Procon SPS-8041 User Manual

SPS-8041 SWITCH MODE POWER SUPPLY

USER’S MANUAL

INTRODUCTION

The SPS-8041 Switch Mode DC Power Supply provides high power output for its small size and weight. It is
suitable for a variety of applications as it provides 3V, 4.5V, 6V, 7.5V, 9V and 12V selectable DC output. The
SPS-8041V provides a continuously variable output (pot adjustable) between 6 and 12 Volts.

Please read these instructions carefully and follow them to prevent abuse or misuse of the power supply. These
instructions must be kept for future reference.

FEATURES

1. Lightweight and small in size: This switch mode power supply has the advantage of small size and

weight in comparison to linear mode power supplies.

2. High Efficiency: This unit operates with efficiency greater than 80% under normal conditions.

3. Overload Protection: Current control circuitry (hic-cup mode) is used to prevent overloading of the

power supply. The power indicator will dim when overload conditions occur.

4. Output voltage is adjustable 3V, 4.5V, 6V, 7.5V, 9V, 12V DC.

INSTALLATION

1. DO NOT place the unit in dusty or highly humid locations. DO NOT place the unit in direct sun-light

or locations subjected to high temperatures.

2. Place the unit in a location which provides unobstructed air circulation.

3. DO NOT place the unit close to TV sets or CRT monitors.

4. The unit is for Indoor Use only.

CAUTION

1. DO NOT use the unit for powering devices that require higher current than the maximum - otherwise

damage may occur to the unit.

2. DO NOT use the unit for lamps or motorized equipment which requires higher current than the

maximum at startup. Damage to the unit may occur.

3. DO NOT replace the fuse and operate the unit before rectifying the problem that caused it to fail.

Always replace the fuse with the same rated type.

4. If the external cable or cord of this unit is damaged, it must be replaced by the same or equivalent unit

from the manufacturer or service agent.

SAFETY PRECAUTIONS

1. NEVER remove the cover of the power supply with the AC power connected. Allow the unit to cool

before opening the cover. Some components may burn your hand in the event of a component failure.
Only qualified personal should open the cover.

2. NEVER touch the unit with wet hands or allow it to become wet.

3. NEVER operate the unit if foreign materials such as metallic objects, liquids or other debris have fallen

inside. Return to the manufacturer or dealer for checking and repair.

4. NEVER operate the unit if it has been damaged. The voltage regulation circuitry may have been disabled,

resulting in high voltage and damage to your equipment.

5. NEVER allow foreign objects to come into connect with the DC output terminals.

6. NEVER block the cooling vents on the sides and top of the power supply.

7. NEVER adjust the output voltage whilst connected to your equipment. Switch off first!

8. ONLY connect to the AC mains outlet when in use, at all other times disconnect the power supply from

the AC mains outlet.

CONNECTION AND OPERATION

1. Make sure the input AC power source is as per the label before plugging in the unit.

2. Adjust the output voltage to match that of your equipment by pressing the lock button and moving the

lever left or right. Warning, high voltages may appear on the output when switching voltages. Always
turn off the power supply whilst selecting the voltage. With voltage sensitive equipment, always check
the output using a DMM or Voltmeter.

3. Connect your equipment to the unit. Positive polarity to red (+) and negative polarity to black (-).

4. When ready, turn ON the power supply and then turn ON your equipment.

5. When finished, turn OFF your equipment and then turn OFF the power supply.

Note: When using a DC output plug, check that the input to your device is centre positive or centre negative. If
centre positive align ‘TIP’ with ‘+’ on the plug, if negative align the ‘-’ with ‘TIP’. Always connect the red lead
to the ‘+’ terminal and the black lead to the ‘-’ terminal on the power supply.
