Alpha’s LA Series voltage suppressors provide reliable protection of power supplies and
related equipment from the damaging power line disturbances common to cable TV and
broadband applications. The LA Series incorporates Metal Oxide Varistor (MOV) technology
that effectively limits voltage surges and absorb excessive energy levels. Housed in a durable
polymer casings with standard electrical plugs, the LA Series plugs directly into any electrical
outlet.

The ISA-120/240 Secondary Surge Arrester (Alpha P/N 062-041-10) is hard-wired and
protects electrical equipment and wiring against lightning induced surges. The arrester diverts
lightning surges to ground, and is designed to handle repetitive operations. Severe lightning
can cause the device to fail, and it should be replaced if either of the LEDs fails to light.
