-R

-

You can control output ON/OFF remotely in Option -R models. 

To do so, connect an external DC power supply and apply a 
voltage to a remote ON/OFF connector, which is available as 
option.

1  If the output of an external power supply is within the range 

of 4.5 - 12.5V, you do not need a current limiting resistor R.  If 
the output exceeds 12.5V, however, please connect the cur-
rent limiting resistor R.

To calculate a current limiting resistance value, please use the fol-
lowing equation.

Please wire carefully.  If you wire wrongly, the internal components 
of a unit may be damaged.

The usege is the same as option -R, please refer to Option -R.

-

Reducing standby power is possible by OFF signal of the re-

mote control.

-

Start up time by ON signal in remote control is 350ms(typ).

-

The latch condition in overvoltage protection is removed by tog-

gling ON/OFF signal of remote control.

-

Constant current mode for battery charging is possible by set-

ting the over current activation point within rated output current.

-

Over current activation point varies depending on output voltage 

setting as shown in Table 6.2.

6.2 Others

¡

This power supply is the rugged PCB type. Do not drop conduc-
tive objects in the power supply.

¡

At light load, there remains high voltage inside the power supply 
for a few minutes after power OFF.
So, at maintenance, take care about electric shock.

¡

This power supply is manufactured by SMD technology. The 

stress to PCB like twisting or bending causes the defect of the 
unit, so handle the unit with care.

-

Tighten all the screws in the screw hole. 

-

Install it so that PCB may become parallel to the clamp face. 

-

Avoid the impact such as drops.

¡

While turning on the electricity, and for a while after turning off, 
please don’t touch the inside of a power supply because there are 
some hot parts in that.

¡

When a mass capacitor is connected with the output terminal  (load 
side), the output might become the stop or an unstable operation. 
Please contact us for details when you connect the capacitor.
