Part # PX300
12V 300 watt Galvanized Steel Transformer
Safety transformer supplies 12 volts to pool and spa lights, submersible fixtures and outdoor garden lights.
Designed for safe operation with a grounded shield between the primary and secondary windings. Also includes built-in circuit protection that disconnects power to the transformer in case of defect or overload.
Can be used with multiple 12v lights, not to exceed total wattage of 300.
Can the PX300 transformer be used to power the Hayward SP058150 AstroLite Pool Light (the light is 300 watt, 12 volt)
Hi. Yes, this PX300 transformer can be used to power the Hayward SP058150 light.
My LED pool light flashes only briefly when the switch is thrown; it won't flash at all after that when switched on (unless I wait awhile). Is the problem likely the transformer? I have an INtermatic PX100. thanks!
Hi Chris, Yes, the problem could be the transformer not sending the correct voltage to the light.
will this transformer work with 2 penstar lights using 69100000 bulbs
You would need two transformers as each light is 200 watts.
I have 300 W - 120 V 60Hz weather proof unit that has the ratings of 15V Max.OCV with a secondary current rating @ 25 amps. Is your unit compatable as a replacement? even though it rates a 3 amps
Hi Gary, The PX300 is not compatible because it's maxed amperage is 3..
put new transformer on got a 300 cause could not read what wattage was on old one does it matter???> I did see after the fact it was a 100 watt transformer
Hi Sal, The 300 Watt Transformer will work if you have a 100 watt light as long as the total wattage does not exceed 300 watts.
would this work with a Hayward AquaRite (Goldline) electronic chlorine generator ? if so, which size wattage is suitable for an 18 x 36 in ground pool?
Hi Roland, this transformer will not work the Hayward Goldline Aquarite. You would need this Hayward Aquarite Transformer.
Is this unit acceptable for replacing the SafetyVolt ST300 pool lght transformer?
Hi SLR, This Intermatic 300 Watt Transformer will replace your SafetyVolt ST300 transformer.
2 of my pool lights went out weeks apart. The pool service states that I must have a 300 watt light replacement vs a 100 watt light replacement because I have a 300 Watt Transformer. Is this true?
Hi, Yes, a 300 watt transformer is typically used with a 300 watt 12 volt pool light.
How can I hookup a timer to use the PX300 with garden lighting? Thanks
Hugh, The PX300 would be installed just like any 12v transformer. The unit comes with instructions.
Is this transformer hardwired to 120V or plugs into outlet? Does it have a switch to turn on and off pool lights?
Hi Costas, The transformer is hard wired to the breaker box that controls the pool lights.
My new international 300 watt transformer buzzes continually when turned on. Installed by a pool company. They don't know how to fix it. How can I fix it? Thank you.
Hi James, I'm not sure what's causing the buzzing sound, I would recommend contacting Intermatic at 815-675-7000 to troubleshoot.
The operation and service manual states that the input must be 120v 3 amp max. How do I insure that I do not exceed 3 amps input?
Hi Mike, If you are using this for a pool or spa light then as long as you stay at or below 300 Watt lighting then the amperage would be below 3 amps. This can be the combination wattage of multiple lights, for example three 100 watt lights would be fine. A standard 300 watt pool light draws 2.5 Amps at 120V.
is the voltage on the 12v side ac or dc?
Tom - The voltage on the 12V side is still AC.
DO THESE GO BAD MY POOL LIGHT COMES ON BUT VERY WEAK AND DOESN'T MIX THE COLORS LIKE WHEN IT WAS NEW
Sam, The Intermatic 300 Watt Transformer can go bad, however you may want to an electrician take at look at your lighting system because the light being dimmed may not be due to the transformer.
I have a PX300 trying to run a pool light by Haywood, 12V 300 watt. The pool light would come on sometimes, then shut down. I had a spare PX300 new. Installed it. Have 12.18 volts to the light. Nothing lights. I tried 2 new bulbs. Nothing. Went straight to the transformer, hooked up a drop light with wire nuts to 12 volt leg and ground. Nothing. Ideas? Am I missing something?
Terry, Sorry to hear of your issue. I would recommend calling Intermatic to trouble shoot. You can reach them at 815-675-2321.
Does it matter which lead is connected to the pool light wire after the transformer, they are identical, both are black.
Hi Allan, It doesn't matter, just make sure they are the 2 thicker black wires that are going to the 12 volt light.
Can this transformer be connected to a 230v source?
Hello Julio - Unfortunately this transformer cannot be hooked up to 230v.
If a use a 300 watt transformer but only have 75 watts of LED lights does the transformer consume the 300 watts or the 75 watts being used by the LED lights?
It would only consume the wattage needed. No more.
How much does this weight?
This transformer is twelve(12) pounds(lbs).
Can you hook up more than one light to this transformer?
The PX300 is a 300 watt transformer. You can connect multiple lights to the transformer as long as the total combined wattage does not exceed 300 watts.
I am going to purchase two 12 Volt lights do I need to purchase a transformer with these lights?
The power coming from your house is 120V so you will need to purchase a transformer to drop the voltage from 120V coming from your house down to 12V going to the pool light. We sell two transformers the PX100 which can handle up to 100 watts and the PX300 which can handle up to 300 Watts. You may also put multiple lights on one transformer, for example if you had two 50 watt lights then you would only need to purchase one PX100 transformer and wire both lights into this single transformer.
Is is this transformer weather proof?
Yes the Intermatic transformer is weather proof.

Pros: Does what it's supposed to.
Cons: Kind of noisy, mount it away from where you will be.
Had it for nine months with an Intellibrite systems, works OK. It does make noises when the lights are programming (the controller programs the lights by powering off and on rapidly a set number of times for each color or program), and hums a bit otherwise. I have it mounted on a back wall behind a screening fence, still can hear it.
