    3. OPERATION WARNING: Before connecting line power to your power supply, make sure that the AC input voltage is correct for your power source. TURN-ON CHECKOUT PROCEDURE. a) Turn A-adj control fully counter clockwise. b) Set AC power switch push to on position, digital display and CV lamp should light. c) Turn VOLTAGE controls fully counter clockwise to ensure that output decreases to OV dc then fully clockwise to ensure that output voltage increase to the maximum output voltage.

  • Page 8: Constant Current Operation

    CONSTANT CURRENT OPERATION To set up a power supply for a constant current operation, proceed as follows: a) Turn A-adj control fully counter clockwise to ensure that output decreases to 0 A, and then on power supply. b) Adjust V-adj control (no load connected) for maximum output voltage allowable(voltage limit), as determined by load conditions.

    4. MAINTENANCE WARNING: The following instructions are for use by qualified personnel only. To avoid electrical shock, do not perform any servicing other then contained in the operating instructions unless you are qualified to do so. Fuse Replacement If the AC fuse blows, the CV or CC lamp will not light and the power supply will not operate. If the DC fuse blows, the CV or CC lamp and digital display is light but DC OUTPUT will not operate.

    5. CALIBRATION ADJUSTMENT ADJUSTMENT OF THE RATING VOLTAGE. Connect digital multimeter across output terminals of supply and set the DC volt position. b) Turn on supply and push on DC OUT push button switch. Adjust voltage controls (COARSE, FINE) fully clockwise. d) Adjust S203 for a reading of rate volts x 1.05 on the digital multimeter.
