INSTALLATION
1. This power supply is designed for indoor use only , put the unit in a well ventilated place and allow at least 50mm(2 in.)
space on two sides and the back to allow sufficient fan cooling.
2. Check for the correct input AC voltage with the rating label on the power supply
Make sure your mains plug is of 3 pin version and the ground pin is effective as the grounding of the power supply will
prevent electrical shock caused by leakage.
3. Turn on the power supply for a few minutes , the power switch(1) should be lit and the indicator (2) should be in green.
4. Turn off the power supply and connect the equipment with correct polarity.
5. Turn on the power supply first , then turn on the equipment .
6. When the operation is finished, turn off the equipment first , then turn off the power supply.
FINE TUNING THE OUTPUT VOLTAGE
(13.3 ~14.5V
for SPA-8230 & 26.6 ~ 29V for SPA-8232
)
This regulated power supply has been factory preset at a stable DC output.
Rarely you need to do any fine tuning under normal operation .
However , should the need for specific precise output voltage other than the preset voltage is required , refer to the following
procedure.
1. Let the power supply warm up for about 15 min.
2. Turn the power supply over with the bottom up and connect a digital multi-meter(DMM) with at least 2 decimal read out to
the main output terminal (4).
3. Locate the fine tune access hole (8) on the bottom as shown in Fig.1.
4. Insert a slim flat head screw driver to get to the trimmer as shown in Fig.1.
5. Carefully and slowly turn the screw driver clockwise or anti-clockwise while keeping an eye on the DMM for your desired
voltage setting.
6. Measure again the output voltage to re-confirm your new setting after returning the power supply to its normal operation
position.
