The 6289A Power Supply is a constant voltage/constant current power supply featuring separate coarse and fine voltage and current controls which allow the voltage and current to be varied form 0 to 40 VDC and 0 to 1.5 A, it has a load effect of 0.01% +2 mV in voltage and 0.01% +250 ?A in current. This power supply has a four position meter function switch to select either of two output voltage or output current ranges for display on the panel meter. Other features include remote sensing and programming, auto series, auto-parallel and tracking operation, front and rear output terminals, and floating output. Input requirements are 115 VAC (?10%), 48 to 440 Hz. The 6289A is a reliable medium range power supply capable of many applications in the lab or production line.
