-The light barrier measures the speed of the fly masses. She is a necessity for the power measurement. If speed is not measured correctly, the power measurement is not correct either. The displayed speed values in the SRMWin-Software - e.g. during a performance test – do not correspond to real speed values.

-The power supply has been especially designed to suit the SRM Performance Ergometer. The power supply changes the magnetic field in the eddy current brake very rapidly to ensure a constant rotational speed in isokinetic mode. In the isokinetic mode it is necessary to reduce the braking power to near zero when the cranks are in vertical position. In horizontal position the braking power has to be up to 4000 watts. This is necessary to maintain the predetermined rotational pedaling speed. This means that at a cadence of 120 rotations per minute the magnetic field in the brake has to be established and abolished four times per second.
+The power supply has been especially designed to suit the SRM Performance Ergometer. It supplies power to the ergometer, including the PowerControl Ergometer. The operating mode of the power supply is indicated by a green LED display.
-The power supply operates with 220 Volts, and incorporates fuses of 1.3 A. The power point which is used for the power supply has to be well earthed (grounded) in order to avoid that the athletes become electrostatically charged. WARNING: Operation of the ergometer through an unsatisfactorily earthed power point can damage the health of the athlete and the physiologist and can also lead to wrong ECG readings.
+Place the power supply in dry, well aired condition. Avoid switching the power supply on and off in quick succession. The power supply does not need any maintenance.

-The operating mode of the power supply is indicated by a green LED display. The yellow LED display indicates the operation of the brake. The yellow LED has to flash during isokinetic mode.
-−
-Place the power supply in dry, well aired condition. Avoid switching the power supply on and off in quick succession. Never clean the power supply with water or other fluids, the electronics will be damaged.
-−
-The current transmitted by the power supply is +/- 24 Volt. The power supply charges the PowerControl unit. If the PowerControl is not charged over a period of about 3 months, it may lose the programmed operating parameters. In this case the user has to charge up the PC via the dedicated charger and enter all operating parameters again with the software SRMWIN.
-−
-The power supply does usually not need any maintenance. Wipe with a dry cloth and be sure that no moisture gets into it.
