SunPower SPS-035 User Manual

SPS-035 / SPS-050 / SPS-060
SDS-030
Please read this user's guide carefully before setup.
Input:
1. Input range:
SPS-035 / SPS-050 / SPS-060:
Universal full range AC 85V ~ 264V or DC 120V ~ 375V
SDS-030A: 9.5 ~ 18VDC / SDS-030B: 18 ~ 36VDC / SDS-030C: 36 ~ 72VDC
2. Inrush current: When turn on input power source, there is peak current (inrush
current) running through filter capacitor of power supply. During power supply
operating, it is important not to turn off input power source and then immediately
turn on it again, otherwise, it may shorten power supply's life.
Inrush current could be several to tens times of the normal current. It is important
to make sure input wiring, fuse and SW are able to carry inrush current.
3. For input specification, please refer to the label on the product or visit
www.sunpower.com.tw for newly update data.
Output:
1. The output voltage adjustable range is ±10% of rated output voltage. As output
power is V x A , when adjusting V
0 0
ex.:
For SPS-035-05, the rated output voltage is 5V, max output current is 7A: If
adjusting output voltage to 5.5V, should decrease max output current to 6.3A as
well; and even if adjusting output voltage to 4.5V, max output should not be over
7A.
2. For output specification, please refer to the label on the product or visit
www.sunpower.com.tw for newly update data.
Protection:
1. Short circuit protection: When circuit shorted, power supply will shutdown. After
short circuit has been removed, power supply will recover automatically.
2. Over load protection: When over loaded, power supply will shutdown. After load
reduced to meet rated range, power supply will recover automatically.
3. Over voltage protection: When output voltage exceeds rated range, power will
shut down. After voltage reduced to meet rated range, it will recover automatically.
4. Input polarity reverse protection: SDS-030 series only.
To Parallel Switching Power Supplies
Adjusting output voltage of each power supply to a same level, and then serialize a
diode after the positive pole of each power supply. The diode must be able to carry
current that higher than power supply's max output, and should be equipped with a
proper heat sink. (It is suggested to choose a power supply which max output
could meet your system's requirement instead of paralleling lower output power
supplies)

Wiring:
1. Output wiring must be thick and short enough to carry loading. The shorter and
thicker the wire, the less voltage it drops (less wire loss).
2. Connecting the PE of power supply to system's chassis with a short & thick wire
can reduce noise and prevent electric shock.

Mounting:
1. Each power supply is enclosed with mounting screws. It is suggested to use
enclosed screws to setup power supply, otherwise, make sure its length must not
be too long (refer to the following drawing) to cause short circuit.
2. The input wiring should be separated from output wiring to avoid noise interfere.
3. When multiple power supplies work together, be sure to keep proper distance
between power supply & power supply as well as power supply and the
environment for good air convection. Use extra cooling fans if needed.
