SPS series has wide operating temperature
range from -40°C to +85°C.
However, it should be required a enough air flow
for more reliable operation. Output derating
curve provide designers with a quantity of a
current under the desired ambient temperature

If the device is installed in a system, the device’s
temperature of point A should be checked if
does not exceed specified temperature as below.
Please make sure that the ambient temperature
does not exceed 85°C.
*All measurements are taken at the module terminals when
Socketing, place Kelvin connections at module terminals to Point A
Avoid measurement errors due to socket contact resistance

Over current Protection(OCP)
SPS series built in over current protection circuit
Which operates when the output current is over
105% of rating and automatically recovers when
over current condition is removed
If load is connected to a inductive or constant
current load such as lamp of motor, output may
not start up.
Over Voltage Protection(OVP)
SPS series has not built in overvoltage
protection circuit. So, you need to set up a circuit
externally which can protect the over voltage if
necessary.
Soldering Information
The product is intended for through hole
mounting in a PCB, When wave soldering is
used, the temperature on the pins is specified to
maximum 260°C for maximum 10 seconds
when hand soldering, care should be taken to
avoid direct contact between the hot soldering
iron tip and the pins for more than a few
seconds in order to prevent overheating.
