I1742 NI1744 NI1762 NI1764 The NI Smart Camera offers an innovative lighting controller that directly powers third party current controlled lights With other smart cameras a lighting controller that drives a light must be purchased separately The Direct Drive lighting controller is capable of powering a variety of third party lights For a current controlled light higher current produces more light up to the maximum current rating of the light The maximum current rating of the light is specified by the manufacturer and based on the average amount of power that can be safely dissipated by the light The Direct Drive controller can operate in continuous or strobed mode When operating in strobed mode the controller can provide more current to the light than in continuous mode The average power dissipated while strobing the light for a short period of time at a higher current can be comparable to the average power dissipated while running the light continuously at a lower current Table 4 1 shows the maximum allowed current for continuous mode and strobed mode Table 4 1 Maximum Allowed Current for Direct Drive Lighting Controller Maximum Strobed Current Maximum Continuous Current 1A 500 mA For applications with a pause between exposures while new parts move into position you can strobe the light which allows the use of higher current and produces more light thus you can reduce the exposure time A shorte
