• Power: It varies according to the type of
eld excitation (3 types).
-AREP:TheAVR is poweredby two auxiliary
windings which are independent of the
voltage sensing circuit.
The rst winding has a voltage in proportion
with that of the alternator and the second
has a voltage in proportion with the stator
current.
- PMG: A permanent magnet generator
(PMG) added to the alternator supplies the
AVR with voltage which is independent of
the main alternator winding.
- SHUNT: The AVR is powered by the main
winding (140 V – 50/60 Hz).
• Battery: This is used to supply the AVR
with between 12 V and 30 V. It must always
be present.
• Mains: This input is dedicated to the
phase-to-phase mains voltage which will be
taken as the reference when voltage
matching is performed.
• Alternator voltage: This sends the
alternator output voltage to the AVR in:
- three-phase (U, V, W)
- single-phase (V, W)
• Current transformer(s): This input
measures the current supplied by the
alternator. It must always be present when
the alternator is running in parallel
operation.
• The possible congurations are:
- 1 CT on phase U
- 3 CTs on phases U, V and W
• Temperature sensor(s): These are used
to measure the alternator temperature and
alert the user if there is a rise in temperature.
This measurement can be taken either with
1 PTC or 3 PT100s.
• Communication:
- USB port: This is used to connect the AVR
to a computer and creates the link between
the EasyReg software and the D500.
- CAN port: This is used to connect the AVR
to a computer and creates the link between
the EasyReg software and the D500.
The CAN link is only available in the
CAN version identied by the letter C
(eg: D510-C).
• I/O: This part is used to:
- Enter settings
- Send information from the D500
- Receive information from the alternator
• LEDs: These light-emitting diodes inform
theuserwhethertheAVRisworkingcorrectly
or not.

Characteristics1.2 ‑
The different functions of the D500 are:
- Voltage regulation
- Regulation of the power factor (PF)
- Regulation of the reactive power
- Manual regulation (Iexc)
• Voltage regulation: The D500 regulates
the alternator output voltage. Regulation is
applied to the mean value or the true rms
value (TRMS).
• Regulation of the power factor: The
D500 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 cos φ [0; π/2] means that the
current is lagging behind the voltage. The
load is inductive (induction motor,
transformer, etc).
- Capacitive cos φ [π/2; π] means that the
current is leading the voltage. The load is
capacitive (uorescent lighting, etc).
• Regulation of the reactive power:
The D500 regulates the reactive power
(Q = √3*U*I*sin φ) at a xed value.
• Manualregulation:TheD500canregulate
the voltage manually by altering the value of
the excitation current.
These functions are selected when setting
the AVR parameters.

HUMAN‑MACHINE INTERFACE2 ‑
The D500 human-machine interface
consists of 3 elements:
- The USB link
- The I/O
- The LEDs
Communication2.1 ‑
USB link
The EasyReg software and the D500
communicate via a USB cable (Universal
Serial Bus).
I/O2.2 ‑
This part of the board allows the operator to
use the inputs to make manual settings and
the outputs to check certain data or to
indicate whether certain AVR functions are
working correctly or not. An external power
supply (0 V – 10 V) is present which can
supply an external component (bulb, alarm,
etc).
The minimum input setting is 0% and the
maximum is 100%.
External setting is either:
- from an external potentiometer
- 4 - 20 mA
- 0 - 10 V
- ± 10 V
