Answer

Not certain why you are asking the question on this transformer instead of the controller unit you seem to be asking about. There is an indoor and outdoor version of the SST controller. The indoor uses this transformer. The outdoor version has a 24 VAC transformer built in to it and must be hard wired to your 120 volt AC. You should use an electrician for that. However if your controller will be under a porch roof outside, then the indoor model might work for 10 or even the 20 years that my older inside controller did. Then you will have something with an external power supply that won't require an electrician.

Unfortunately this transformer is built for the Rain Bird SST controller line. The SST 6 zone indoor would be an option to replace the ESP-6si

Not positive, if your current transformer only has two wires, a red and black wire, it should. May need to cut off the pre installed plug and splice back on your current plug if the connectors dont match

As long as your current transformer is around 24vac and 650ma or less and only has 2 wires it should. You may need to cut off the pre installed plug and splice on your old plug if the connections to the control pannel are different

Answer

Do not know. My old one was rated at 26.5V and 650mA. the new one worked rated at 25.5V and 650mA. So close. Yours is much more off, especially on the amperage.

The wiring inside the over 20 year old valve box was suffering from corrosion and rotting insulation that let wires make contact that shouldn't and burned out the original 20+ year old power supply. Likewise I burned out the first replacement as I didn't check and find that issue. The second replacement is working well. My only thing is that I had to cut the little connector off the end of the power cable as my 20+ year old controller doesn't have this connecter. It would have been nice if they came with the other matching connector so I could wire that in to my controller and easily change it in 20 or so years!
