Minimum DC Bus Voltage at which the
power supply will start-up
Typical DC Bus Voltage at which power
supply will shut-down (Max)
Use two standard, 2 M-Ohm, 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
X pin functionality
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.
