Variable Voltage Supplies

The Elenco variable voltage supplies all feature fail-safe 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 0-20V @ 1A     5V @ 5A

Model: XP-660

Model: XP-760

The XP-660 and XP-760 contain three fully regulated power supplies. Two are 0-20V @ 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 0-20V supply incorporates externally controlled current cutoff circuits with an LED indicating current overload. The Model XP-660 has two analog meters which can read voltage or current. The Model XP-760 has two high accuracy 3-digit LED Volt/Current meters. Made in U.S.A.

0-30V @ 5A

Model: XP-605

The XP-605 has an output of 30Vdc @ 5A. Its features include fine and coarse controls for voltage and current, and contains two analog Volt/Current meters.

The supply incorporates an externally controlled current cutoff circuit with an LED indicating current overload. Protected against short circuits and overloads.

0-50V @ 3A

Model: XP-752

The XP-752 has an output of 50Vdc @ 3A. Its features include fine and coarse controls for voltage and current, and contains two 3-digit LED Volt/Current meters

The supply incorporates an externally controlled current cutoff circuit with an LED indicating current overload. Protected against short circuits and overloads.
