TWO YEAR WARRANTY
All ElencoTMmodels are guaranteed for two full years on all parts
and service. For the first 3 months, your power supply is
covered at absolutely no charge. For the remaining 21 months,
a nominal service charge is required to cover shipping and
handling.
When returning merchandise for repair, please include
proof of purchase, a brief letter of explanation of problem,
and sufficient packing material. Before returning any
merchandise please call our service department at (847)
541-3800 to obtain a return authorization number (RMA).
Setting Current Limit (XP-605 only)
1. Adjust the current and voltage control knobs fully counter-
clockwise.
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 1/2 turn.
5. Set the maximum output current by turning the current coarse
knob clockwise.
This now limits the output current to your setting.
INTRODUCTION
Congratulations on your selection of a top quality power supply! The
XP-605 has an output of 0-30VDC @ 5A; the XP-752 has an output
of 0-50VDC @ 3A. Their features include fine and coarse controls
for voltage and current, and contains two analog volt/current meters
(XP-605); two digital volt/current meters (XP-752).
The supply incorporates an externally controlled current cutoff
circuit with an LED indicating current overload. Protected against
short circuits and overloads.
OPERATING INSTRUCTIONS
1. Check that the voltage rating of the equipment does not exceed
the power supply’s rating.
2. Plug the line cord into an AC outlet.
Constant Voltage Mode
1. Turn the current control (coarse and fine) knobs fully clockwise
and the voltage control knobs fully counter-clockwise.
2.
Press the power ON/OFF switch to ON.The CV LED should be lit.
3. Turn the voltage control knobs clockwise to the desired output
voltage.
4. Connect the positive and the negative output terminals to a load
or similar component.
Constant Current Mode
1. Turn the voltage control knobs (coarse and fine) fully clockwise
and the current control knobs (coarse and fine) ¼ clockwise.
2.
Press the power ON/OFF switch to ON.The CV LED should be lit.
3. Connect the positive and the negative output terminals to a load
or similar component.
4. Turn the current control knobs clockwise to the desired output
current value.
Note XP-752:
Current limiting less than ½A 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.
