AC-DC Power Supplies Enclosed Type

External Power

Source

Connector for remote ON/OFF (Optional)

Fig.5.4 Example of use remote ON/OFF

*This connector is different if used with option -J.Refer to Fig. 5.3

for pin arrangements.

¡When external power source is in the range of 4.5 - 12.5V, cur-

rent limit resistance R is not required. However, when external

power source exceeds 12.5V, current limit resistance R must be

connected.

To calculate the current limit resistance, use the following equa-

tion:

Vcc- (1.1+RiX0.005)

R [W] =

0.005

Where ;

Vcc = External Power Source

Ri = The internal resistance (780W)

¡A wrong connection may damage the internal components of the

unit.

¡Remote ON/OFF circuit (RC (+), RC (-) ) is isolated from input,

output and FG.

¿-N1

-A type with a ﬁ tting supporting a dedicated DIN rail.

-Consult us external view in details.

-A type in which terminal block screws are aligned vertically (op-

tion: -T).

Fig. 5.5 Din Rail Attachment

¿-W

(It is not possible to combine with option -J)

--W is available for detecting low input alarm (PF), detecting low

output voltage (LV) and operating N+1 redundancy.

-Alarm speciﬁ cation is shown Table 5.2.

-Special harness is prepared, refer to option parts.

-Consult us external view in details.

-Each alarm (PF,LV) is isolated from input, output and FG.

Alarm

When line voltage is abnor-

mal (low input voltage out of

range), the alarm outputs from

CN3.

If the output voltage drops be-

low the rating, the alarm signal

is output from CN3.

Note : 1This becomes un-

stable in the event

of output overcur-

rent (intermittent

overcurrent).

2The alarm signal is

not output for paral-

lel operation that

does not use OR

diodes.

Please consult us details.
