May be a smaller knob on one of the larger knobs or separate, and turn like a volume control. It could be set to limit the amount of current the power supply would supply for testing/design applications. jerb At 08:05 AM 3/26/2010, you wrote: >The Power Supply is an Astron RS-35M , 13.8v, 25 amps continuous @ >50% duty cycle.

He probably has not yet received it. However, I look forward to his corroborating my high/non-optimal voltages. So, we shall see. --Jose Read this topic online here: http://forums.matronics.com/viewtopic.php?p=292088#292088 ________________________________ Message 3 _____________________________________ Time: 01:47:15 PM PST US From: "Fisher Paul A." Subject: AeroElectric-List: Voltage measurements for Schumacher 1562A I realize the issue is the new model versus the old version, but I did take some measurements that I wanted to report. I have three of the 1562A's - all of which appear to be the "old version" with the 6V-12V switch on the f ront panel. All of them were purchase from Wal-Mart on two different dates . The last two were purchased in August or September of 2009. SWC0907 SWC0701 SWC0907 Holding voltage 13.33V 13.32V 13.30V Charging voltage 14.39V 14.54V 14.30V The "SWC" numbers were stamped into the bottom of the case - I have no idea if these are relevant or not, but I included it in case it made sense to s omeone. The first charger is connected to a tractor (standard automotive t ype battery), the second and third are in airplanes with RG batteries. Test procedure: After the chargers had been on for over 24 hours, I took r eadings of the holding voltages. Then I turned lights on for 2-3 minutes t o activate the charging. After the voltages stabilized (3-5 minutes), the voltages were recorded again. I'm not sure if this helps anyone or not, but I at least wanted to report w hat I found... Paul A.

I have a PC680 in my plane. I flew for 2.6 hours last Sunday and did not put the charger/maintainer on. Today when I got the airport I first checked the voltage of the battery. 12.83 VDC. All readings were taken at the battery terminals. Next I fired up the 1562A. Initial voltage was 14.2, then very quickly up to 14.9. After about a minute the voltage stabilized at 14.88 VDC. Half hour later 14.86 to 14.87 VDC. Hour one 14.83 to 14.84 VDC. Hour two. Finally reached float at 13.4 to 13.5 VDC. Hour three 13.45 VDC. Test concluded. It appears to my untrained eye that the unit is functioning properly. Bob, please let me know if my assumptions are correct or incorrect. Kevin Boddicker TriQ 200 N7868B 160 hrs Luana, IA.

It is now known as the RHP-520. You can find the users manual on the web and download it as I did. In a brief scan, I saw nothing about the PTT jack or any detail about headset operation. The headset adapter cable I have does not split out a ptt jack The RHP nee RHP is a great little radio IMHO! -------- Ira N224XS Read this topic online here: http://forums.matronics.com/viewtopic.php?p=292139#292139 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message aeroelectric-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/AeroElectric-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/aeroelectric-list Browse Digests http://www.matronics.com/digest/aeroelectric-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
