Power Stage The power stage is composed of a 230VAC transformer protected at the input by 2 antisurge fuses of 2A followed at the output by a bridge rectifier and filter capacitor The output voltage VDC1 is is approximately 24VDC and unregulated and depending on the power required The transformer is also protected by an internal thermal cutout that cannot be reset The available power enables several functions to be controlled simultaneously The VDC1 also passes through two regulators that supply voltages VDC2 15VDC 3V for the analogue components comparators battery charging control circuit etc and VDC3 3 3VDC 10 for the logic components control pendant etc The power stage is also protected against electrostatic discharges ESD of 20kV Function Control The actuators are controlled by relays In order to protect these relays from electrical sparks during switching the second FET transistor checks the delay power when a function is activated thus allowing the switches to close with no voltage In the same way when a function control is released the FET transistor cuts the power before the contact opens Overload limiting This is provided by permanently controlling the current at the output of each motor In the event of overload or mechanical blockage the supply of the relevant motor is cut off by a control transistor without affecting the operation of the other motors except for specific situations In thi
