The Sorensen DCS300-3.5 is a programmable DC power supply delivering 1000W continuous output across 0–300 VDC and 0–3.5 A. Engineered for precision control in test automation, R&D, and industrial applications, this unit combines high power density with low-profile packaging and operates in constant voltage or constant current modes. Switching rates up to 100 kHz enable fast transient recovery—typically 500 μs to 1% settling—while output ripple of 20 mV RMS and noise of 200 mV peak-to-peak ensure clean, stable power for sensitive loads.
