DIAM4000 Single-phase Constant Current Regulator COMPLIANCE STANDARDS ICAO Aerodrome design manual, part 5 IEC (61822) CENELEC (ENV 50231) STNA (91068 rev.93) FAA (AC150/5345-10F – L828/L829) AENA (PPT002 ed4-2004) APPLICATIONS 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. ADVANTAGES 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. Purchase and life-cycle costs : DIAM4000 series constant current regulators represents the best compromise on the market between high performances, maintenance services and the most reduced cost, thanks to an optimised design and a latest state-of-the-art digital electronic technology.

DIAM4000 : Technical characteristics GENERAL PRESENTATION Each DIAM4000 is delivered into a metal frame with lifting rings. It includes 3 distinct parts: an "electronic" compartment, a “Low voltage” compartment and a "high voltage" compartment The Electronic part includes an electronic board whose design uses last digital technologies; it is fixed at the front panel of the device. This front sheet supports the user interface delivering any useful information, and allowing all local or distant operations. Internal parts are accessible from the front or the top. The Low voltage compartment...

DIAM4000 : Display and Menus DISPLAY FUNCTIONALITY CONFIGURATION MENU The display shows 2 lines of text allowing to monitor many parameters, values and warnings. The lower line sets the definition of the keypad. The preferred information displayed can be changed in “STOP” mode, and can be chosen (long press on STOP) among : The “Configuration” menu allows to set all basic parameters of the CCR to the processor (in case of mother board replacement, for example) : “Output current Io” – “brightness state Bx” “Output current Io” – “Output power Po” “Output current Io” – “Output voltage Uo”...

Constant Current Regulator – DIAM4000 ORDERING INFORMATION The DIAM regulator is identified by a serialised ordering number which indicates its type and particularity.
