2.4 Surge Protection Circuit

A metal oxide varistor (MOV) is often used to protect lighting systems from electrical surges

and ring-wave effects, and help manufacturers meet safety and performance standards. The MOV

prevents short-duration voltage impulse. Lightning tests (IEC 61000-4-5) and ring-wave

Tests (IEEE C.62.41) can be used for these real-life threat simulation in the lab.

A surge protection circuit (SPC) consists of two components (MOV & fusible resistor) and it is not

necessary for normal operation of the Acrich IC module.
