ac or dc

[tommyrob123]

i have searched the web and cannot get a straight answer to this question. is the out put from the hornby p9100w ac or dc please. if it is ac then i can use it to power my turbines

This is a 15v 1a power adapter that is ideal for charging many jump starters that have a dc input and will replace the original one supplied.
This is a power adapter which delivers continuous fixed 15v dc power output, it can be used to safely and reliably charge the battery in your jump starter.
We recommend using a 14/15v adapter to charger the 12v battery
Charging should be higher than the battery voltage so as to prevent the battery wanting to discharge back into the adapter,.e,g, car 12V batteries charge at 13.8V. so ideally to charge your battery you need a DC 14V / 15V 1a adapter.
Leaving the charger on any longer than 10 hours can damage the battery, so we recommend a 9-10 hour charge time but always keep a check that the battery doesn't overheat.
The original adapter that was supplied with your jump starter maybe 12v but its likely to be the old style heavy unregulated chargers, that usually deliver alot higher than 12v to the battery.

eh!!!

Hi
I've no idea what the post by twalton1145 is about? As the Hornby P9100w is a power supply to feed a train controller and nothing to do with charging batteries or jump starters!

Simply look at the label.. It will specify the output voltage and whether DC or AC. Secondary DC output is defined by a short straight line over a dotted line. AC by a sine wave. Or it will simply say something like Output or Secondary (Sec) 16volt AC or DC etc
The image below shows the P9000W (Not quite the same but used for reference) and I've circled the output which on this one is 19 volts DC (Straight line over dotted line) at 500 milliamp (1/2Amp).


The one below is an AC output. Note the sine wave (wavy line).

thanks got it now. out put is dc.

There are loads of cheap 16V AC power supplies on eBay. I have couple of old laptop power supplies I use for auxiliary stuff like this.

Be a bit cautious where Laptop PSU are concerned, as quite often they are a DC output used for the laptops battery charging. Though some can be found with AC outputs. The DC ones are ideal for powering lighting etc on the layout and some are a higher DC output voltage of around 19 to 22 volts which are great for CDU charging on solenoid points.
Caution also needs to be used where the title says something like 'AC adaptor' as often the reference to "AC" is in fact the input mains supply!

That link is not a Hornby P9001W PSU. It is some look alike PSU! Plus its providing a 15v DC output. The OP needs a PSU with an AC output. As per his post here... viewtopic.php?f=9&t=3726

OOPS!! I'll keep my nose out in future
