All power supplies have to be equipped with various protections which do not only protect them from failures but also protect the system that is powered by them. Sometimes they are listed on specifications. What do they mean and how exactly does those help improve your LED drivers?
Here some explanation about protection.
OVP (Overvoltage protection)
If the voltages increase above a certain tolerance value on the single lines, the LED driver automatically switches off. Usually, it occurs in output terminal that does not connect well with LED. The failure of a pass transistor could easily put excess voltage on IC’s. With switchers, most failures cause no output at all.
SCP (Short-circuit protection)
In the case of a short-circuit, this feature prevents damage to the core components of the LED driver.
OPP (Overload protection)
If the system is oversized and requires more power from the LED driver than it can perform, this protection function is activated.
OCP (Overcurrent protection)
If the load on a single line is higher than indicated, the LED driver automatically switches off.
OTP (Over Temperature Protection)
When the over-temperature protection (OTP) is present, we usually find a thermistor attached to the secondary heat sink (the fan control unit usually uses a thermistor in the same heat sink). The thermistor informs the protections circuit about the temperature of the heat sink, and if this exceeds a specified threshold, then the output power shuts down. An excessive temperature may be a result of overloading or the cooling fan’s failure, so OTP prevents (further) damage to the LED driver.
How that help improve your LED drivers? They keep your light system safe, also the LED driver. The driver will not be damaged and protects itself. But the safety function is not a safety function. There are some extra components like a MOV to protect the system, and of course, the safety functions must be settled correctly. otherwise, the module is useless.
