SEC 1235M operating in 230 VAC

Hello,

while waiting for Samlex answer, maybe someone using a Samlex SEC 1235M can
help me to find the jumper to switch from 120 to 230 VAC?

I bought this PS that was recommended in this list, but really I couldnt
find this jumper to start using it at 230 VAC

thanks,

Jorge

Hello,

some months ago I bought in USA a SEC 1235M, S/N 03435-1032-00003

I am going to use it now with 230 VAC, but I couldn´t find the jumper to
change from 120 VAC to 230 VAC.

Do you have a photo to show me where is it?

thanks,

Jorge

This site :

say's 'internal strap change', that suggests a wire to re-solder.

This is their site:
http://www.samlexamerica.com/products/productdescription.asp?ProductsID=36025

there is a product manual (http://www.samlexamerica.com/customer_support/pdf/Manuals/SEC-1235_SEC-1235M_Manual_Sep2007.pdf) and it says:

These units have been preset to operate from an input voltage of 120 VAC, 60 Hz. The units can be set to operate from an input voltage of 230 VAC, 60 Hz. by changing the position of an internal jumper. The procedure for conversion to input voltage of 230 VAC, 50 Hz. is as follows:
• Switch off the unit and unplug the power cord from the AC outlet • Remove the top cover • For 120 VAC operation (pre-set condition), points "D" and "E" on the
printed circuit board (PCB) have been connected (shorted) with a flexible wire jumper. To convert to 230 VAC input, disconnect the quick disconnect connector at point "D" by pulling it upwards. Tape this end with an insulation tape and use a cable tie to tie it securely to the wire harness running above
• The fuse on the AC side for the preset input voltage of 120 VAC is rated at 250 V, 8 A. For 230 VAC operation, the fuse has to be rated at 250 V, 4A. Replace the existing 8 A fuse with a 4 A fuse. See under “SPECIFICATIONS” on page 11 for details on the 4 A fuse.
•The detachable power cord that is provided has an “IEC 320-13” female connector on one end that will mate with the “IEC 320-C14” male AC inlet connector on the power supply. The other end of this power cord has a 120 VAC NEMA5-15P plug meant for connection to the 120 VAC, NEMA5-15R outlet. For operation on 230 VAC, 50 Hz, a different detachable power cord will have to be used. Use an appropriate power cord that has an “IEC 320-13” female connector on one end (for connection to the “IEC 320-C14” AC inlet connector on the power supply) and a 230 VAC plug on the other end corresponding to the 230 VAC outlet. Please ensure that the new 230 VAC power cord uses two pole, 3 wire grounding configuration (this will ensure proper earth grounding).

WARNING ! The unit has been pre-set to operate from an input voltage of 120 VAC. Hence, before plugging the unit to the AC outlet, please ensure that the local AC power supply voltage is 120 VAC. Operation from 230 VAC is possible by changing internal settings. Please see details on page 3 under “OPERATION FROM AC INPUT VOLTAGE OF

Re: SEC 1235M operating in 230 VAC

thanks David and Ken,

I am reading the manual, just that is difficult for me to find this jumper.
I asked Samlex for a diagram or photo to show where it´s located.

If you do that, maybe you know where is it.

Page 4 of the manual available online
has detailed instructions for "OPERATION
FROM AC VOLTAGE OF 230 VAC".
~~~~~~~~~~~~~~~~~~~
These units have been preset to operate
from an input voltage of 120 VAC, 60
Hz. The units can be set to operate from
an input voltage of 230 VAC, 60 Hz. by
changing the position of an internal
jumper. The procedure for conversion to
input voltage of 230 VAC, 50 Hz. is as
follows:
. Switch off the unit and unplug the
power cord from the AC outlet
. Remove the top cover
. For 120 VAC operation (pre-set
condition), points "D" and "E" on the
printed circuit board (PCB) have been
connected (shorted) with a flexible wire
jumper. To convert to 230 VAC input,
disconnect the quick disconnect connector
at point "D" by pulling it upwards. Tape
this end with an insulation tape and use
a cable tie to tie it securely to the
wire harness running above
. The fuse on the AC side for the preset
input voltage of 120 VAC is
rated at 250 V, 8 A. For 230 VAC
operation, the fuse has to be rated at
250 V,
4A. Replace the existing 8 A fuse with a
4 A fuse. See under "SPECIFICATIONS"
on page 11 for details on the 4 A fuse.
.The detachable power cord that is
provided has an "IEC 320-13"
female connector on one end that will
mate with the "IEC 320-C14" male AC
inlet connector on the power supply. The
other end of this power cord has a 120
VAC NEMA5-15P plug meant for connection
to the 120 VAC, NEMA5-15R outlet.
For operation on 230 VAC, 50 Hz, a
different detachable power cord will have to
be used. Use an appropriate power cord
that has an "IEC 320-13" female
connector on one end (for connection to
the "IEC 320-C14" AC inlet connector

on the other end corresponding to the

The website of our late friend Tom still has a couple of articles on this
power supply which may help. See

Re: SEC 1235M operating in 230 VAC

it´s a yellow cable near the fan.

You need to move some wires to be able to see the "C" and "D" described in
the manual.
