ELECTRICAL
FEATURES
•
Power supply voltage:
Single phase; two series :
FAA type : 208Vac, 220Vac, 240Vac, 277Vac, 400Vac, 480Vac –5/+10%, 50 or 60 Hz
±
5%.
IEC type : 220Vac, 230Vac, 240Vac, 380Vac, 400Vac, 10/-10%, 50 or 60Hz
±
5%
•
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 (1.5A prefered), 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,
and/or serial network.
•
Remote indication:
FAA type : Relays, 120VAC , 2A max, 10µA min., and/or serial network
IEC type : Static dry contacts relays, 48Vdc, 0.1A max, and/or serial network
•
Output power: 1, 2.5, 4, 5, 7.5, 10, 15, 20, 25, 30 kVA
•
Power factor:
FAA type : > 90% (2.5 to 10kW CCRs) or > 95% (15 to 30kW CCRs), at voltage and rated resistive load
IEC type : > 90% at nominal voltage and rated resistive load
•
Efficiency : > 90% at nominal voltage and rated resistive load.
•
Output Current Regulation:
Better than
±
1% under the following conditions: Power supply voltage:
±
10% (IEC) or –5/+10% (FAA) -
Frequency:
±
5% - Load: from 0 to 100%
•
Load adaptation:
The output transformer is equipped with an epoxy plate including adjustment taps in order to adapt the
rated output voltage of the CCR to the present load. Two brass straps allow load adaptation with steps
of 12.5%, between 12.5% and 100% (8 possibilities).
•
Protection:
The electronic circuitry is protected against fluctuations by the use of a Hall effect sensor for measuring
current, and fibre optics for thyristors control. 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.
