The atg airports Micro 200 CCR, utilises IGBT H bridge technology and is specifically designed to provide a sinusoidal waveform power source to lighting circuits containing both LED and conventional lighting fixtures, plus other electronic devices.
This Constant Current Regulator is fitted with state-of-the-art electronics that monitor and adjust the output waveform many times per second to produce a sinusoidal output. Overall, these provide superior responses to load changes and circuit switching, improved protection against overcurrent or open circuit fault conditions whilst delivering superior power factors without compromising on a minimised harmonic content.
The Micro 100 Constant current regulator is a microprocessor-controlled unit integrating a high-speed control and protection loop. The control system drives a pair of power thyristors providing phase angle control to the series circuit.
These units can be operated by the airfield lighting control and monitoring system via various methods, including:
A huge range of information can be seen without the need of a laptop or other device on both CCR’s thanks to their front-mounted display.
Our Micro 100 and 200 Constant Current Regulators (CCRs) are recognised as some of the most advanced products on the market, giving you complete confidence in their reliability and reducing maintenance undertaken.
The units we supply can be operated by all airfield control and monitoring systems via a wide range of controls. Why spend time establishing how you can control your system when you can simply use what you prefer?
Tired of dragging around laptops to get the information you need? With a front mounted display, you can leave your laptop at home.
Pre-programmed with default parameters suitable for most applications, our airfield power solutions can typically be ready-to-go quickly and easily, with the minimum of fuss.
An IGBT constant current regulator, or CCR, is used to regulate the power quality in airfield lighting circuits. The CCR contains state-of-the-art electronics that monitor the waveform of the power source, adjusting it many times each second to give a reliable sinusoidal output.
Devices like ATG Airports’ Micro 200 CCR power both types of AGL lighting either tungsten halogen or primarily LED lighting fixtures.
IGBT CCRs are used for a variety of reasons in airfield lighting circuits. They can level out imperfections in the incoming mains power, providing runway and taxiway lights with a smooth sinusoidal signal that reduces the risk of damage due to excess current and other fluctuations.
An IGBT constant current regulator can balance the load across all of the LED fixtures in each runway circuit, protecting the sensitive electronics in each lighting fixture to help ensure that each LED unit function correctly.
ATG’s Micro 200 CCR contains an IGBT H-Bridge. This stands for Insulated-Gate Bipolar Transistor (IGBT) with the ‘H’ representing the shape of the circuit, with its four switching elements connected via a central cross-bar.
The IGBT H-Bridge uses Pulse Width Modulation to adjust the sinusoidal signal of the power supply thousands of times per second, improving the harmonic content of the current with a near-unity power factor. More details of this and other ATG CCRs can be found in the downloadable PDF data sheets on each page of our website.
Constant current regulators are designed to be used in extreme weather conditions, as any airfield might expect to encounter from time to time. This includes temperature ranges from -40 to +50 C, relative humidity from 10% to 95% and altitudes up to 2,000m above sea level. Again, full specifications for each product can be found in the PDF data sheet.
Each CCR is also designed to allow access to internal components without exposing other parts of the device, e.g. separate compartments for the fuses and input terminals, which do not expose the power compartment. Access panels in the front, rear and sides of the unit mean maintenance can be carried out conveniently.
Installed correctly, a CCR should provide thousands of hours of reliable operation. By definition, these units are designed to improve the reliability and consistency of the airfield power circuit. In the event of excess current, the fuses in the CCR can be replaced to restore operation, while the remainder of the AGL circuit should be left undamaged.
