Variable Voltage Supplies
The Elenco variable voltage supplies all feature failsafe automatic overload protection with output current externally adjustable. Special circuit protects equipment, user and itself. Current limiting adjustment is easy. Simlpy short output and adjust limit control to read desired maximum current. The output voltage is continuously variable and precisely held to your setting. Ideal for use in labs, service shops, schools, home and industry.

Dual 020V @ 1A 5V @ 5A 
Model: XP660

Model: XP760

The XP660 and XP760 contain three fully regulated power supplies. Two are 020V @ 1A and a fixed 5V @ 5A. All three are isolated from each other so that they can be stacked to produce up to 45V @ 1A. All supplies are protected against short circuit. The 020V supply incorporates externally controlled current cutoff circuits with an LED indicating current overload. The Model XP660 has two analog meters which can read voltage or current. The Model XP760 has two high accuracy 3digit LED Volt/Current meters. Made in U.S.A.
