3. Mounting Method
1) This is convection cooling type power supply. In the consideration for the heat radiation and safety. Please take a
distance 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) The maximum allowable penetration of mounting screws is 6mm.
3) Recommended torque for mounting screw
HWS15A-150A (M3 screw) : 0.49 N×m( 5.0 kgf×cm )
4. Wiring Method
1) Input line shall be separated and twisted to improve noise sensitivity.
2) The sensing lines shall be twisted and separated from the output lines.
3) Use all lines as thick and short as possible to make lower impedance.
4) Noise can be eliminated by attaching a capacitor to the load terminals.
5) For safety and EMI considerations, connect the FG terminal of HWS15A-150A to mounting set ground terminal.

Note 1 : When using separate loads, use of two pcs. of 0.8mm thick crimp-type terminal is recommended.
Note 2 : Select the wire diameter in consideration of the rated current and the current during OCP operation.
For recommended diameter, refer to wire maker recommended allowable current and voltage drop.
Especially, for 3V or 5V models, output current is large. Thick diameter wire is recommended.
Note 3 : Use wires rating at least 90℃(CSA) / 75℃(UL) and copper conductor only.
Note 4 : Use crimp-type terminal for connection to terminal.
5. External Over Current Protection
The following types of fuses that 1.5 times or less the rated current should be connected to the
output of the power supply. And also select to wire diameter according to Note 2 of
"4. Wiring Method".
