Page 12 This circuit permits sensing the voltage at the load terminals instead of at the power supply terminals. Thus regulation loss caused by drops in the load leads is compensated for. The influence from the resistance in the ''sens e" leads is negligible as a low (a f ew mA) and almost constant current flows through these.

Page 14 0 _I O ---- I N T Load Figure The power supply output voltage can be modulated by an external low power signal. This mode of operation is initially intended to give a possibility to add a variable amount of ripple to the output voltage. This is useful for example, when a circuit has been developed using a practically ripple free regulated power supply as power source,...

Page 27 The CV- CC indicator" monitors in the "OR-gate " if the " CV error ampli fier' ' is controlling output voltage or current. If the " CV error amplifier" controls the output it implies that RAC PAC is under constant voltage operating condition and the " CV- C C indicator' ' lights the CV lamp.
Page 28 Figure 2 1 illustrates the waveform of the rectified voltage with low respec tively high voltage and current. The ' ' Rectifying circuit" and filter operate as a coars e regulator . Its task is to supply a rectified voltage to the s eries regulator which is a few volts higher than the output voltage.
Page 29 The ripple after the filter is in the order of a few volts . E . F I R I N G C I R C U I T The " Firing circuit" is to supply pulses to the thyristors at the correct moment each half period.
Page 30 By applying a constant voltage across R40+ P53 , the Miller capacitor C 5 1 will be discharged b y a constant current a s the base current o f T55 is small . A linear sweep will thus appear at the collector of T55 . R43 and R44 (circuit diagram) are protection resistors which have no in fl uence on the b asic .
