Note - For P/G package devices only one of
either Line sensing or Overload power limiting
protection features can be used. For all
other packages both these functions can be
simultaneously used.
DC Bus Voltage at which the power supply will
start-up
DC Bus Voltage at which power supply will
shut-down
Use two standard, 2 MΩ, 5% resistors in series
for line sense functionality.
Zener Diode rated voltage for Output
Overvoltage shutdown protection
Output OVP resistor. For latching shutdown
use 20 ohm resistor instead
Enter the desired margin to current limit at
VMAX. A value of 1.2 indicates that the current
limit should be 20% higher than peak primary
current at VMAX
Margin to current limit at low line.
