PCR273 High Power factor State of the art Current Regulator. For 2,8—6,6Amp Series circuits in Airfield lighting systems tP Paten ending The PCR 273 Current Regulator is designed for use in airfield lightning systems that use constant current (2,8-6,6Amps) for power distribution to Information and Direction signs. The unit contains one complete lamp ballast for 36 up to 58W fluorescent TL tubes. The PCR 273 presents a very high power factor seen by the Constant Current Regulator (CCR). This contributes to a good power-factor for the entire system and lower operating costs as result.
