The Sorensen PRO32-310T is a programmable DC power supply engineered for demanding benchtop and automated test equipment (ATE) applications requiring precise voltage and current control. Delivering 10 kW across a 0–32 VDC, 0–310 ADC output range, this unit combines excellent regulation with low noise performance and flexible programming interfaces.
Technical Specifications
Output voltage spans 0–32 VDC at up to 310 ADC, yielding approximately 10 kW at full rating. Line and load regulation holds better than 0.1%, with line regulation at 0.01% + 2 mV and load regulation at 3 mV. RMS ripple measures as low as 20 mV; peak-to-peak noise reaches 120 mV. Normal mode voltage ripple is specified at 500 µVrms / 5 mVpp. Efficiency stands at 80% at full power.
Voltage programming resolution achieves 0.03% of full scale (1 mV granularity), while current programming resolution reaches 0.03% of full scale (100 µA granularity). Programming accuracy is ±(0.1% + 0.1% of maximum output voltage) for voltage and ±(0.1% + 0.4% of maximum output current) for current. Readback accuracy is ±(0.1% + 0.15% of full scale output voltage) and ±(0.1% + 0.4% of full scale output current).
Transient response time is typically 40 ms for 50% load changes (25% to 75%). The unit employs SCR preregulator topology and supports both constant voltage and constant current operation with foldback mode protection.
