During actual operation if a load change causes the voltage limit to be exceeded the power supply will automatically cross over to constant voltage operation at the preset voltage limit and output current will drop proportionately c Adjust CURRENT control for desired output current while depressing CC SET button CC LED will not light until the supply is loaded Connecting Loads The output of the supply is isolated from earth ground Either output terminal may be grounded or the output can be floated up to 240 volts off ground Each load should be connected to the power supply output terminals using separate pairs of connecting wires This will minimize mutual coupling effects between loads and will retain full advantage of the low output impedance of the power supply Each pair of connecting wires should be as short as possible and twisted or shielded to reduce noise pickup If a shield is used connect one end to the power sup ply ground terminal and leave the other end unconnected Operation Beyond Rated Output The output controls can adjust the voltage or current to values above up to 5 the rated output as indicated on the front panel display Although the supply can be operated in the 5 overrange region without being damaged it can not be guar anteed to meet all of its performance specifications in this region Pulse Loading Considerations The power supply will automatically cross over from constant voltage to con

TANT CURRENT ERROR CONSTANT VOLTAGE ERROR AMP Figure A 1 Block Diagram PRINCIPLES OF OPERATION Throughout this discussion refer to both the block diagram of Figure A 1 and the schematic diagram at the rear of the manual The input AC line voltage is stepped down by the power transformer and applied to the recti fier and filter The rectifier filter converts the AC input to raw DC which is fed to the positive output terminal via parallel series regulator Q1 and Q3 and current sampling resistor R2 The regulator part of the feedback loop is made to alter its conduction to maintain a constant output voltage or cur rent The voltage developed across the current sampling resistor is the input to the constant current error amplifier The constant voltage error amplifier obtains its input by sampling the output voltage of the supply Any changes in output voltage or current are detected amplified by the error amplifier and driver and applied to the series regulator in the correct phase and amplitude to counteract the change in output voltage or current Two error amplifiers are included in a CV CC supply one for control ling output voltage the other for controlling output current Since the constant voltage amplifier tends to achieve zero output impedance and alters the output current whenever the load resistance changes while the constant current amplifier causes the output impedance to be infinite and changes the outpu
