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.

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.
