Astron VS Series Linear Power Supplies
These Astron Corporation VS Series Linear Power Supplies offer continuous output current ratings from 9 to 57 amps at 13.8 V, depending on the model. Adjustable current limiting is from 1.5A to the maximum rated output! Front panel controls provide current limiting and voltage adjustment, while dual meters monitor the output condition. Manufactured as traditional power supplies, they utilize robust components for durability and long life!
Designed to be exceptional bench supplies, these supplies offer flexibility of output voltage, coupled with current limiting, making them superb test equipment! All Astron Corporation VS Series Linear Power Supplies provide a highly regulated variable DC output for the operation of mobile or portable equipment from 110-120 volt wall current (some models are available to operate on 220-240 Vac). VS Series power supplies with a cigarette lighter socket on their front panel also have DC output terminals on the rear panel. Some models now have Anderson Powerpoles and rear panel DC output terminals, as well. That's convenient!
