INTRODUCTION Congratulations on your selection of a top quality power supply! The XP-605 has an output of 0-30VDC @ 5A; the XP752A has an output of 0-50VDC @ 3A. Their features include fine and coarse controls for voltage and current, and contains two analog volt/amp meters (XP-605); two digital volt/amp meters (XP-752A). The supply incorporates an externally controlled current cutoff circuit with an LED indicating current overload. Protected against short circuits and overloads.
OPERATING INSTRUCTIONS 1. Set the AC input voltage switch on the back to the correct setting and the correct fuse (6A - 115V, 3A - 230V) installed. 2. Set the power switch to the off position. 3. Plug the power cord into the power socket on the back of the unit. 4. Plug the power cord into an AC output. Note: Make sure enough space is left for heat dissipation. 5. Check that the voltage rating of the equipment does not exceed the power supply’s rating. Constant Voltage Mode 1.
Note XP-752A: Current limiting less than 1/2A or a shorted output activates the short circuit protection, turning the unit off. To reset unit, remove the short or load and readjust current limiting control. Setting Current Limit Protection Mode 1. Adjust the current and voltage control knobs to the desired output voltage. 2. Short the positive to the negative output terminal. 3. Press the power ON/OFF switch to ON. The CC LED should be lit. 4. Turn the voltage coarse knob clockwise 1/4 turn. 5.
• Never move or pull the power supply using the power cord or output lead. • The unit is designed for INDOOR USE ONLY.
