I DESCRIPTION
I.1 OVERVIEW
DIAM4200 series CCRs are optimized static devices, controlled IGBT bridges, designed to maintain a
constant, pre-displayed and adjustable output current independently of load or power supply fluctuations. These
devices are specifically designed for visual aids supply, and particularly LED lights. They meet all international
standards. Control electronics of the DIAM4200 is characterized by an innovating architecture built around an
electronic board using a powerful DSP processor, associated with an internal CAN network connecting the
various parts.
An USB front socket allows the connection of a portable computer for parameter setting, this setting being
possible without live voltage. However, this link is not a hardened industrial link, such as the JBus, Ethernet or
Interbus communication ports of the CCR: all precautions must be taken not to introduce electrostatic or
electrical disturbances, which could disrupt the operation of the CCR, (using ESD protections).
The remote control interface of the CCR supports all the series networks, with or without redundancy, as
well as universal multiwire interfaces. DIAM4200 series CCRs are low costs fully static devices controlled by
high performance IGBT switches. They are designed to maintain a constant, pre-displayed and adjustable
output current independently of the load and power supply fluctuations.
These devices are specifically designed for airfield lighting on runways, taxiways, aprons. They meet both
national and international standards.
In order to do this, they use an adapted triggering and regulation mechanism that is not affected by external
interference and does not emit measurable interference in the Aviation Band between 100 and 400 MHz.
The output current remains constant with an accuracy of 100mA for mains voltage fluctuations of –5/+10%
(+/-10% for IEC type). At the rated load and the rated or higher voltage, accuracy of regulation is maintained for
all load between 0 and 100%, and for up to 30% of transformers with open secondary.
Here are some of its advantages:
Sinusoidal wave shape:
Thanks to its original power architecture, the CCR does not introduce any distortion or degradation of the
power-factor, which remains that of the load. The harmonic content rejected on the mains network is thus
particularly low, for all the range of output current and for any load. In particular, no tapping or adaptation at
load is necessary. The digital processing capability of the DSP processor allows to adapt its regulation to
any type of load (such as for example : signs). Like all the DIAM4XXX series regulators, an automatic
calibration avoids any analogical adjustments, during maintenance. In the same way, indications of alarm,
state of the CCR and all useful parameters are clearly displayed, through a simple and friendly HMI*.
Maintenance optimization:
Its internal CAN* architecture has been designed to minimize the number and the variety of the spare parts,
and to allow the best flexibility of possible modification of options. Software tools are proposed in order to
carry out fast parameter settings or diagnoses, without removing any parts.
Standards:
ICAO: Airport design manual, part 5
CENELEC: prENV 50231
FAA: AC150/5345-10 L828 & L829
AENA: PPT02-05/13 (2013)

The frame has three distinct parts: a low voltage converter stage, a low voltage compartment and a high voltage
compartment.
The Low voltage converter stage of the
CCR consist of one to three power modules,
situated in the upper section of the regulator.
The Low voltage unit contains all the
components connected to the power supply
with, for example, the main switch, the LV
protections, the electronics control
motherboard, the LV fuses and connection
terminals. It is located in the lower front part
of the CCR.
The High voltage unit, situated at the back
of the CCR, contains all the components
connected to the output loop such as the
power transformer, the lightning arrestors,
the CI-MALT (optional) and the HV part of the
insulation fault detection unit. The load
regulating plate and the load loop
connections are accessible from the front of
the device.
All these components are easily accessible from the front, the top or the back of the cabinet.

I.3.3 GENERAL ELECTRICAL FEATURES
Power supply voltage:
Single phase; 230Vac, 400Vac +10/-10%, 45 to 66 Hz
Maximum rated current: 6.6 A (other values available).
Number of Brightness Levels: maximum 8, adjustable.
Heating Brightness (“Black current”):
The CCR can produce “heating” level brightness at low current (1.8A preferred value), which is used to
remove condensation from the interior of the lamp lenses without lighting up their bulb. The symbol for
local setting is ‘B0’.
Remote Control: By voltage from 20V to 60V DC positive or negative, or dry contact, or 120Vac, serial
network, TCP/IP network (MODBUS TCP).
Remote indication:
Relays, 120VAC , 2A max, 10µA min., and/or serial network
Output power: 2.5, 5, 7.5, 10, 15, 20kVA
Power factor:
> 97% at nominal voltage and rated resistive load
Efficiency : > 80% at nominal voltage and rated resistive load.
Output Current Regulation:
Better than 100mA under the following conditions: Power supply voltage: 10% - Frequency: 45 to 66
Hz - Load: from 0 to 100%
Load adaptation:
The DIAM4200 CCR does not require load adaptation: the output voltage is purely sinusoidal at every
load and current step.
Protection:
The electronic circuitry is protected against fluctuations by the use of a Hall effect sensor for measuring
current. Electronic board manages all overcurrent, open circuit or mains under/over voltage.
LV Protection:
A set of high-power fuses (or optional circuit breaker), a set of fuses for the power supply to the
auxiliaries, and “glass” fuses on the circuit boards provide LV protection.
Lightning arrestors :
These regulators can be optionally provided with input and output lightning arrestors.
