Dual Output Laboratory Bench Power Supply 0~30V/3A

Features of the 303D Bench Power Supply:

• Two Fully regulated 0-30 volt/3A DC outputs
• Tracking or independent operation
• Continuously adjustable current limiting
• Four-meter display assures accurate monitoring of both voltage and current outputs
• Mode lights indicate CV or CC operation - automatic crossover
• Coarse/fine voltage controls and current limit controls
• Short-circuit, reverse polarity and overload protection
• A fully dissipative series pass circuit provides excellent regulation and very low ripple noise
• Positive or negative ground operation or supplies may be "floated"
• Series or parallel operation for increased output capabilities
