Condition to meet EMC, Isolation, Withstand Voltage and Cooling.
(1) This series is convection cooling type. In consideration of the heat radiation and safety, please keep a distance of
more than 15mm between the power supply and the peripheral parts. When lining up multiple units, please make sure
to place them 15mm or more apart from each other.
(2) Keep more than 4mm space from the top of components to meet safety requirement. If the space is not enough, the
specification of isolation and withstand voltage will not be satisfied.
(3) More space may be required in the surrounding of power supply and the upper area of components for effective
cooling depends on the application conditions.
(4) For installation in Class I end equipment only,
terminal (Protective Earth) must be connected to the earth terminal of the
equipment. All equipment ideally should be mounted inside an earthed shielded metal box. Alternatively an earthed
metal plate can be used to mount the power supply and load to ensure the EMI and EMC performance.
7-3-4. Mounting method for /P model
/P model is optional model with solderable-pin type Input and Output connectors, which should be fixed on PCB of the
end products by soldering.
8. EMC and Wiring Method
This power supply is primarily designed and manufactured to be used and enclosed in other equipment. The installation,
wiring, grounding and end application of the switching power supply in the equipment system may influence its EMC
characteristics. Therefore, the EMC performance has to be tested on end system level. Additional filtering may be
required depends on application and installation methods.
Please refer to following application notes which may help to improve EMC performance.
(1) The output load line and input line shall be separated each other and twisted individually to improve noise.
(2) Use all lines as thick and short as possible to make lower impedance.
(3) Noise can be reduced by attaching a capacitor to the load terminals.
(4) For safety and EMI considerations, connect
(Protective Earth) terminal to Frame Ground terminal of equipment
firmly.
9. External Fuse Rating
Refer to the following fuse rating when selecting the external fuses that are to be used on input line. Surge current flows
when line turns on. Have to use slow-blow or time-lag type fuse, not fast-blow fuse. Fuse rating is considered by in-rush
current value at line turn-on. Do not select the fuse according to input current (RMS.) values under the actual load
condition.
