Specifications
Power factor
≥ 0.99 (rated input and 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
The maximum output power is the number
of rectifiers multiplied by the output power
of a single rectifier.
Regulated voltage precision
≤ ±1%
Ripple and noise
≤ 200 mVp-p
Noise weighting
≤ 2 mV
Imbalance of load sharing
< ±5% (20%-100% load percentage)
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 V DC to -60.5 V DC
If an overvoltage occurs inside a
rectifier, the rectifier locks out.
If the external voltage is above –63 V
for more than 500 ms, the rectifier locks
out.
AC surge
protection
Level B surge protection; nominal surge discharge current: 30 kA (8/20 µs); maximum
surge discharge current: 60 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.
MTBF
200,000 hours
