The maximum output power is the number
of rectifiers multiplied by the output power
of a single rectifier.
≤ ±1%
≤ 200 mVp-p
≤ 2 mV
< ± 5% (20%-100% load percentage)
> 300 V AC
When the voltage is restored to 290 V AC,
the output resumes.
< 85 V AC
When the voltage is restored to 90 V AC,
the output resumes.
Range: -58.5 V DC to -60.5 V DC
1. If an overvoltage occurs inside a
rectifier, the rectifier locks out.
2. If the external voltage is above –63 V
for more than 500 ms, the rectifier locks
out.
