High-Precision Programmable Linear DC Power Supply

The SIGLENT SPD3303 series is the latest high-precision programmable linear DC power supply from SIGLENT Technologies. The new SPD3303 series design is based on previous SIGLENT designs. This product not only combines the outstanding features of its predecessors’ products, but also brings in many new features. These features include front panel programmable, timing output, graphical interface display?smart temperature-controlled fan and PC remote control communication.

The SPD3303 series DC Power Supply has separate output channel control and independent triple outputs, independent, series and parallel output modes. It also includes many advanced features, including comprehensive over voltage/current/temperature protection, 100V/120V/220V/230V compatible design, low ripple and noise, fast transient response, USB interface, which provides the SCPI remote control command set and LabView driver.

Triple Output with 2 Floating Outputs

Provides individual +, - operation or tie them to ground for +/- sourcing (+/- 12V input for OpAmp control, for example)

Auto-Series/AutoParallel Connections

Quickly connect CH1 and CH2 in either series or parallel to double voltage/current output (SPD3303X, X-E

User selectable CC/CV protection limits

Customize your voltage and current limits to protect your circuit/devices
