Delta Elektronika SM3300 Series

Description

Programmable flexible DC power supply

The SM3300 Series consists of power supplies with excellent efficiency, stability and flexibility. Thanks to the auto-ranging power output, one power supply can cover two ranges of traditional power supplies with an rectangular VI-curve. For even more flexibility, the SM3300 series can be used at both single-phase as three-phase grid power.

Standard, the SM3300 series can be controlled via the front, web interface or Ethernet. This connectivity can be expanded at any time by our interface cards. Furthermore, the Master/slave interface allows parallel operation of up to 8 units.

cTUVus Certified

The SM3300 series is certified according to the UL 60950-1:2007 R12.11 standard. This certification by the reputable TÜV Rheinland is a confirmation of the high safety and quality standard of Delta Elektronika. This certificate combined with Delta Elektronika’s reputation of long term product availability and product support turns the SM3300 series into excellent power supplies for larger systems.

Auto-ranging output

Auto-ranging output in the SM3300 series allows the power supply to switch between two output regions dynamically. This feature boosts the power supply’s versatility, essentially performing the function of two traditional units. See the table below listing all variants in the SM3300 series to view all possible output regions. The L-curve VI-diagram demonstrates the auto-ranging behaviour.

High speed programming and Power sink

The SM3300 series offers optional 10-20x higher programming speed and lower output capacitance, perfect for laser applications, fast test systems, or as a low parallel capacitance current source in plasma chambers. The Power Sink Option absorbs bursts of power, maintaining constant output voltage. It’s ideal for PWM-speed control in electric motors and automotive waveform generation.

Excellence and high value

The SM3300 series showcases outstanding load response behaviour, upholding Delta’s legacy of minimal electromagnetic interference, reduced audible noise, and high reliability and efficiency. Equipped with flexible output, a standard web interface, and plug-and-play interfaces, it proves indispensable across a multitude of applications. See the data-sheet for more information.
