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: 58.5-60.5 V DC
If an overvoltage occurs inside a
rectifier, the rectifier locks out.
If the external voltage is higher than
63 V DC for more than 500 ms, the
rectifier locks out.
AC surge
protection
Level-B surge protection, nominal lightning strike discharge current:
30 kA (8/20 µs). The maximum lightning strike discharge current is
±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 (at 25°C)
