DEIF MTR-3 Multi-sensor

Achieve Precision with Automatic Voltage Control

The DVC 550 Digital Voltage Controller is designed to provide precise automatic voltage

control for alternators with SHUNT, AREP, or PMG excitation. This advanced controller

monitors and regulates the alternator output, ensuring stable and reliable performance.

With rated field current up to 7 A and up to 277V AC, the DVC 550 includes several

protections and functions to keep your alternator running safely and efficiently.

Optimize Your Power Systems with DEIF's DVC 550

DEIF's DVC 550 controller can significantly improve genset performance, delivering up

to a 10% increase in normal load impact capability. Suitable for critical power, IPP,

and rental segments, this digital AVR handles larger load-steps within the same

frequency/voltage boundaries compared to analogue AVRs.The embedded help

features enhance performance, reducing downtime and service costs.

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.

Compact size reduces space requirements

The iE 650 PLC is a compact controller that reduces space requirements in your control cabinets.

With a rack height of just 122 mm, it fits the de facto PLC standard, and the depth is only

114 mm (130 mm with connectors). The I/O modules of the iE 650 PLC are also high-density,

reducing the required cabinet backplane footprint to 1.2 cm2 per digital I/O channel.
