-R2 (LHA100F, LHA150F, LHA300F)
-
You can control output ON/OFF remotely in Option -R2 units. To
do so, connect an external DC power supply and apply a volt-
age to a remote ON/OFF connector, which is available as op-
tion.
-
Standby power with remote OFF is lower than the one with no
load.

-
Overvoltage protection is reactivated by toggling ON/OFF signal
of remote control. (Only LHA150F, LHA300F)

1 If the output of an external power source (Vcc) is within the
range of 4.5 - 12.5V, you do not need a current limiting resis-
tor R. If the output exceeds 12.5V, however, please connect
the current limiting resistor R.
To calculate a current limiting resistance value, please use the fol-
lowing equation.

Please wire carefully. If the wire incorrect, the internal components
may be damaged.

Remote ON/OFF circuits (RC(+) and RC(-)) are isolated from in-
put, output and FG.

-S indicates a type with chassis.
-
In optional -S case, “Derating”, “Maximum temperature of mea-
surement points”, “Life Expectancy” and “Warranty” is same as
standard model.
-
LHA10F and LHA15F are different from standard models.
Please contact us.

-SN
-
-SN indicates a type with chassis and cover (Refer to external
view).
-
In optional -SN case, please refer to “Derating”. Also “Maximum
temperature of measurement points”, “Life expectancy” and
“Warranty” is different from standard models.
Please refer to Table 6.3 to Table 6.26.
