MX Series 307
OVER VOLTAGE
This test will change the output voltage for the selected phase in the following
sequence:
28V system:
• 50V for 50msec.
• The voltage gradually decays with time to 31.5 volts by the
following equation:
= 31.38 +
0.93
Where: 0.05 ≤ ≤ 7.758
• Stay at 31.5V for 92.242 seconds before returning to 28V.
270V system:
• 350V for 50msec.
• The voltage gradually decays with time to 290 volts by the
following equation:
= 298.6 +
3.02
Where: 0.05 ≤ ≤ 7.55
• Stay at 290V for 92.45 seconds before returning to 270V.
Prior to the test, a range change may take place if the power source is set at
the low voltage range. NOTE: See Section 9.6.1.7.2 under HIGH VOLTAGE.
The ← key (backspace) will terminate the test at any time.
NOTE: A range change will result in momentary loss of power to the EUT.
If this is not acceptable, the power source must be always left
in high range.
UNDER VOLTAGE
This test will change the output voltage for the selected phase in the following
sequence:
28V system:
• 0V for 7sec.
• 20V for 93sec.
270V system:
• 0V for 7sec.
• 240V for 93sec.
The ← key (backspace) will terminate the test at any time.
