Adjustable D.C. Current Source
Product Code : JA-SI-8050
The Adjustable D.C. Current Source (SKU JA-SI-8050) is a mains-operated supply that delivers a continuously adjustable direct current of up to 10 A for college physics and electrical laboratories. A variac feeds a step-down transformer, bridge rectifier and filter circuit, the output of roughly 0-10 V DC is set to give the current the external load needs, and a built-in 0-10 A ammeter shows the current on the front panel.
