Q1: How to select a suitable driver from the first point?
Firstly, forward current and power of a LED module is necessary. These could give an initial judge on the driver selection. The next step would be other required features depending on the application, like surge protection level, waterproof level etc.
Q2: What is SELV?
SELV stands for safety extra-low voltage.
Following is the definition from IEC60598-1:
A voltage which does not exceed 50 V a.c. r.m.s. between conductors, or between any conductor and earth, in a circuit which is isolated from the supply mains by means such as a safety isolating transformer or converter with separate windings.
