Dual Range Laboratory Bench Power Supply

Here is A cost-effective, lab-grade bench power supply from Electro Industries, the Model 3670. Its dual range capability of this bench power supply provides reliable and continuous operation over very popular volt/amp combinations. The versatile 3670 can replace several competitive single range power supplies which could result in considerable savings both in bench space and cost. The full 7 amp capacity of the 18V range is well suited for many high current applications encountered in school labs, industry and automotive servicing. The 36V/3.5A range is ideal for design labs, incoming inspection of components/subassemblies, production testing and a wide variety of educational uses.

Features of the 3670 Bench Power Supply:

• 0-18VDC/0-7A or 0-36VDC/0-3.5A
• Constant Voltage/Constant Current (CV/CC) Modes with Automatic Crossover
• Adjustable Current Limiting
• Coarse and Fine Voltage Controls
• Series or Parallel Operation
• Floating Output Permits Use as a Positive or Negative Source
• Built-in Short-Circuit and Reverse Voltage Protection
• Optional 10-turn Current Potentiometer
