Page 12: Environment
3.3 Environment The normal ambient temperature range of this instrument is from 0° to 40°C (32° to 104°F). Operation of the instrument above this temperature range may cause damage to the circuits. Do not use the instrument in a place where strong magnetic or electric field exists as it may disturb the measurement. 3.4 Equipment Installation, and Operation Ensure there is proper ventilation for the vents in the SPS power supplies case. -

4.THEORY OF OPERATION Block Configuration of SPS- System The SPS-Series comprise a Bridge rectifier, a Pulse Width Modulation, a Driver Circuit, a Driver Transformer, a Rectifier Circuit, a Voltage Control Circuit, a Current Shunt, an Output Filter, a Voltage/Current Adjusting Circuit, a Buffer Circuit, an Error Amplifier, an Opto-Isolator, and an Auxiliary Switching Supply and etc. - Page 14 Description of Circuit Theory 1) +10V Voltage reference circuit? Start up the circuits of R306 and D302 to ensure the output voltage of OPA U301, PIN 1 is in positive status when power is on. At this moment, the output voltage of PIN 1 will pass through R307 to maintain the voltage of both ends of ZENER DIODE ZD301(6.2V) to 6.2V.

6.OPERATION INSTRUCTIONS 6-1.Precaution (1)AC input AC input should be within the range of line voltage± 15% 50/60Hz. WARNING: To avoid electrical shock, the power cord protective grounding conductor must be connected to ground. (2)Installation Avoid using the power supply in a place where ambient temperature exceeds 40℃. The heat sink located at rear of the power supply must have sufficient space for radiation. - Page 23 (3) Output Current/Temperature Cure Line Chart: 100% Output Current Environment Temperature (℃ ) Artisan Technology Group - Quality Instrumentation ...

Page 25: Setting Current Limit
6-2.Setting Current Limit (1) Determine the maximum safe current for the device to be powered. (2) Temporarily short the (+) and (-) terminals of the power supply together with a test lead. (3) Rotate the COARSE VOLTAGE control away from zero sufficiently to have the CC indicator lightened. (4) Adjust the CURRENT control for the desired current limit. - Page 26 Similarly, crossover from the constant current to the constant voltage mode automatically occurs from a decrease in load, a good example of this would be seen when charging a 12 volt battery. Initially, the open circuit voltage of the power supply may be preset for 13.8 volts.

7. MAINTENANCE WARNING The following instructions are used by qualified personnel only. To avoid electrical shock, do not perform any servicing other than the operating instructions of the manual unless you are qualified to do so. 7-1.Fuse Replacement If the fuse blown, the CV or CC indicators will not light and the power supply will not operate. The fuse should not normally blow unless a problem has developed in the unit. -
Page 28: Adjustment
7-3.Internal adjustments The unit was accurately adjusted at the factory before shipment. So, readjustment is suggested only when the accuracy of circuit is affected by the repair, or when you have the reason to believe that the unit is out of accuracy. The recommended calibration device is a multimeter with an accuracy of ±... - Page 29 Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com...

Page 30: Cleaning
7-4 Cleaning To clean the power supply, use a soft cloth dampened in a solution of mild detergent and water. Do not spray cleaner directly onto the instrument, since it may leak into the cabinet and cause damage. Do not use chemicals containing benzine, benzene, toluene, xylene, acetone, or similar solvents.
