Abstract

The present invention relates to a power supply arrangement (60) for providing electrical power to monitoring apparatus. The power supply arrangement is for use with a traffic control system. The power supply arrangement (60) comprises a rectifier arrangement (68) which is configured to be connected to a source of alternating current (AC) power (62, 64) comprised in the traffic control system, to draw an AC signal from the source and to provide a first direct current (DC) signal in dependence thereon. The power supply arrangement further comprises a regulation circuit (72) configured to receive the first DC signal and to provide in dependence thereon a second DC signal for providing power to circuitry comprised in the monitoring apparatus, the regulation circuit (72) being configured to maintain provision of the second DC signal while accommodating a variation in the first DC signal of at least fifty percent.
