  • Yesterday's electronic equipment used to be easy to power, you simply plugged in a 12 volt "wallwart" and depending on the load, you had somewhere between 11 to 17 volts DC output. The output was not regulated and the output was totally dependent on the load of the circuit connected to it! On top of that, filtering wasn't the greatest and unless DC filtering was included in the device, hum was typical. We won't even begin to talk about short circuit protection, efficiency, or regulatory approvals!

    If you're looking for a great 12VDC power supply for "today's" equipment, look no further! Due to thousands of requests, we have had a 12VDC supply custom designed to meet your needs, while maintaining a price you can afford. In fact this little gem is priced identical to our time honored and highly popular AC125 unregulated 500mA supply! This little switcher produces clean regulated 12VDC at a whopping 1A of current. Line regulation is maintained to +/-1% to assure a constant operating voltage to your equipment or kit. Input voltage "simply doesn't matter!" Operating between 90 volts to 264 volts input, you can be assured the power supply will work anywhere you take it! If you're concerned about EMI and RF issues, you can put your mind at ease; we've added a ferrite core at EACH end of the cable! The output plug is a standard 2.1mm connector to match not only the bulk of Ramsey products, but the majority of 12VDC equipment inputs throughout the industry.
