DESCRIPTION:

The Delta Elektronika SM 400-AR-4 is an 800W programmable autoranging DC power supply designed for precision laboratory, industrial, and automated test applications requiring stable high-voltage DC output performance. The unit provides dual autoranging output capability of 0-200V at 0-4A and 0-400V at 0-2A, allowing flexible voltage and current combinations within the rated power envelope.

The SM 400-AR-4 utilises high efficiency switch mode power conversion technology with precision voltage and current regulation, low ripple and noise characteristics, and excellent dynamic response performance suitable for electronics development, aerospace systems, telecommunications infrastructure, endurance testing, industrial automation, and component validation environments.

Designed within the Delta Elektronika SM800 series platform, the power supply supports analogue programming, voltage and current monitoring, remote sensing, and automated instrumentation system integration capabilities. The unit also supports series and parallel operation configurations for expanded system flexibility.

The compact high-density design incorporates temperature-controlled forced-air cooling together with overload, short-circuit, overvoltage, and thermal protection systems for continuous-duty industrial operation. Optional high-speed programming, Ethernet, RS232, isolated remote programming, and power sink functionality are available depending on configuration requirements.
