I wanted to stick the folowing up, to be of assistance-

just a quick note to bring your attention to the facts about using power generators in conjunction with our dye-sub printers.

If you use of a dye-sub printer in the field via a power generator, please bear in mind-

1. Printers should always be used with a stabilized power supply!
2. The ideal scenario is to have a current monitoring UPS between the generator and the printer.
3. They have to consult before using a power generator and do an extensive study on the specs of the generator.

Ignoring the above three, may cause a severe damage to printers, which is not covered by the warranty!!!

Well, I am not in a position to advise, or suggest generators, sorry.

I am sure that EPS members will gather on this one.

We always use a UPS between the generator and printers. For the sake of 100 for a UPS it's well worth the investment to save your dye-sub's.
In my early days I found out the expensive way as to what happens if you don't use the correct generator. Bear in mind that a surge protector may save you if there's a surge in power but not if there's a dip in power, and that can have just as bad an effect.
Also by using a UPS it means you don't lose power if your generator runs out of fuel, you've got a good half hour to get your genny topped up and running again.
If you're using a UPS the type of genny you use won't be quite so important, although the Honda suitcase generator is recomended by a lot of people, and I use a replica brand of this similar to the Kippor one with no trouble at all (half the price of the honda one too).

Andrew can you point me in the right direction "Link Wise"
would appreciate it
Many Thanks

I use a UPS like this:
http://www.amazon.co.uk/Trust-1300VA-Ma ... 897&sr=1-2 (http://www.amazon.co.uk/Trust-1300VA-Management-UPS-PW-4130M/dp/B0012RW21A/ref=sr_1_2?ie=UTF8&s=electronics&qid=1277159897&sr=1-2)

and a generator like this:
http://cgi.ebay.co.uk/ws/eBayISAPI.dll? ... K:MEWNX:IT (http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=150440113164&ssPageName=STRK:MEWNX:IT)

The generator has a digital inverter so probably doesn't actually need a UPS, but like I said, may as well be safe and it does give power while you top up the fuel on the genny.

Following on from Andrew's UPS solution.

Can you find a cheaper genny than the one I have just tripped across.

you can pick them up from their depot for 140
based in wickford,is that essex area !
will charge a 12v battery

Regarding KMS, having visited their depot out of necessity as I needed a Kipor generator urgently, my recommendation would be to pay the delivery charge.

It is a very large warehouse at the end of a farm track, the location of which they only grudgingly reveal. Customer service skills are non-existent. Do you want me to go on?

Pay the delivery charge and save yourself the grief. Or better still choose an alternate supplier of the generator as I know they do not have sole supplier status.

i used a genny like that for 4 events back in 04 - before it blew up 2 pc's when powering kit down at the end of the day and caused a surge protector to melt

i just bought one of these and also a trust 1300 UPS
just wondering if you have had any success with it.
I can run anything from it directly but the minute i put a UPS in the equation the UPS goes straight to battery power so clearly it doesn;t like the output forn the genny?
be interested to know if you have had same experience or if anyone has any suggestions (yes i know buy a kipor!).

Andy, I'm sure someone here will want to correct me, but my understanding is that the ups battery runs the printers (or whatever is plugged into it) and the genny charges the battery (at the same time) so this means it's actually doing it's job. That's how it gives you a constant power supply. In other words, don't worry it's fine.

Mark Ratcliffe
30-06-2010, 04:44 PM
As Andrew says its working fine,your genny powers the battery,im guessing it has to juice up the battery's initially, then battery powers your kit,if your power via genny goes, your ups battery will still run your kit,not for long !,fill up with petrol etc,i have run this genny for 8 hours with out having to fill up,

hmmm my ups goes straight to battery power when i fire up the genny and i keep losing coms from ups to lap top to see what is going on
odd

im sure you aware,switch on the most power hungry item first ,work your way up
i power each item up as so
1st,PC
2nd,Printer
3rd ,PC Monitor
4th Wyse terminals,1 at a time
5th Viewing monitors 1 at a time
And reverse when powering down
allows genny not to stress on power up,and to dump excess power as you switch off spk

andycampbell
30-06-2010, 05:06 PM
it just goes straight to battery when connected to genny supply without connecting anything!
behavces fine when plugged in to mains so has to be genny

Mark Ratcliffe
30-06-2010, 05:21 PM
:?:
have you run anything directly off the genny,a drill or something similar,or a Fan,if it powers these then im at a loss,
:?: Nothing connected to 12v outlet out of genny,Just from 240v connector,you have set it to 240v not 120v etc
i know you will have but sometimes when i panic,i dont sit back and check everything,i spent 5 minutes swearing at it ,because it wouldnt start,sat down ,had a look realised not swithed power button ON !

Mark Ratcliffe
30-06-2010, 05:22 PM

andycampbell
30-06-2010, 05:52 PM

Just spoke to a sparky mate of mine that says it could be that the surge protection circuit of the UPS is just too sensitive & the quality of the electric being produced by the Generator is just "too dirty" & tripping the surge protection circuit in the UPS,

You could try getting a std household multi adapter with a surge protection filter and see if that trips using a drill or lawnmower while plugged into the generator....

Try plugging the ups into your home power supply, then something into the ups, see if it works then. I charged my ups at home before plugging it into the generator.

You most possibly have the wrong type of UPS ! There are TWO types of UPS

Have a look here....

cant open the link Stu
it is a trust 1300kva
I rushed out and bought a kipor as i had a major show on saturday and ups was happy with that until we turned it off to refuel and the ups didn't last 10 seconds and took down viewing stations
i need ot do a bit more reading but if you think this is the wrong type of UPS then please let me know
thanks

This is what we have used before in the office RRP 400 on ebay below 100

http://www.apcc.com/resource/include/te ... u=sua1500i (http://www.apcc.com/resource/include/techspec_index.cfm?base_sku=sua1500i)

works with Honda EU20i (but it dosnt need) but not tested with non pure sinewave generator

worth dropping APC a line...
