Programmable DC Power Supplies 9120A Series Technical data subject to change © B&K Precision Corp. 2017 www.bkprecision.com Model 9120A 9121A 9122A 9123A 9124 Output Voltage 0 - 32 V 0 - 20 V 0 - 60 V 0 - 30 V 0 - 72 V Output Current 0 - 3 A 0 - 5 A 0 - 2.5 A 0 - 5 A 0 - 1.2 A The 9120A series are laboratory grade, programmable DC Power Supplies 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’s 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. Features and Benefits n Excellent display resolution n Fast transient response time (< 150 µs) n SCPI compatible n Communicate via USB Interface, using included USB to TTL serial converter cable n GPIB interface (model 9123A only) n Closed case calibration n Compact size for bench use or rack mountable (2U x 1/2U size) n DVM and Milliohm Meter n Discrete Fault Indicator/Remote Inhibit (DFI/RI). Useful for turning multiple power supplies On/Off simultaneously n Application Software for front panel emulation and simple test sequence generation included n Sheathed banana plug terminals for safety Front Panel Operation The numeric keys and rotary knob provide a convenient interface for setting output levels quickly and precisely. Voltage and current can be set to a maximum resolution of 0.5 mV (2 mV for 9124) and 0.1 mA respectively. Up to 50 parameters can be stored and recalled from internal memory. Extra Features The 9120 series’ digital port offers a variety of configurations. The port can operate in digital I/O, external trigger and DFI/RI (Discrete Fault Indicator/Remote Inhibit) mode. The RI feature can be used for turning several power supplies On/Off simultaneously. External triggering can be used in combination with List mode. The included application software supports front panel emulation and allows users to generate simple test sequences without the need to write source code. Additionally, the power supply comes with a built-in 5 1/2 digit DVM and high resolution milliohm meter supporting 4 wire measurements. Remote Interface The power supplies can be remotely controlled from any PC through a USB (virtual com) interface, allowing the user to program and monitor all parameters through easy to use SCPI commands. The power supplies come with a USB to TTL serial converter. Additionally, model 9123A can be controlled via GPIB interface and includes a GPIB to TTL conversion adapter cable.
