The Power Ten P66C-60330 is a 20 kW DC power supply delivering 0–60 VDC at up to 330 A, engineered for industrial and commercial systems requiring precise voltage and current regulation. This three-phase unit operates from 190–253 VAC (47–63 Hz) and combines PWM topology with zero crossing efficiency for stable, low-ripple output. Regulation performance meets 0.1% line and load regulation, 0.5% current regulation, and ±0.05% per 8-hour stability. Front-panel controls govern voltage, current, and over-voltage protection; rear-panel interfaces enable remote on/off, output monitoring, and analog voltage/resistance programming. Built-in protection includes OVP, current-limit fold-back, over-temperature shutdown, brown-out protection, and soft-start limiting. Output ripple remains 75 mV peak-to-peak typical. Transient response recovers to ±2% of set voltage within 10 msec following a 30% current step. Temperature coefficients of 0.02%/°C (voltage) and 0.03%/°C (current) ensure performance consistency across thermal variation.
