0 to 30 Volts DC Output at 0-2 Amps Adjustable Current Limiting Constant Voltage/Constant Current w/Automatic Crossover Excellent Load and Line Regulation Low Ripple & Noise Floating Output--Can be used in Positive or Negative Ground Circuits Reverse Voltage Protection Built-in Short-Circuit and Overload Protection Options--10-Turn Voltage and Current Controls At last, a lab-grade, high capacity power supply at a truly low price. This bench-type supply is ideal for circuit development and a wide variety of industrial and servicing applications. Its versatility and ease of operation makes it perfect for student lab use. The Model 3002A is one of the greatest power supply values you'll ever find! Special features include fail-safe short-circuit protection, low output drift and precision CV/CC operation. In addition to protecting integrated circuits and other sensitive load devices, this supply can be used as a current regulated power source. The 3002A is loaded with other features too: separate panel meters to accurately monitor the output voltage and current series or parallel capability heavy-guage metal cabinet fused three-wire power cord convenient binding post terminals. Long-term reliability is assured by a conservatively designed regulator circuit and the use of high quality components. SPECIFICATIONS: Output Voltage: 0 to 30 volts DC, two-ranges (0-15V, 15-30V), continuously variable between ranges. Output Current: 0 to 2 amperes. Voltage Regulation - Load/Line: 0.05% from zero to full load/0.02% from 105 to 125VAC. Current Regulation - Load/Line: 0.25% from short-circuit to 30V/0.1% from 105 to 125VAC.
