Title: webswitch used for TS870 power on/off
Post by: yo3irm on 2014-02-16, 22:31:30

Hi,

I would like to use webswitch 1216H to power on/off my Kenwood TS870.
My concern is related to the current drain, in the transceiver documentation it states that the current drain is 20.5A for TX and 2 A for RX.
I see that the webswitch 1216H is rated for 16A, I don't know if it has also a fuse for 16A.

It seems there are many use of this webswitch to power on/off other transceivers and I think all have current drain grater than 16A on TX.

Thanks for any explanation/advice !

Hi

You should not switch the 13.8 V with the webswitch, you should switch the 230V before the Power Supply.

yes, the switch will be between power outlet and the power supply, see picture below how I would like to configure them:

(http://aureliandan.smugmug.com/Other/HamRadio2/i-JS2zMZ2/0/O/microbit.jpg)

So I would like to put one of the webswitch relay on the power extension cord. Is this correct ?

If the transceiver will drain 20 A from the power source, will this current drain be transferred to the power outlet also ?

Thanks

No even if the efficency of the power supply is as low as 50% it will only be 2.5 A at 230 V if the radio consumes 20A at 13,8 V

Nothing against the Webswitch, but wouldn't it be a lot easier and cheaper to buy
an IP power strip? There are many on the market, even below 100 Euros.

There are so many on the market, that it is difficult to recommend any specific one. I am puzzled why
you can't find one.

I have two types in use at my remote stations:

NetIO230A or B: http://www.koukaam.se/kkm/products.php?cat_id=19

Energenie EG-PM2-LAN: http://energenie.com/item.aspx?id=7557

Both are well under 100 Euros in DL, including VAT.
