Automatic Voltage Regulators (AVRs)
4243 en - 2012.10 / e
LEROY-SOMER
• Power: It varies according to the type of
eld excitation (3 types).
- AREP: The AVR is powered by 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).
10A fast fuses externally mounted
the D 510C must be used in the three
cases.
• Battery: This is used to supply the AVR
with between 11 V and 30 V. It must always
be present.
The battery supply must be
protected by a 1 A temporised fuse•
• Mains: This input is dedicated to the
measure phase-to-phase mains voltage
which will be taken as the reference when
voltage matching is performed.
• Alternator voltage: This input measures
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
or at PF or KVAR regulation or stator current
limitation.
• The possible congurations 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 D510.
- CAN port: This is used to connect the AVR
to a bus CAN interpreter in order to exchange
parameters with the D510.
The CAN link is only available in the
CAN version identied by the letter C
(eg: D510-C).
• I/O: This part is used to:
- Enter settings
- Send information from the D510
- Receive information from the alternator
• LEDs: These light-emitting diodes inform
the user whether the AVR is working
correctly or not.

LEROY-SOMER
1.2 ‑ Characteristics
The different functions of the D510 are:
- Voltage regulation
- Regulation of the power factor (PF)
- Regulation of the reactive power
- Manual regulation (Iexc)
• Voltage regulation: The D510 regulates
the alternator output voltage. Regulation is
applied to the mean value or the true rms
value (TRMS).
• Regulation of the power factor: The
D510 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 (uorescent lighting, etc).
• Regulation of the reactive power:
The D510 regulates the reactive power
(Q = √3*U*I*sin φ) at a xed value.
• Manual regulation: The D510 can
regulate the excitation current.
These functions are selected when setting
the AVR parameters.

2 ‑ HUMAN‑MACHINE INTERFACE
The D510 human-machine interface
consists of 3 elements:
- The USB link
- The I/O
- The LEDs
2.1 ‑ Communication
USB link
The EasyReg software and the D510
communicate via a USB cable (Universal
Serial Bus).
2.2 ‑ Analog I/O
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 voltage
(0 V – 10 V) is present which can be used as
a reference for an electronic device.
The minimum analogic input setting is 0%
and the maximum is 100%.
External by setting is either:
- from an external potentiometer (1k Ω),
- 4 - 20 mA,
- 0 - 10 V,
- ± 10V.
The two analog inputs can also be used to
achieve digital functions + / -.
NB : make sure that the voltage applied on
analogue input does not exceed 10V.
