DIAM4000 series CCRs are low-cost fully static devices controlled by two
thyristors. They are designed to maintain a constant, pre-displayed and
adjustable output current independently of load or power supply
fluctuations. These devices are specifically designed for airfield lighting on
runways, taxiways or aprons. They meet all international standards.
Electronics, using the latest digital technology, can be controlled and
monitored by the mean of the most popular serial networks with or without
redundancy, as well as the most simple universal multiwire interface.
Flexibility of operation :
The large semigraphic alphanumeric display combined with a menu type
keyboard allows the CCR to be configured without connecting a computer.
Regulation is fully digital, which enables parameters to be simply adapted
in case of particular load or special application. Auto-calibration eliminates
the use of tedious setting, in case of long-time scheduled maintenance.
Emergency and warning messages are clearly displayed, as the current
state of the CCR or all input or output electrical measurements.
Maintenance optimisation :
These regulators show a very simplified architecture both for electronics,
LV part and HV power unit : It has been optimised to keep the number and
variety of spare parts to a minimum, in order to facilitate maintenance.
Software tools allow a fast fault diagnosis and test, without dismantling.
