Specifications

Please do not apply an external voltage of -0.7V or less or 3.0V
or more.
There is more than one method to adjust the output voltage, in-
cluding the methods to use external resistors and external power
supplies. Since each method has different characteristic, please
contact us for details.
¡
If the terminal TRM opens while the external output voltage control
function is in use, a unit generates the rated voltage.
If the terminal VB and the terminal -S are connected and the ter-
minal TRM opens as shown in Fig.2.1, the unit stops generating
the output voltage.
¡
You can change the control voltage of TRM from 0 - 2.75V to 0 -
5.5V by serially connecting 1.73
W
to the TRM terminal as shown
in Fig.2.2.
¡
If the output voltage decreases to almost 0V, a fan may stop, out-
put ripple may become large and PG signals may turn to ”High.”
¡
Please do not change TRM voltage rapidly.
2.7 Remote ON/OFF
¿
PBA10F, PBA15F, PBW15F, PBA30F and
PBW30F
¡
These models do not have a remote ON/OFF function.
¿
PBA50F, PBW50F, PBA75F, PBA100F and
PBA150F
¡
Option -R is available to provide a remote ON/OFF function.
Please see ”7. Options” for details.
¿
PBA300F, PBA600F, PBA1000F, PBA1500F
and PBA1500T
¡
These models have a remote ON/OFF function.
You can operate the remote ON/OFF function by sending signals
to CN1. Please see Table 2.1 for specifi cations and Fig.2.3 for
connecting examples.
¡
Remote ON/OFF circuits (RC2 and RCG) are isolated from input,
output, FG and AUX.
¡
Please note the followings when using the remote ON/OFF func-
tion.
1
The output stops when a current fl ows to RC.
2
The current fl own to RC is a 5mA type (maximum 12mA).
3
If the output voltage is turned off through the remote ON/OFF
circuit, the built-in fan stops.
In the case of PBA300F, the fan slows down when the output
voltage is turned off through the remote ON/OFF circuit.
4
If the output voltage is turned off through the remote ON/OFF
circuit, PG signals turn to ”High.”
5
Description in this section is based on the assumption that you
will use one unit alone. If you are planning to use the units
in parallel operation or use multiple units for a single system,
please check necessary voltage and current values.
6
If voltage or current of a value not listed in Table 2.1 is applied
between RC2 and RCG, the output voltage may not be gener-
ated normally.
2.8 Remote Sensing
¿
PBA10F, PBA15F, PBW15F, PBA30F,
PBW30F, PBA50F, PBW50F and PBA75F

You can also control

through TRM on CN1.
However, we
recommend using TRM
on CN2 just in case
CN1 comes off.
