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.
  In a case of LED VF 30V or less because of LED chip dispersion, please make sure to evaluate
and confirm the quality upon mounting the power supply unit to your product.

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
