Wiring Method - TDK-Lambda SWS-L Series Manual

SWS
600L, 1000L
(1) The output load line and input line shall be separated to
improve noise sensitivity.
(2) The sensing lines shall be twisted and separated from the
output lines for remote sensing.
(3) Use all lines as thick and short as possible to make lower
impedance, clamping core at both input and output wires
benefi t EMI performance.
(4) Attaching a capacitor to the load terminals can eliminate noise.
(5) For safety and EMI considerations, connect terminal to the
mounting set ground terminal, power supply and load mount-
ing on aluminum plate is recommended for EMI setting.
(6) Recommended torque for the terminal :
SWS600L Input terminal (M4 screw)
Output terminal (M5 screw)
SWS1000L Input terminal (M4 screw)
Output terminal (M8 bolt & nut) : 10.8 N · m (110kgf · cm)
(M4 screw)
[The PHD connector manufacture method]
This product is using SPHD-001T-P0.5 or SPHD-002T-0.5 connec-
tor made from JAPAN SOLDERLESS TERMINAL MFG CO LTD.
Regarding to manufacture of a connector, it becomes the
regulation as following.
a). Appricable Wire and Crimping tool
Wire size is AWG#26 - AWG#22 and insulation outer dia is
- φ1.5 mm.
Appreciable wire per barrel size is UL1007 (standard wire)
and its equivalent standard wire can be used. Regarding the
AWG#22, use UL1061 or its equivalent standard wire, because
wire insulation outer diameter of UL1061 is small.
Crimping tool is as below.
Crimping tool Crimping applicator
AP-K2 or AP-KS MKS-LS-10 or MKS-L-10 SPHD-001-05/SPHD-002-05
b). Crimping Operation
The reference value of wire strip is 2.3mm. As wire strip length dif-
fers depending on type of wire and crimping method, decide the
best wire strip length considering processing condition. When
wire is stripped, do not damage or cut off wire conductors.

Note1. Crimp height at wire barrel should be set to pre-determined
dimensions.
Note2. Adjust crimp height at wire insulation barrel to the extent
that wire insulation is slightly pressed, and set it so that
crimping is not excessivery.
Note3. Crimping condition at wire insulation barrel is as below Fig.1.
Note4. For AWG#28, #26, #24, use UL1007 type. For AWG#22,
use UL1061 type.

c). Inserting contact into housing
Inserting crimped contact into housing
(1) Do not apply any pulling force to crimped part, and insert
contact parallel to housing.
(2) Insert contact into housing without stopping to innermost.
(3) Check secure locking per each insertion by pulling wire softly
in order to check that contact does not come off housing. Be-
sides, check whether there is the backlash in the direction of
insertion axis.

d). Mating and Unmating Connector
(1) Inserting connector
Hold receptacle housing securely and insert into header
straight against to header post until click sounds.
(2) Unmating connector
Hold all wires securely and fi x receptacle housing by fi n-
gers so as to pry, and then, withdraw it on the mating axis.

e). Routing of Wire
Routing wire so as not to apply external force to connector ex-
cept force to such an extent that wire slightly buckles, consider-
ing an enough length to route and fi xing of wire.
