DESCRIPTION:

The Delta Elektronika SM 100-AR-75 is a 3300W programmable DC power supply designed for laboratory, industrial, OEM, and automated test applications requiring precise voltage regulation and high output flexibility. The unit forms part of the Delta Elektronika SM3300 series and incorporates autoranging output technology for extended voltage and current operating capability from a compact 2U chassis platform.

The SM 100-AR-75 provides dual operating ranges of 0-50V at 0-75A and 0-100V at 0-37.5A, allowing the power supply to support a wide range of electronic development, telecommunications, industrial automation, battery simulation, aerospace, and production test applications from a single platform. The high-efficiency switch mode design delivers up to 90% efficiency together with low ripple and low noise output characteristics suitable for precision DC supply applications.

The power supply supports programmable voltage and current control with integrated Ethernet interface capability for remote operation and automated instrumentation system integration. The unit supports universal 180-528V AC input operation at 48-62Hz and incorporates temperature-controlled forced-air cooling together with overload, short-circuit, overvoltage, and thermal protection systems for continuous-duty industrial operation.
