≤ ±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

If overvoltage occurs due to an
internal fault, the rectifier locks
out.

If the external voltage is higher
than –63 V DC for more than
500 ms, the rectifier locks out.
