The Astron VS-50M is a high quality, linear, regulated power supply providing variable voltage from 2 to 15 VDC at up to 50 Amps continuous or 37 Amps ICS. The front panel features an illuminated on/off power switch. There is a separate meter for voltage and one current. The knob on the left is used to limit the output current from 1.5 to 50 Amps. The knob on the right controls voltage from 3 to 15 VDC. There are large heat sinks on the left right panels. The rear panel has two terminal posts and easy fuse access.

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 your 115-volt wall current. VS Series power supplies with only cigarette lighter sockets on their front panel still have DC output terminals on the rear panel.
