Operation

Remote Sensing Function

The remote sensing function makes it possible to compensate for

voltage drops caused by load lines. To use this function, remove the

short bar from the remote sensing terminals and wire the Power

Supply and load as shown in the following illustration. The remote

sensing terminals are short-circuited with the short bar before ship-

ping.

Note:

1. When the voltage drop in the load wiring is large, the

overvoltage protection function might engage just from

the increase in voltage to correct the voltage drop, so be

sure to use high capacity wiring.

2. If the remote sensing terminals are left unconnected, the

high voltage protection function will engage and the out-

put voltage will be cut off. Be sure to firmly tighten the ter-

minal screws.

Remote Control Function

The remote control function enables external signals to turn the out-

put of the Power Supply ON and OFF. To use this function, remove

the short bar from the remote control terminals and connect a switch

or transistor to the Power Supply as shown in the following illustra-

tion. The remote control terminals are short-circuited with the short

bar before shipping.

Note:

No output will be produced if the terminals are left uncon-

nected. Be sure to firmly tighten the terminal screws.

Fan Alarm Function

(300- and 600-W Models Only)

When the speed of the internal fan drops, the fan alarm output

(SPST-NO) will turn ON (shorted) and after 5 seconds, the output

voltage will be turned off.

The relay contacts must be used with 1 A at 30 V or 1 A (125 VA) at

250 VAC.
