MULTI-OUTPUT POWER SUPPLY USER MANUAL 5. OPERATION INSTRUCTION 5-1. Precaution (1) AC input AC input should be within the range of line voltage ± 10% (230V +10%~-6%) 50/60Hz. WARNING. To avoid electrical shock, the power cord protective grounding conductor must be connected to ground. AVERTISS: Pour éviter les chocs électriques, le fil de terre du cordon secteur doit impérativement être relié à la terre. (2) Installation Avoid using the supply in a place where ambient temperature exceeds 40℃.

MULTI-OUTPUT POWER SUPPLY MULTI-OUTPUT POWER SUPPLY USER MANUAL 5-4. Operation Mode (1) Independent Operation The “CH1” and “CH2” supplies each provide a 0 to rating volts output at up to rating amps. This procedure covers the use of the CH1 and CH2 supplies only when they are used independently from each other.

MULTI-OUTPUT POWER SUPPLY USER MANUAL adjust the maximum current value. Because current through the two supplies must be equal when they are being used in series, the lowest CURRENT control setting will set the maximum output current. C. Adjust the output voltage to the desired level by using the CH1 VOLTAGE controls. D. Turn off the power supply and the equipment to be powered during hook-up. E.

MULTI-OUTPUT POWER SUPPLY USER MANUAL MULTI-OUTPUT POWER SUPPLY USER MANUAL (4) CH3 Power Supply Operation The CH3 supply provides 2.2~5.2V(GPS-4302/4303) and 3~6V(GPS-4251) DC output with 3 amps (GPS-3303&4302), 1 amp (GPS-4303) and 2.5 amp (GPS-4251) current capacity. The supply is ideal for us with TTL circuits (GPS-3303 5V Fixed). A. Turn off the power supply and the equipment to be powered during hook-up. B.

To avoid electrical shock, do no perform any servicing other than the operation instruction of the manual unless you are qualified to do so. 6-1. Fuse Replacement If the fuse blows, the CV or CC indicators will not light and the power supply will not operate. The fuse should not normally open unless a problem has developed in the unit.

MULTI-OUTPUT POWER SUPPLY USER MANUAL K. Set output off by adjusting the trimmer potentiometer (VR903 CH2, VR703 CH1) so that the CH1(CH2) meter also reads rating amps (invalid for GPS-2303). (2) Series Tracking Adjustment A. Set the supply to Tracking series mode by engaging the left Tracking switch and releasing the right tracking switch. B. Set the CH2 CURRENT control to midrange and set the CH1 supply voltage controls to minimum (fully counterclockwise). C.

MULTI-OUTPUT POWER SUPPLY USER MANUAL D. Set output on by adjusting VR702 so that the CH3 meter also reads rating amps (invalid for GPS-3303). E. Connect a variable load (load must be rated to handle a power of at least 30W) across the output terminals and connect the multimeter to read the output current, then adjust the load on the multimeter to show an output current at 3.25A for GPS-3303&4302, 1.20A for GPS-4303 and 2.75A for GPS-4251.
