Re: [Elecraft] Battery Charging with DC Power Supply

Hi Steve, My experience has been better with the IOTA DLS-45. I used it for about a year for my Icom 746pro. Then I bought an Alico DM-340MV linear for my 746pro and used the IOTA for my 2m radio. I did not notice any difference in noise levels on HF - but perhaps it depends what frequenci

Re: [Elecraft] Battery Charging with DC Power Supply

Sorry, guess that term wasn't real clear. A power supply doesn't control the charge rate, it controls the output voltage. Most bulk storage batteries don't want to charge at high rates, say over 0.5C, although you can probably get away with it for a time. Controlling the charge rate generally im

Re: [Elecraft] Battery Charging with DC Power Supply

Hi All, Just a note on the Iota DLS-30/IQ4 that I have. I originally purchased it because I thought that I could also use it as a power supply as it is advertised. As it turns out I can not use my Elecraft K2 while it is plugged in charging a battery. The RFI is very great on 80 meters up to I t

Re: [Elecraft] Battery Charging with DC Power Supply

Tnx Wes! So the battery voltage across the power supply terminals keeps the SCR turned on, even though the supply voltage is turned off by the crowbar. That would surely lead to a dead SCR without a suitable fuse in the battery circuit. Ron AC7AC Since Astron has been men

I'm not quite sure what is meant by the term 'uncontrolled source'. A regulated power supply makes a fine battery charger. Review the charging recommendations at the various battery manufacturer sites such as here: or here:

Re: [Elecraft] Battery Charging with DC Power Supply

I just have to chime in on this one. I run my K3/100-based station on solar photovoltaic power, with a 100 AH SLA battery for storage. Quick description of this installation is that I use a charge controller to regulate battery charging. It's a Micro M+ c/c and can put out 4A for a 12VDC system.
