Verifying PP-4763A 230-volt input
The above voltage regulation test was conducted at 115 volts. If a 230-volt, single-phase, 50/60
H z power source is available, test PP-4763A at 230-volt input.
Procedure:
S e t TB-1 ac input links to 230 volts ac.
Connect power cable to 230-volt source.
Repeat test equipment settings, control settings for step 1 of paragraph 2-14 in test chart.
Repeat ripple voltage, dc output voltage checks in step 1 of paragraph 2-14.
