Keysight (Agilent) N5768A

The Keysight N5768A is a 1520 W single-output DC power supply engineered for automated test equipment (ATE) systems in research, design validation, and manufacturing environments. Housed in a compact 1U rackmount package, it delivers 0–80 VDC at 0–19 ADC with exceptionally low output ripple and noise at 8 mVrms. The unit combines precise voltage and current control with multiple protection mechanisms—over-voltage, over-current, over-temperature, and under-voltage lockout—ensuring safe operation under demanding conditions. Active Power Factor Correction (PFC) at 0.99 typical minimizes input harmonics across universal 85–265 VAC supplies.
