D510 C
Digital voltage regulator

1.2 - Characteristics
The different functions of the D510C are:
- Voltage regulation
- Regulation of the power factor (PF)
- Regulation of the reactive power
- Manual regulation (Iexc)
•
Voltage regulation:
The D510C regulates
the alternator output voltage. Regulation is
applied to the mean value or the true rms
value (TRMS).
•
Regulation of the power factor:
The
D510C regulates the power factor. This is
the ratio between the active power
(P = √3*U*I*cos φ) and the apparent power
(S = √3*U*I).
-
Inductive P.F. [0; π/2]
means that the
current is lagging behind the voltage. The
load is inductive (induction motor,
transformer, etc).
-
Capacitive P.F. [π/2; π]
means that the
current is leading the voltage. The load is
capacitive (fluorescent lighting, etc).
•
Regulation of the reactive power:
The D510C regulates the reactive power
(Q = √3*U*I*sin φ) at a fixed value.
•
Manual regulation:
The D510C can
regulate the excitation current.
These functions are selected when setting
the AVR parameters.
