Camera Interface2-34 Basler A500kPRELIMINARY2.8 DC PowerThe A500k requires 12 VDC (± 10%) power. The maximum power consumption is 6 W for theA504k/kc, 5.4 W for the A503k/kc, and 3 W for the A501k/kc. The current during constant operationis 500 mA max. for the A504k/kc, 450 mA max. for the A503k/kc, and 250 mA max. for theA501k/kc. Peak currents may occur. We recommend using 1.5 A power supplies.The camera is equipped with an undervoltage lockout. The camera has no overvoltage protection.Ripple must be less than 1%.2.9 Power Control: Full Function and StandbyThe camera can be set into a standby mode with register settings (see section 4.2.11). In standbymode, the camera’s power consumption is reduced to 2.5 W for the A504k/kc and A503k, and1.8 W for the A501k/kc. The Camera Link output is no longer fed, the sensor does not react anymore. The monitor output available for the A504k/kc is no longer fed. The camera remembers thework set configuration. The serial communication is still operable. When the camera is set backto full function, it takes maximum 0.5 s until it is fully operable. During this startup time, the ExSyncsignal is not recognized reliably which can have the effect that the first image is not exposedcorrectly.Power up time after power was off entirely takes a maximum of 3 s.2.10 Status LEDWhen the LED on the back of the camera is not lit, it means that no power is present. When theLED is lit, it means that power to the camera is present.Keep in mind that the circuit used to light the LED on the camera does not perform a voltage rangecheck. If power to the camera is present but it is out of range, the LED on the camera may be litbut the camera will not operate properly.When the LED on the back of the camera is orange this indicates signal integrity. At power up, theLED will light for several seconds in orange and sometimes green as the microprocessor in thecamera boots up. If all is OK, the LED will then remain orange continuously.If an error condition is detected at any time after the microprocessor boots up, the LED will beginflashing an error code. See section 6 for details.L A Hirose plug will be shipped with each camera. This plug should be used to termi-nate the cable on the camera's power supply.For proper EMI protection, the power supply cable attached to this plug must be atwin-core shielded cable. Also, the housing of the Hirose plug must be connected tothe cable shield and the cable shield must be connected to earth ground at thepower supply.Make sure that the polarity is correct.
