Input voltage 85 V AC–300 V AC
Input frequency Range: 45-66 Hz; nominal frequency: 50/60 Hz
Power factor ≥ 0.99 (Rated input and full load)
Total harmonic distortion (THD) ≤ 5% (Vin = 208 V AC, 220 V AC, 230 V AC, 50%-100% load)
DC output Output voltage range -42 V DC to -58 V DC
Default output voltage –53.5 V DC
Output power Maximum output power = Output power of a single rectifier x Number of rectifiers
Regulated voltage precision ≤ ±1%
Ripple and noise ≤ 200 mVp-p
Noise weighting ≤ 2 mV
Imbalance of load sharing < ±5% (20%-100% loaded)
AC input protection AC input overvoltage protection threshold 300 V AC
AC input overvoltage recovery threshold When the voltage is restored to 290 V AC, the output resumes.
AC input undervoltage protection threshold < 85 V AC
AC input undervoltage recovery threshold When the voltage is restored to 90 V AC, the output resumes.
DC output protection DC output overvoltage protection threshold Range: 58.5-60.5 V DC

1. If an overvoltage occurs due to an internal fault in a rectifier, the rectifier locks out.

2. If the external voltage is higher than 63 V for more than 500 ms, the rectifier locks out.

AC surge protection Level-C surge protection, nominal lightning strike discharge current: 20 kA (8/20 µs). The maximum lightning strike discharge current is 40 kA (8/20 µs).
DC surge protection Differential mode: 10 kA (8/20 µs); common mode: 20 kA (8/20 µs)
Safety and regulatory design Complies with the IEC/EN60950-1.
Mean time between failures (MTBF) 200,000 hours (at 25°C)
