Looking at 12volt power supply for my Honda EU10i generator

http://www.grahams.com.au/Grahams/index.cfm?ID=184&ProductView=421

It only puts out 8 amps (non regulated)

What if I plugged in a Powertech Switchmode 3-15volts - 40 A Unit.

http://www.rpc.com.au/products/batteries/switchmode/switchmode.html

Would the switchmode power supply function normally ( should do as the
Honda output is sine wave "and will run sensitive equipment:?)

Will the Honda generator have enough power (1000 watts) for the
switchmode supply (40x15 + 10%) (assume 90% efficiency) = 700watts.

I have heard that at least with the industrial 240 volt generators -
switchmode power supplies may not work and that with transformer type
power supplies the power rating of the generator needs to be much more
than the power rating of the transformer type power supply. Does this
apply to switch mode power supplies and generators such as the Honda
10EU1?

** The SMPS will draw about 6 amps *rms* from the supply at full load -
this is because of the very spiky current of the non PFC waveform. Contact
Powertech for confirmation of the exact figure.

The Honda is rated at 900 watts continuous or 4 amps rms at 230 volts AC.

Bet it will self protect and turn off after a few minutes.

Why not use the 240v for the PSU ??

The Honda generator will probably not start up your power supply. On my
Honda 10EU1 the maximum smart battery charger it would run was 30A at
12V,(which actually only gave out about 28A max). Anything bigger an the
10EU1 would rev up to try to start it, but after about 5 seconds would
shut down to protect it self.

Heh heh, I use my venerable Honda E300 with a jumped up computer PSU without
any problems, just a modest 12.5amp output but the genny handles it no
worries.

Thanks for that info Phil,

No doubt the numbers advertised are to impress, but in real life it
sounds as though my expectations are not to be met. Looks like these
SMPS are sold under the name Powertech and Manson
http://www1.tpgi.com.au/users/p8king/sps8041.htm

I will see if I can get some more technical info.

Looks like the SMPS is made by Manson out of Hong Kong.

Here is the PDF specs sheet

http://www.manson.com.hk/downloads/product_infosheet/SPS8494V2001r1.pdf

Not that helpful PFC >0.95 at optimal load, efficiency > 78%

No mention of input "rms" amps. ?Chances of them answering an email?

Nothing like real life experience. Do you have the name of the battery
charger you tried?

What rating are gensets that cheap? I'd be expecting some pretty short life
and a bit of huntin'.

You get what you pay for, not much. A petrol 2-stroke motor, with a
700w generator attached. Considering its only designed to run a couple
of lightbulbs and maybe a TV or radio during a blackout i'm not too
concerned about its lifespan. It would be lucky to get 20hours use
over the storm season each year.
