The Power Ten 3300D is a rack-mounted DC power supply delivering up to 1000 W of stable, regulated power for laboratory test and systems applications. It operates in constant current/constant voltage (CC/CV) mode with automatic crossover, providing precise output control across multiple voltage and current configurations. The unit features exceptional line and load regulation of ±0.05% per 8 hours, combined with low ripple (30 mV maximum) and fast recovery within 2% of original value in 10 ms during 30% step load transients. Remote sensing capability compensates for line drop up to 3% of rated voltage per line, ensuring accurate voltage delivery at the point of load. Analog control inputs on the rear panel enable external voltage and current programming, while on/off control accepts contact closure, 6–120 VDC, or 12–240 VAC signals. The 1RU form factor (19.00″ W × 18.50″ D × 1.75″ H) integrates into standard 19-inch rack systems with a maximum weight of 15 lb. Designed for commercial environments, the supply complies with FCC Class A digital device limits and requires proper grounding due to high chassis leakage current.
