The maximum rated values should NEVER be continuous from the load or else the module will be damaged.
Be sure to install correct circuit protection, such as fuses, to the input of the module to avoid overloading and the potential for fire.
If temperature exceeds 65°C please add cooling fan
Failure to take these precautions and incorrect use of this module may result in damage, fire, and/or personal injury.
Output setpoint voltage must always be lower than applied input voltage.
