Wiring Method - TDK-Lambda ZWS-BP Series Instruction Manual

■Condition to meet Isolation & Withstand Voltage standard.
Keep 4mm space from the surfaces and sides of PCB. Especially,
8mm space is necessary from the solder surface.
If the space is not enough, the specification of isolation and
withstand will not be satisfied.
Take the space in the power supply surroundings and the upper area of
components to keep enough for convection cooling.

should be connected to the protective earth terminal of the equipment. Also 2 mounting holes are should be connected to
the Chassis (Conductor) by metal spacer. If not, the conducted noise, radiation noise and output noise will increase.

8. Wiring Method

(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 made lower impedance.
(3) Noise can be reduced by attaching a capacitor to the load terminals.
(4) For safety and EMI considerations, connect between
9. The life expectancy
The life of the power supply depends on the life of the built-in aluminum electrolytic capacitor. The life is described in reliability data.
The life of the aluminum electrolytic capacitor varies depending on the method of mounting the power supply, the load current, and the
ambient temperature. Please refer to "Electrolytic Capacitor Lifetime".
Please do not use the product which passed over the life expectancy. There is a risk of unexpected output shutdown and specifications may
not be satisfied.
Please contact us for maintenance or exchange the product which passed over the life expectancy.
