INTRODUCTION
Congratulations on your selection of a top quality power supply! The XP-
770 is a triple-output regulated power supply providing two variable outputs
(0-20V@ 2A) and one fixed (5V @ 3A). Four LCD displays allowing the
output voltages and currents to be displayed simultaneously. The variable
outputs can work independently, in series, or in parallel modes. The highest
output voltage is the sum of twice the voltage value in series mode and
the highest output current is the sum of twice the current value when in
parallel mode.
FEATURES
Four LCD displays for voltage and current
Independent voltage and current controls
Constant voltage (CV) or constant current (CC) operation
LED indication for CV and CC for variable outputs
Series and parallel mode for variable outputs
Overload and short protected.
Selectable AC input voltage, 115 or 230VAC
SAFETY PRECAUTIONS
Certain safety precautions must be observed when this power supply is
used with external circuits that are connected to AC power lines. There is
always some danger when working with electrical equipment or circuits
that operate at hazardous voltages. You should thoroughly familiarize
yourself with the equipment before using it. High voltage may appear at
unexpected points in defective equipment.
The XP-770 is equipped with a three-wire line cord which grounds the
chassis to power line ground. Do not cut off or disable the ground plug.
The power supply secondary circuits are isolated from the 115/230V
primary circuit via the power transformer. When working with other
equipment, this may not always be the case. Always be familiar with the
equipment rating. Keep in mind that defective equipment can have
dangerous voltages in unexpected places.
OPERATING INSTRUCTIONS
1. Set the AC input voltage switch on the back to the correct setting and
the correct fuse (4A - 115V, 2A - 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.
