I have a B&K Precision Digital display 0-30 vdc power supply for sale, model # 1635. I purchased the supply sold for $ 329.00 will sell for $ 100.00 plus shipping from area code 17331. Will also monitor external dc power as well.The 0 to 30 vdc output is variable.
Voltage output very accurate.170 watt total output.Very good testing and calibrating devices. Thanks: Ed
