Ripple Noise
*
This is the value that measured on measuring board with capaci-
tor of 22
μ
F at 150mm from output connector.
Measured by 20MHz oscilloscope or Ripple-Noise meter (Equivalent
to KEISOKU-GIKEN:RM-103).

-J (LFA300F)
-
Option -J units, the input and output connector are changed to
EP connectors (Mfr. Tyco Electronics).
-
The appearance in option -J units is defferent from the standard
untis. Please contact us about the detail.
¿
-J1
-
Option -J1 units, the Input and Output connector is VH connec-
tors (Mfr. J.S.T.).
-
LFA300F appearance of option -J units is defferent from the
standard appearance. Please contact us about the detail.

-
-SN
-
-S indicates a type with chassis, and -SN indicates a type with
chassis and cover (Refer to external view). Refer to “Derating
Curves”in Section 3.2.

Please contact us about the detail of LFA300F.
¿
-SNF (LFA300F-5/12/24-TY)
-
In option -SNF, the cover, chassis and cooling fan are added.
-
The appearance of option -J units is defferent from the of stan-
dard appearance. Please contact us about the detail.
-
Oil and other chemical liquid splashing environment may cause
the performance degradation and failure.
¿
-Y
-
Option -Y units can adjust the output voltage by the potentiom-
eter is attached .
-
Refer to the adjustable range to the table 5.2 and table 5.3.

-
To increase an output voltage, turn a built-in potentiometer
clockwise.
-
To decrease the output voltage, turn it counterclockwise.
-
Please take care when you adjust output voltage by potenti-
ometer, because there is possibility of electric shock and the
breakdown as contacting to other internal circui by telectrically
conductive tool.
