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. 73, Jorge CX6VM -----Mensaje original----- De: David Ferrington, M0XDF [mailto:[email protected]] Enviado el: Viernes, 09 de Septiembre de 2011 10:59 a.m. Para: Jorge Diez - CX6VM CC: [email protected] Asunto: Re: [Elecraft] SEC 1235M operating in 230 VAC This site : http://www.radiodan.com/pdf/SEC1235M_Review.pdf say's 'internal strap change', that suggests a wire to re-solder. This is their site: http://www.samlexamerica.com/products/productdescription.asp?ProductsID=3602 5 there is a product manual (http://www.samlexamerica.com/customer_support/pdf/Manuals/SEC-1235_SEC-1235 M_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). 3. FEATURES OPERATION FROM AC INPUT VOLTAGE OF 230 VAC CONNECTION AND OPERATION 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 230 VAC -- The rung of a ladder was never meant to rest upon, but only to hold a man's foot long enough to enable him to put the other somewhat higher. -Thomas Henry Huxley, biologist and writer (1825-1995) On 9 Sep 2011, at 14:42, Jorge Diez - CX6VM wrote: > 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 > > CX6VM > > k3 #4077 > > > > De: Jorge Diez - CX6VM [mailto:[email protected]] > Enviado el: Jueves, 08 de Septiembre de 2011 08:33 p.m. > Para: '[email protected]' > Asunto: SEC 1235M operating in 230 VAC > > > > 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 > > CX6VM > > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:[email protected] > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
