The 0RQ1-T0S12B is an isolated DC/DC converter that operates from  
a nominal 48 VDC source. This unit provides up to 300 W of output  
power from a nominal 48 VDC input. This unit is designed to be highly  
efficient and low cost. Features include remote on/off, short circuit  
protection, over current protection, under voltage lockout and over-  
temperature protection. The converter is provided in an industry  
standard quarter brick package.

The OTP is achieved by temperature sensor and it is in non-latch mode when the hottest point on base plate reaches 105°C. It will restart  
automatically when the temperature falls down to 90°C. The protecting point will be varied a little under different conditions (air flow,  
ambient temperature, input voltage, load...)

To provide protection in a fault output overload condition, the module is equipped with internal current-limiting circuitry and can  
endure current limiting for a few milliseconds. If the over current condition persists beyond a few milliseconds, the module will shut  
down into hiccup mode and restart once every 400ms. The module operates normally when the output current goes into specified  
range. The typical average output current is 3A during hiccup.
