PAQ65D SERIES Instruction Manual 

1. Terminal  Descriptions

Be sure to take note of precautions and warnings indicated in 
this manual when using this product. Improper usage may lead 
to electric shock or fire. Be sure to read this instruction manual 
thoroughly before using this product.

 

Caution

● There  are  high  voltage  and  high  temperature  components 

within this product. Refrain from disassembling this product 
or touching its internal components as this may lead to elec-
tric shock or burned.

● When the unit is operating, keep your hands and face away 

from the unit. You may get injured by accident.

● Confirm connections to input/output terminals and signal ter-

minals are correct as indicated in the instruction manual.

● Attach  a  fast  blow  type  external  fuse  to  each  module  to 

ensure safety operation and compliance to each safety stan-
dard approval.

● This power module is designed for professional installation 

within the end user equipment.

● Use  isolated  voltage  by  reinforced  or  double  insulation  as 

input power source.

● Do not inject abnormal voltage to output terminal and signal 

terminal from the outside.

● The  injection  of  reverse  voltage  or  over  voltage  exceed-

ing nominal output voltage to output terminals might cause   
damage to internal output capacitor (Functional Polymerized 
Capacitor).

● The application circuits and their parameter are for reference 

only. Be sure to verify effectiveness of application circuits 
and their parameters before finalizing circuit design.

● The information in this document is subject to change with-

out prior notice. For actual design-in, please refer to the lat-
est publications of data sheet, etc., for the most up-to date 
specifications of the unit.

● No part of this document may be copied or reproduced in 

any  form,  or  by  any  mean  without  prior  written  consent  of 
Densei-Lambda.

Note:CE Marking

CE Marking, when applied to a product covered by instruction 
manual,  indicates  compliance  with  the  low  voltage  directive 
which complies with EN60950
