A Technical Specifications
≤ 5% (load percentage ≥ 50%)
–42 V DC to –58 V DC
–53.5 V DC
Maximum output power = Output power of
a single rectifier x Number of rectifiers
≤ ±1%
≤ 200 mVp-p
≤ 2 mV
< ± 5% (20%–100% load)
> 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.
–58.5 V DC to –60.5 V DC
1. If overvoltage occurs due to an internal
fault, the rectifier locks out.
2. If the external voltage is greater than
–63 V for more than 500 ms, the
rectifier locks out.
