Short Circuit Protection (SCP)
DS1200-3 Series
Page 11
The DS1200 power supply will withstand a continuous short circuit with no permanent damage, applied to
its main output during start-up or while running.. A short is defined as impedance less than 0.1 ohms.
When the standby output V
is shorted the output will go into “hiccup mode”. When the V
attempts to restart, the
SB
SB
maximum peak current from the V
output will be less than 9.0A peak (3.3V) or 6.6A (5.0V). The maximum average
SB
current, taking into account the “hiccup” duty cycle, is less than 4.9A.
Over Temperature Protection (OTP)
The power supply is internally protected against over temperature conditions. When the OT circuit is activated, the power
supply will latch off, requiring AC power or PS_ON recycling to restart the power supply.
