Sorensen QRB40-.75, variable power supply, hi quality
Hello. I am selling one used power supply made by Sorensen in the USA. This is a lab type supply that puts out between zero and 40 volts D.C. and up to 800 ma. The output is continuously variable and has eight preset current limits via front panel switch. I believe the intent is to protect the equipment from an overload or short on it's load. As you can see in the pictures it has metering which looks at either the output voltage or current. I have tested this item and it does work. The only thing I can find wrong is the front panel power lamp does no light. This is a neon type bulb and I have not bothered to replace it. Other than that it is in remarkably nice condition. This is not some cheap import but made back when the U.S. actually made stuff. Looking inside the components appear to be very heavy duty and of excellent quality. I will guarantee it to work when you get it. The weight is around 11 lb. unboxed. Thanks for looking!
