2.4 Overshoot
Any overshoot at turn on or turn off shall be less 10% of the normal voltage value.
2.5 +5VSB ERP
2.5.1 +5VSB ERP
When the power supply is in the standby state,
AC 115V / 60Hz, + 5 Vsb load is 0.0A, and theinput power is 0.5W
AC 230V / 50Hz, + 5 Vsb load of 0.0A and input power of 0.5W
2.6 Remote ON/OFF control
When the logic level "PS-ON" is low, the DC outputs are to be enabled. When
the logic level is high or open collector, the DC outputs are to be disabled.
2.7 Dynamic loading
The PSU is subjected to a load change as shown in the table below at a rate
of 1A/μsec (unless otherwise specified).
The frequency of change is set to give the best readability of the deviation
and setting time.
All other output loads and the AC line voltage are chosen in order to obtain
the worst case condition

3. PROTECTION
3.1 Under voltage protection.
In an under voltage fault occurs, the supply will latch all DC outputs into a shut-
down state when +12V,+5V & +3.3V outputs under 60% of it's maximum value.
