2.5.1 POWER GOOD SIGNAL:
Signal Type: open collector +5DC, TTL compatible.
Logic Level: <0.4V while sinking 4 mA.
Logic Level High: between 2.4VDC and +5V output while sourcing 200 uA.
Max Ripple/Noise: 400mV pk-pk. (no capacitor test)
3.0 OUTPUT PROTECTION
3.1 TOTAL POWER PROTECTION: (OPP )
Total power 150% max with shut-down and latch off protection.
3.2 OVER VOLTAE PROTECTION: (OVP)
3.3 SHORT CIRCUIT PROTECTION: (SCP)
The short between any output of group 1 will shut down all group1.
The short at group 2 will Shut down both group 1 and group 2.
3.4 OVER CURRENT PROTECTION: (OCP)
Over current protection was designed to limit the current to operate within safe
operating conditions.Total current 160% max with shut-down and latch
off protection.
3.5 OVER TEMPERATURE PROTECTION: (OTP)
This power supply include an over-temperature protection sensor, which can trip
and shut down the power supply at a preset temperature point. Such an
overheated condition is typically the result of cooling fan failure or excessive
maximum operation temperature.
3.6 NO-LOAD SITUATION
No damage or hazardous condition should occur with all the DC output
connectors disconnected from the load. The power supply may latch into
the shutdown state.
