Circuit arrangement for monitoring a power to be delivered at a medical, particularly a dental device

摘要

To be able to monitor a downward or upward transgression of a power to be delivered at a device in the event of a malfunction of the control electronics, it is proposed to generate the operating voltage (UB) for the device (1) by means of a voltage source (4) which is preferably controlled by feedback (5) and to compare the output voltage (US) with a reference voltage (UR1) and to monitor the resultant control voltage (x1 = US - UR1), a single generator (9) being activated in the case of a deviation from particular limit values to be individually established. <IMAGE>
