage boundaries. Typically, the gensets will accept 10%

additional nominal load. The embedded help features increase performance.

The DVC 550 has no mechanical moving parts that regularly need replacement

meaning less downtime, less service cost and more effective regulation.

Fast backup for critical power applications

If connected to an  AGC-4 Mk II controller, the DVC 550 can (depending on how

fast the engine starts) synchronise multiple gensets within six seconds thanks to

DEIF’s unique close before excitation-feature (run-up synchronisation). 

Critical power applications, in particular, will benefit from the improved control,

increasing safety and allowing faster start-up.

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.

DVC 550 is a digital AVR designed for alternators with SHUNT, AREP or PMG excitation.

The voltage controller monitors and regulates the alternator output voltage.

Automatic voltage control

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 up to 277V AC

The controller includes several protections and functions to keep the alternator

running in full safe operation.

The DVC 550 controller can improve genset performance, delivering up to a 10%

increase of normal load impact capability and is suitable for any application in the

critical power, IPP and rental segments.

Optimise generator size

Due to high inrush currents during start-up, generators for electric motor starting

and transformer magnetisation are often oversized by up to 200%.

Featuring inductive motor starting and magnetisation boosting, DEIF’s DVC 550

reduces oversizing requirements to a minimum and thereby save capital cost.

Perfect solution for grid code compliance

The DVC 550 fast reaction speed complies with European grid codes, including German

VDE 4110/4105 standards. By combining the quick reaction speed with the AGC controller,

it is easy to comply with advanced grid codes (for example, low voltage ride through).

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.

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.
