≥ 0.99 (load ≥ 50%)
≤ 5% (load ≥ 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
the output resumes.
-58.5 V DC to -60.5 V DC
 If overvoltage occurs due to an internal
fault, the rectifier locks out.
 If the external voltage is greater than
-63 V for more than 500 ms, the
rectifier locks out.
