APA04 Non-Isolated Power SIPs
3.3V Input, 5V Output
Input Characteristics
The APA04 non-isolated boost power module has no internal fuse. An external fuse
must always be employed! To meet international safety requirements, an input line fuse
should be used. Input wires and copper coil
must be capable of conducting a current of 1.5
times the value of the fuse. If one of the input
lines is connected to chassis ground, then the
fuse must be placed in the other input line.
A fuse with ratings of 20A is recommended for
APA04 non-isolated boost series.
Safety Considerations
For safety-agency approval of the system in
which the power module is used, the power
module must be installed in compliance with the
spacing and separation requirements of the
end-use safety agency standard, i.e., UL1950,
CSA C22.2 No. 950-95, and VDE 0805
(EN60950, IEC950).
For the module's output to be considered meeting the requirements of safety extra-low voltage
(SELV), one of the following must be true:
1 All inputs are SELV and floating, with the output also floating.
2 All inputs are SELV and grounded, with the
output also grounded.
3 Any non-SELV input must be provided with
reinforced from any other hazardous voltages,
including the ac mains, and must have a SELV
reliability test performed on it in combination
with the converters. Inputs must meet SELV
requirements.
If the input meets extra-low voltage (ELV)
requirements, then the converter's output is
considered ELV.

The input to these units is to be provided with a
maximum 20A normal blow fuse in the
ungrounded lead.
APA04 Mechanical
Considerations
Thermal Performance
APA04 non-isolated module can work properly
under natural convection in ambient temperature up to 30°C. If air-flow is applied, it can work
in a much wider temperature range( See derating curves for reference ). In order to maintain
efficient heat dissipation, the converters should
be mounted parallel with the air-flow direction.
Soldering
APA04 non-isolated converter is compatible
with standard wave soldering techniques.
When wave soldering, the converter pins
should be preheated for 20-30 seconds at
110° C, and wave soldered at 260°C for less
than 10 seconds.
When hand soldering, the iron temperature
should be maintained at 425°C and applied to
the converter pins for less than 5 seconds.
Longer exposure can cause internal damage to
the converter. Cleaning can be performed with
cleaning solvent IPA or with water.
