Hallo,

Ich habe ein problem mit mein ALC60 systeme. Können Sie mich helfen am "Laserforum English"?
Ich schreibe nich gut Deutsch, aber ich ferstehe! <img border="0" title="" alt="[L&auml;cheln]" src="images/icons/smile.gif" />

Gruss,

I have a problem with my ALC60 system. When I turn up the "power", the beam intensity is not stable. It oscillates. Up to 10A is it no problem, but 10-12A it is oscillating VERY much.

I put my oscilloscope probe on the current measurement connectors (red and black 4mm connectors) on the ALC 60 ...

To adjust the tube current, you adjust the PWM to the ferrite core. Question: Between which voltages (approx.) do you control the tube current?<p>If the PWM goes too low, I assume the ionazion disappear.<p>Best regards,
Magnus

BTW, how critical is the filament voltage? I have read that the voltage should be 3.2V. On another site I read 5V. <p>Magnus

Hi,<p>Well, no I don't use a variac. I had the schematics of a linear PSU of the ALC60 from www.laserfaq.com in front of me, when I wrote the reply. But the PSA12 use a 15kg transformer. That is just like a variac, but with no wiper. So, -it still got the weight! :-(<p>I mean that I will use the ...

Hello Ralf,<p>What are the problem with your SMPSU?
I have some questions about it:<p>1. Are the "filament transformer" outside the PCB? It isn't in the ETD49 core?<p>2. Do you use the ETD59 in "push-pull" (primary has three terminals and at least two transistors) mode or "feed-forward" (primary ...

Hi,<p>Sorry about the mistake in the calculation. I saw the mistake just when I pressed "post reply", but I was unable to delete/edit the reply.<p>I don't have a working SMPSU for my argon laser yet. Sorry if I gave you that impression. I use MediaLas PSA12 now. That is a 20kg piece, and I don't ...

Hi laserists,<P>I dislike the high fan noise of the ALC60. It is the original with "air-tunnel". When I use it to try out new animations, I run at minimum power. The fan speed is the same whatever I set the optical power to. The air temperature is 65 degrees. When I turn up the optical power it is ...

To make special voltages like the -5.2 volt there are no regulators made for this, but if you don´t need too much power, use an op-amp! <P>1. Connect +/-15V to supply the op-amp. <BR>2. Connect the negative input (-) to the output. <BR>3. Connect a voltage divider that makes -5.2V (f.x 5k6 and 10k ...

If you don´t add +1026 and +1024 to the base address you will still use SPI mode, -even if the BIOS is in ECP mode. By adding +1026/+1024 it tells the parallel<BR>I/O chip to use ECP mode. <P>Note that you must set BOTH the BIOS and the software code (the one you replied with) to ECP mode to get it ...

It is very easy! <P>1. Set the BIOS to ECP mode, DMA disable. <BR>2. out 632+1026,64+32 (632 is for LPT2 $278) <BR>3. out 632+1024,byte <P>Now, when you enter the third row the byte will be at the <BR>parallel port and the strobe will automatically go low. When this byte is read by f.x. a ...

I am successfully using ECP to transfer 16bit @ 56k to my scanner pair. <P>-Has anyone got the DMA to work in ECP mode?
