The 9120A series are laboratory grade, programmable DC Power Suppies providing great performance and features not found in other supplies in this price category. The power supplies were designed to meet the needs of today applications in R&D design verification, production testing or university labs that require clean and reliable power, high resolution/accuracy and fast transient response time.

  • Excellent display resolution
  • Fast transient response time (< 150 µs)
  • SCPI compatible
  • Communicate via RS232 or USB Interface, using included RS232 to TTL or USB to TTL serial converter cable
  • GPIB interface (model 9123A only)
  • Closed case calibration
  • Compact size for bench use or rack mountable (2U x 1/2U size)
  • DVM and Milliohm Meter
  • Discrete Fault Indicator/Remote Inhibit (DFI/RI). Useful for turning multiple power supplies On/Off simultaneously
  • Application Software for front panel emulation and simple test sequence generation included
  • Sheathed banana plug terminals for safety
