DESCRIPTION:

The Delta Elektronika SM660-AR-11 is a 3300W programmable autoranging DC power supply designed for precision laboratory, industrial, and automated test applications requiring stable high-voltage DC output capability. The unit provides dual autoranging output ranges of 0-330V at 0-11A and 0-660V at 0-5.5A, allowing flexible voltage and current combinations within the rated power envelope for improved utilisation across varying load conditions.

The SM660-AR-11 utilises high efficiency switch mode power conversion technology with efficiencies up to 92%, active power factor correction up to 0.99, low ripple and spike characteristics from 3mV RMS / 12mV peak-to-peak, and recovery times from 100µs under dynamic load conditions. The unit is suitable for aerospace systems, insulation testing, telecommunications infrastructure, endurance testing, industrial automation, photonics applications, and automated production environments requiring precision regulated high-voltage DC output.

Designed within the Delta Elektronika SM3300 series platform, the power supply supports Ethernet control as standard together with voltage/current monitoring, remote sensing, programmable sequencing, and automated instrumentation system integration capability. Optional interface configurations include RS232, IEEE488, CANBUS, PROFIBUS, isolated analogue programming, high-speed programming, and power sink functionality depending on application requirements.

The compact modular design supports both single-phase and three-phase 180-528V AC input operation with temperature-controlled low-noise forced-air cooling and comprehensive overload, short-circuit, overvoltage, and thermal protection systems. The SM3300 platform is designed for continuous-duty industrial operation with MTBF specified at 500,000 hours and EMC performance exceeding CE requirements for low emission and high immunity environments.
