【Instruction Manual】
Before using the Power Supply Unit
Pay attention to all warnings and cautions before using the PSU.
Incorrect usage could lead to an electrical shock, damage to the PSU or a fire hazard.
★Warning & Caution
・Do not modify and remove the cover.
・If any failure or trouble occurs because of utilizing the power supply unit without reflecting the
described contents on this specification, Murata cannot assure such trouble.
・Do not touch the internal components, they may have high voltage or high temperature.
You may get electrical shock or burned.
・Definitely avoid to use the power supply unit by the excessive input voltage, output voltage,
output current and ambient temperature as defined on this specification.
The excessive current, voltage and temperature will cause the deterioration of the components
or abnormal heat, both of which may affect not only to shorten the unit's life-long but also to
damage and break the unit.
・Use the PSU after confirm the correct connection of input and output.
・Be sure not to scratch and damage the input leads. Never transfer the unit by holding
and pulling any lead wire.
・If PSU is dropped, absolutely not to use it any more.
・Make sure not to install and/or store the unit under the environment as stated below because
such will cause the insulation deterioration.
① Make
M k sure to
t avoid
id storing
t i the
th unitit under

humidity or direct sunlight which are out of the standard on this specification.
② Ambient air containing the corrosive gas. (Cl2, H2S, NH3, SO2, NOX, etc.)
③ Places which have the fear to be splashed with water, oil, organic solvent, etc.
④ Places with a high concentration of dusty places.
⑤ Other environment correspondingly mentioned above.
・Make sure not to install and/or store the unit under the environment as stated below
because such will cause the insulation deterioration.
① If any alien substance attached on terminals, it may cause the contact failure or
insertion deterioration.
② The use of the silicon rubber or silicon bond which contain a high percentage of
dimethylpolysiloxane may cause to trigger the contact failure of volume,
potentiometer volume or switch. Make sure to use such rubber or bond with the
percentage of dimethylpolysiloxane 0.1% or less.
・PSU can not be used under the condition of the series operation.
・Rust may occur in the chassis because of use environment.
・This specification regulates the quality of the power unit, if nothing specially defined. When
using the power supply unit, make sure to evaluate and confirm the quality upon mounting
the power supply unit to your product.

【Mounting】
Mounting method
・Please use the place at 50℃ or less around the PSU ambient.
・Please connect the thick and short wire to the FG terminal for safety and EMI.
・Please separate Input wire and Output wire surely.
・Please refer as follows about the Wire for input and output.
AC-intput wire:φ0.8-1.6mm,0.5-2.5m㎡ single wire (Strip length 9-10mm)
LED Output wire:φ0.8-1.2mm,0.5-1.5m㎡ single wire (Strip length 9-10mm)
・Please fix a screw about the installation of the power supply.
(more than two places in total) (Screw hole:φ3.5×4、Φ4.5×2)
【Parallel Operation】
・Series Operation is not possible.
・For parallel operation,
operation either method (1) or (2) is possible.
possible But please caution as follows.
follows
Parallel 1:In a case of operating the plural LEDs for one power supply.
If LED Vf voltage are different, the current may be partial.
Please add a balance circuit not to become so.
