Greetings, Would someone tell me about specs of this transformer. I belongs to power supply of Samsung SAMS4 Cash register.

I attached two pictures.
I guess ER-650 means that primary winding is 650 turns and ER-5200 means that secondary winding is 5200 turns.
It weighs 1100 (gr) or 2.4 (pounds).
It has two secondary winding, 20 volts (thick wire) and 25 (thin wire) volts.
Please correct me if I'm wrong.

I don't understand JK26-00012A.
What would be the maximum output current?
Does 000012A mean 12 AMPs?
Does JK26 mean something like a connector?

Thanks.

I don´t think any of the markings mean anything useful, transformers are almost allways custom jobs, and if anything it would state the voltage and current, not number of turns which is of no use to anyone.

Thank you everyone. You are right, those numbers and letters are parts numbers. I bought them really cheap and they have come to be very useful as amplifier power supply. I'm not what the max current this transformer can hit without much voltage drop and heat dissipation but they passed constant 2 Amps application test. Good enough.

I wanted to shared the findings based on Service Manual.

Blue-Blue wires: AC 19 volts 2.3 Amps
Red-Red wires: AC 24 volts 0.15 Amps
