Now... this is a -40C certified switcher from TDK Lambda:
https://www.digikey.com/product-detail/en/tdk-lambda-americas-inc/HWS150-15-HD/285-1299-ND/1631480

Conformally coated circuit boards, Nichicon capacitors, and I know...
it's 8x or 10x the cost at $148.
I'm always open to suggestions from knowledgeable people, and what you say makes some sense.

OTOH, Roland posted here that the Mean Well supplies work with A-P mounts, and I assume that means outdoors under varying conditions.

Mine is in the observatory still pumping 15 watts into a resistor box after 10 hours, and the temp is 33F and 74% RH. I'll be interested to measure the voltage tomorrow morning after 24 hours.

Lambda has a solid reputation, and the datasheet on that supply looks good. I might just spring for the additional cost to put my mind at ease.

Thanks for the link.

Re: APCC Standard Upgrading

Ray Gralak
 

Hi Jack,

You do not need to uninstall the old version. The installer always installs over the old version. However, v1.7.1.0 was released months ago, not within the last month. It could be something specific to your computer, like no permission to write over the old version.

Subject: [ap-gto] APCC Standard Upgrading

I just tried using APCC Standard for the first time in a month, after returning from a vacation. I was prompted to
upgrade to V1.7.1.0, I downloaded the file, closed APCC, ran the installation for the current version. It said it was
installed and when I went to run APCC, it defaulted to the prior version. I was asked to upgrade again.

What's going on?

Do I have to fully remove the prior version and start with a fresh installation of APCC Standard?

Re: Mean Well power supply question - closing the loop

Mike C
 

I would have a cover over the top to prevent frost and dew from settling into that open frame. Be warned you are hanging your GTOCP off a lowest price point Chinese made SMPS. Just looking at the PCB design and parts in it is cringeworthy. It is one thing to have a $200 television inside a constant environment house with these cheap switchers but I would never do it to a GTOCP outside in wildly swinging humidity and temps.

Now... this is a -40C certified switcher from TDK Lambda:
Conformally coated circuit boards, Nichicon capacitors, and I know... it's 8x or 10x the cost at $148.

Re: Default.mlm file recovery #APCC

Ray Gralak
 

Hi Claude,

 

APCC automatically saves all settings in compressed files in this folder:

 

C:\ProgramData\Astro-Physics\APCC\Backups

 

Each filename has the date/time in the filename. For example, this settings file indicates the date was 2018, December 10th, 15:34:52 local time (about 3:34 PM):

 

ApccZ-Settings-Backup-2018-12-10-153452.ApccZ

 

From APCC, you can restore any settings file which includes default.mlm from APCC's File menu with the "Load Settings" menu item as shown here:

 

 

BTW, the ApccZ files are just zip container files. If you rename the file extention from “ApccZ” to “Zip” you should be able to open them directly in Windows explorer. However I recommend you use APCC to load the settings so that the files will be placed in the correct folder locations.

I've been watching for the release of public updates to the AP ASCOM v2 driver and the keypad software as indicators.  It is my understanding that new versions of both will be released which will work with the Mach2.


Re: AP 92mm and NiteCrawler - Even Possible?

Well you could thread one on, but I am not really sure why one would want to do that. The NiteCrawler weights like 5 times the scope. :)

Re: Mean Well power supply question

Joe Zeglinski
 

Mike,

Good idea about "isolating " your Mean Well power supply with wood and a plastic enclosure, so you no longer (?) have a leaky ground return to the GFCI, from it.

If the "Euro Safety Regulations", as recently noted by Rolando, require tying power supply DC Returns to chassis/earth ground - dumb idea, unsafe for electronics even with a nearby storm just miles away - and the chassis ground on the 120 AC side of the power supply case and power cord's earth return (third pin) is also tied to house neutral in the fuse box through plumbing or copper ground rod, then why wouldn't the GFCI not trip, when it senses even a few milliamps, (or perhaps just micro amps), supplied by the CPx controller's serial port housing? That's true for many other controllers anywhere on the scope besides just AP's). In such case, the (slightly) leaky chassis ground return is tied to the GFCI circuit protected socket.

The GFCI would naturally trip to protect you from being (potentially) electrocuted by electronics with a chassis ground tied to the pier.
Seems logical. Probably nothing you can do to prevent it, except replace the GFCI outlet for the pier, with a non-fused one. However, your home fuse box panel might also be wired with GFCI breakers. It probably isn't, or you would have a room full of lights drop out every time you power up the telescope electronics, using a normal outlet. GFCI breakers are very sensitive, if they do their job right.

You can likely prove the possibility of the pier chassis leaking current to your GFCI protected AC power cord, supplying your telescope. Using an ohmmeter , check the resistance (continuity) between scope electrical system and GFCI supply - on the unpowered telescope - by touching the probe to the bare serial port screw on the CPx, and the other probe to the earth safety ground pin in the AC socket at the telescope. A meter with a "continuity buzzer" would be easier to use than looking at a reading.

A few milliamps of chassis current won't hurt you, but it is reassuring that the GFCI would protect you from a major short circuit from something at the pier. But, the GFCI can be a nuisance for typically minor amps from pier equipment.

Joe Z.

No; the one that tripped was the one powering the pier equipment, so
that's the one I tested.

No matter. I have the Mean Well mounted on a board, and enclosed on
three sides with a plastic shield that extends over the ends, so I'm
ready to use that one.

Default.mlm file recovery #APCC

Claude Benoit
 

Does the Default.mlm file have pre-defined meridian limits? I saved new meridian limits on my installed default.mlm file by accident. If default.mlm has pre-defined limits I'd like to restore them. I moved the overwritten default.mlm file to another directory then re-installed APCC but the new default.mlm file wasn't in it's directory. 

Thanks
Claude
