Our Products

CCR – Constant current regulators light up the airfield runways to desired visibility levels to ensure safe & proper aircraft landing. This calls for lighting that is reliable and problem free.

We provide different ratings of CCR. Our standard range is 4KW, 7.5KW, 8KVA, 10 KW, 15KW, 16KVA, 20KW, 30KW, 50KW & 70KW.

Salient Features of CCR

• Static Thyristor controlled natural air cool type in ratings from 4kW to 70KW
• High efficiency >92% and high power factor >.95, optimizing the wave form and the power factor
• Built in soft start while starting, change of brightness steps and automatic resumption after power restores.
• Dual Over current protection for redundancy towards protection of runway circuit lamps
• Protection to CCR in case of remote control cable fault
• Ambient operating temperature from -40 degree Centigrade to +55  degree Centigrade
• Simple design, sturdy construction and epoxy powder coating paint.
• Remote reset capability
• Output current maintained within the range even with 30% lamps fused.
• Open circuit protection
• Dual Over current protection
• Plug -in printed circuit boards
• Thyristor type
• Air-cooled
• Ammeter (0.5% accuracy)
• Regulation + 1% over 0 to 100% load and + 10% line voltage variations.

To maintain the quality we extensively conduct tests on CCR’s. Some of these tests conducted are as below:

• Regulation Test
• Remote Control Test
• Temperature Rise Test
• Efficiency
• Power Factor
• Crest Factor
• Low Temperature ( Type test certification acquired )
• High Temperature with Humidity Test ( Type test certification acquired )
• Electromagnetic Interference Tests
• Basic Impulse Insulation Level (BIL) Tests
• Dielectric Tests.
• Protective Device Tests
• Output Current Surge
• Monitor Test

We confirm that all industry standards are met and ensure the reliability and durability of all the products.

Annual Maintenance of CCR
We also work with airfields and help in complete maintenance of CCR through Annual maintenance contracts. By letting the experts at Nasu maintain your CCR at top performance levels you can ensure the safety and long term cost effectiveness of the CCR.
