Delta Elektronika SM7020D

The Delta Elektronika SM7020D is a 700W autoranging DC power supply engineered for laboratory testing, R&D, and precision electronic applications. Dual-output ranges deliver 0–35V at up to 20A or 35–70V at up to 10A, with automatic range switching to maintain full 700W capability across both voltage bands. Low-noise output, fast transient response (100µs recovery at 25°C), and comprehensive protection systems ensure reliable operation in demanding test environments. Master/slave parallel and series operation enable expanded power configurations for multi-unit setups.
