Safety protections
  • Over Voltage protection - When the output voltage is over 150% rated voltage, the power supply will be protected, and will work normally when fault is removed or power on again.
  • Short Circuit protection -  The input power shall decrease when output rail short, the power supply shall no damage, and shall be self-recovery when the fault condition is removed.
  • DIELECTRIC STRENGTH Hi-Pot: Primary to secondary, 3000Vac(or 4242Vdc)  10mA  60S(2 second for production)
