Constant current power supply CCR 961

AC/DC

Easy to adjust, operate and maintain High efficiency – low losses – high Mean Time Between Failure (MTBF) Full digital regulation circuit, with high output accuracy Built-in EMC filters Solid-state operation with no relays eliminates mechanical failures TKH Airport Solutions CCR 961 supplies precision output levels to power series lighting circuits on airport runways and taxiways containing both LED and conventional Halogen lighting fixtures. The CCRs are developed in a modular way and can be customized depending on project requirements. Key features General: • Modular concept, enabling the CCR to be customized depending on project requirements • Fixed size control unit (independent of the CCR specifications) which can easily be replaced • High efficiency – low losses – high Mean Time Between Failure (MTBF) • Full digital regulation circuit, with high output accuracy • Built-in EMC filters • Solid-state operation with no relays eliminating mechanical failures • All CCR configurations stored on memory board, allowing transfer to other regulator modules for easy and fast maintenance • Hour meters for 100 % intensity and total time • Lamp fault detection with two alarm levels • Earth fault detection with two alarm levels • 7 individually adjustable intensity steps • Soft start facility during normal switch-on, but output current re-established within 0.5 s for short breaks in power supply Environmental conditions: • Designed for continuous indoor operation in an ambient temperature of 0 °C to +50 °C and maximum relative humidity of 95 %
