Page 2: Safety Summary
This operating and service manual covers three dual range constant voltage source. The CC SET push button allows the Agilent power supplies, E3610A, E3611A, and E3612A. All current limit value to be conveniently set using the CURRENT models are compact, general purpose bench supplies that control without shorting the output. - Page 3 Three output terminals are provided on the front panel. They OUTPUT : E3610A: 0 to 8 V, 0 to 3 A or 0 to 15 V, are isolated from the chassis and either the positive or nega- tive terminal may be connected to the ground terminal.

Turn CURRENT control fully counter clockwise to ensure front panel controls and indicators illustrated in Figure 2 and that output decreases to 0 A, and than turn on power sup- ensures that the supply is operational:...
- Page 6 Pulse Loading Considerations but will decrease the safety provided by the current limiting The power supply will automatically cross over from constant- circuit. A high-current pulse may damage load components voltage to constant-current operation in response to an before the average output current is Iarge enough to cause increase (over the preset limit) in the output current.

Page 7: Principles Of Operation
APPENDIX SERVICE INFORMATION Figure A-1. Block Diagram PRINCIPLES OF OPERATION current source - it can not be both; transfer between these two modes is accomplished at a value of load resistance equal to the ratio of the output voltage control setting to the output current control setting. Throughout this discussion, refer to both the block diagram of Figure A-1 and the schematic diagram at the rear of the manual. - Page 8 A = Calibration adjustments. Constant Voltage(CV) Test c. Turn up output voltage to the full rated value (E3610A: 8.0 V, E3611A: 20 V, E3612A: 60 V) as read on the digital voltmeter. The measuring device must be connected as close to the output termi- d.
- Page 9 to the full rated value of power supply. d. Set the electronic load to transient operation mode between b. Connect the unit to the ac power line through a variable one half of unit's full rated value and unit's full rated value at a 1 autotransformer which is set for low line voltage(104 Vac for KHz rate with 50% duty cycle.
- Page 10 the load current is fed to the extremes of the wire leading to the resis- tor while the sampling terminals are located as close as possible to the resistance portion itself. Generally, any current sampling resistor should be of the low noise, low temperature coefficient type end should be used at no more than 5% of its rated power so that its tem- perature rise will be minimized.
