Protect your investment against power surges with this eight outlet, metal-encased surge suppressor, rated for surges up to 3600 joules. Its 25 foot grounded power cord allows you to reach distant outlets and the cord conveniently wraps around the body for storage. Includes 4 safety covers for unused outlets. Lighted power switch and surge protection indicator LED. Lifetime warranty from the manufacturer includes up to $100,000 US for replacement equipment should the surge suppressor fail, even in a direct lightning strike.

Since surge suppressor warranties do not cover damage when used with an extension cord, the long cord is a critical feature for portable planetarium systems. The suppressor will fit in the accessory area of portable Digitarium Alpha 2/2+, Zeta, Gamma, Epsilon, and Kappa systems (one is already included with new systems). UL Listed.

Two separate switches allow you to use 10 bright white LEDs for high illumination or three red LEDs to preserve your night vision. The anodized aluminum body is sturdy, corrosion resistant, and durable. Purchase includes a sewn nylon case with a pocket for spare batteries. Three AAA batteries required (included).
